#1 Truthear Nova: $169.99 Amazon eBay

Pros: A Harman score of 90 puts it among the best-tuned in-ears measured, with every band from sub-bass to presence within about 1.5 dB of the target. The deviation of only 0.86 dB means vocals, guitars and drums sound natural and evenly balanced. The hybrid design pairs a dynamic driver with four balanced armatures, and the 14.8 ohm impedance with 123 dB sensitivity lets a phone drive it easily. Sub-bass sits about 1.5 dB above target, adding a touch of rumble without muddying the mids.

Cons: A 2.7 dB peak near 8 kHz can make bright cymbals and sibilant vocals slightly edgy on poorly mastered tracks. Treble and air run about 1.3 to 1.4 dB hot, so listeners sensitive to brightness may find extended sessions a little sharp. It is wired only, with no microphone or wireless features listed.

#2 AKG N5005: $399.99 Amazon eBay

Pros: Bass, mids and presence all land within about 0.6 dB of the Harman target, giving a Harman score of 87 and a very smooth 1.11 dB deviation. Sub-bass is essentially on target at 0.1 dB below, so kick drums and bass lines have natural weight without bloat. The five-driver hybrid layout and 18 ohm impedance with 116 dB per volt sensitivity run fine from a phone. At 11.4 g per earbud it is light in the ear.

Cons: A 5.8 dB dip near 10 kHz and a 3.4 dB peak near 7.8 kHz leave the top end slightly uneven, taking some sparkle off cymbals and air. Treble from 6 to 10 kHz runs about 0.6 dB under target, so it can sound a touch laid back. It costs far more than the Truthear x Crinacle Zero RED, which has the same rating, so the premium buys refinement rather than a better rating.

#3 Truthear x Crinacle Zero RED: $64.99 Amazon eBay

Pros: A Harman score of 86 at an entry-level price delivers a well-balanced response with a smooth 1.1 dB deviation. Bass and mids track the target closely, and the dual dynamic driver design runs easily from a phone at 17.5 ohms and 117.5 dB per volt. It outscores the Tin HiFi T3 Plus by a clear rating margin at a similar cost. It is a good fit for listeners who like a warm, bass-forward sound.

Cons: Presence from 3 to 6 kHz sits about 2.2 dB below target, so vocals and snare attack can sound a little recessed. A 3.9 dB dip near 10.3 kHz and sub-bass about 1.4 dB light mean cymbals lack some shimmer and the deepest bass has less rumble. It is wired only with no mic or remote listed.

#4 7Hz Salnotes Zero: $22.99 Discontinued Amazon eBay

Newer model: the 7Hz x Crinacle Zero 2, ranked lower, rated 3.9/5, released Nov 2023. See every 7Hz Zero generation.

Pros: A Harman score of 84 from a single 10 mm dynamic driver at a bargain price is remarkable. Bass and mids sit within about 0.3 dB of the target, so vocals and instruments are balanced naturally with a 1.31 dB deviation. It runs from a phone without difficulty at 32 ohms and 108 dB per volt. It beats the 7Hz x Crinacle Zero 2 on rating at a similar cost.

Cons: Presence and treble run about 2.1 to 2.2 dB under target, and a 6.2 dB dip near 10 kHz leaves cymbals and breath detail muted. Sub-bass is about 1.5 dB light, so the deepest rumble in electronic music is understated. The sensitivity is lower than many rivals, so it needs a bit more volume headroom from weak sources. Discontinued.

#5 Truthear Gate: $21.99 Amazon eBay

Pros: A Harman score of 83 from a single dynamic driver at a very low price gives accurate bass and mids, with bass and upper mids within about 0.2 dB of target. The 28 ohm impedance with 122 dB per volt sensitivity makes it easy to drive from any phone. The warm tilt suits listeners who want a smooth, non-fatiguing sound. It earns the same rating as the 7Hz Salnotes Zero at a similar cost.

Cons: Treble is the weak point, with a deep 10.8 dB dip near 11 kHz and air about 3 dB under target. Cymbals, hi-hats and the sense of space on recordings sound dulled as a result. Presence from 3 to 6 kHz is also about 1.9 dB down, which takes a little bite off vocals.

#6 Final Audio A4000: $119.00 Amazon eBay

Pros: A Harman score of 80 shows it sits close to the target most listeners prefer, with a slightly bright tilt in crinacle’s measurement. It uses a compact 6 mm dynamic driver and weighs 18 g, so it is light in the ear. The 18 ohm impedance and 100 dB per mW sensitivity are manageable from a phone.

Cons: The 100 dB per mW sensitivity is lower than many in-ears, so it needs more volume from weak sources. No built-in microphone is offered, which limits it for calls. It is wired only, so it lacks the wireless convenience of the Sony WF-1000XM5, which has a lower rating.

#7 Shuoer S12: $129.00 Amazon eBay

Pros: A planar magnetic driver is unusual in an in-ear and gives a Harman score of 80 with a smooth 1.62 dB deviation. Bass is lifted about 1.9 dB, adding warmth and punch, while the upper mids and treble stay close to target. The 16 ohm impedance is easy to drive from a phone, and it matches the Final Audio A4000 on rating.

Cons: A 4.2 dB peak near 8.2 kHz can make cymbals and sibilants slightly sharp, and treble from 6 to 10 kHz runs about 1.6 dB hot. Presence from 3 to 6 kHz sits 2.4 dB under target with a 3.3 dB dip near 3.75 kHz, so vocals can lose some forwardness. The 102 dB per mW sensitivity asks for a bit more volume than efficient rivals.

#8 Moondrop Blessing 3: $359.99 Amazon eBay

Pros: A Harman score of 79 in crinacle’s measurement shows a tuning that lands close to what most listeners prefer, with a slightly bright tilt. Six drivers, two dynamic and four balanced armature, handle bass and treble separately. The 14.8 ohm impedance and 120 dB per volt sensitivity let a phone drive it comfortably. It rates the same as the Etymotic EVO and higher than the AUNE Jasper.

Cons: It costs noticeably more than the Etymotic EVO, which has an equal rating, so the extra money does not buy a better score. The AKG N5005 rates higher still, with a better Harman score. Wired only, with no microphone listed.

#9 Sennheiser IE 200: $129.95 Amazon eBay

Pros: Bass and midrange land almost exactly on the Harman target in oratory1990’s measurement, within about 0.5 dB from 60 Hz to 3 kHz, which gives a natural tonal balance and a preference score of 79. At 16 ohms and 119 dB SPL/V sensitivity it plays loud straight from a phone with no amp. Each earpiece weighs only 4 g, and the single 7mm dynamic driver is a simple, wired design with no battery to charge.

Cons: The presence region from 3 to 6 kHz sits about 5 dB under target, with a 5.7 dB dip near 4.4 kHz, so vocals and snare attacks sound a little recessed. The top octave runs about 5.8 dB hot, which adds sparkle that can read as thin or bright on some recordings. The Final Audio A4000 and Shuoer S12 carry higher ratings at lower prices.

#10 Etymotic EVO: $298.98 Amazon eBay

Pros: Three balanced armature drivers deliver a flat, uncolored midrange, with the 1 to 3 kHz region within 0.5 dB of the Harman target and a preference score of 78. Response is smooth, with a standard deviation of 1.89 dB around target. The deep-insertion wired design is passive noise isolating, and the 47 ohm impedance still works from a phone or dongle.

Cons: Bass is lean, with sub-bass about 3.3 dB under target and the 60 to 200 Hz region 1.5 dB under, so kick drums and bass lines have less weight than most listeners prefer. Treble from 6 to 10 kHz is about 3.5 dB low and the response drops 7.4 dB near 11.9 kHz, which makes cymbals and air sound dull. Sensitivity of 99 dB at 0.1V is modest, so volume needs more headroom than the most efficient earphones.

#11 Sony WF-1000XM5: $198.00 Amazon eBay

Pros: Mild bass emphasis, about 1.9 dB above target from 60 to 200 Hz, adds warmth without muddying the midrange, which stays within 0.8 dB of the target for a preference score of 78. Active noise cancelling, LDAC, AAC and SBC support, Bluetooth 5.3 and an IPX4 rating make it a full-featured true wireless set. Battery lasts about 8 hours per charge, 24 with the case, and each bud weighs 5.9 g.

Cons: Treble from 6 to 10 kHz runs about 2.2 dB low, with a 4.9 dB dip near 8 kHz, so cymbals and sibilance lose some bite. A 2.9 dB peak near 10.6 kHz can add a touch of artificial shimmer. Sub-bass sits about 1.9 dB below target, so the bass is punchy more than deep. The wired Sennheiser IE 200 matches its rating at a lower price and without charging.

#12 Tin HiFi T3 Plus: $59.00 Amazon eBay

Pros: Crinacle’s measurement gives a preference score of 77 with a smooth response, a standard deviation of only 1.78 dB around the target. A single 10mm dynamic driver at 32 ohms and 105 dB sensitivity runs easily from a phone or dongle. It scores well above the Tin HiFi T4, which has a lower rating at a higher price.

Cons: The tilt of negative 0.41 means a slightly warm balance, so listeners who want a brighter, airier sound may find it relaxed. It has no built-in microphone, so it cannot take calls. It is wired only, with no wireless or noise cancelling features.

#13 Kiwi Ears Orchestra Lite: $249.00 Amazon eBay

Pros: Bass and lower midrange land within about 0.2 dB of the Harman target from 60 Hz to 1 kHz, so vocals and instruments sound natural and unboosted. The response is smooth, with a deviation of only about 2 dB around the target and a preference score of 76. Eight balanced armature drivers and 112 dB sensitivity make it easy to drive from a phone or portable player, and it suits warm and bass leaning tastes.

Cons: Presence from 3 to 6 kHz runs about 5.6 dB under target, with a 6.7 dB dip near 3.6 kHz, so voices and guitars sound recessed and a little veiled. Treble from 6 to 10 kHz is about 2.8 dB low, which softens cymbals and reduces sparkle. It is rated below the Etymotic EVO, and there is no built in microphone.

#14 Moondrop Quarks: $17.99 Amazon eBay

Pros: A preference score of 76 from a very inexpensive wired in-ear is hard to beat, and it is rated above the KZ ZSN Pro X and the CCA CRA. Bass from 60 to 200 Hz is lifted about 2.2 dB over target and the low mids about 1.6 dB, giving a warm, full sound that fits warm and bass leaning tastes. At 16 ohms and 116 dB sensitivity it plays loud straight from a phone.

Cons: A 4 dB peak near 2.9 kHz can make female vocals and snare hits sound forward or slightly shouty at higher volumes. Air above 10 kHz is about 2.5 dB low and there is a 5.4 dB dip near 11.9 kHz, so the top end sounds less open and airy. Sub-bass under 60 Hz is about 1.8 dB below target, so the deepest notes lack a little rumble.

#15 SoftEars RSV: $729.00 Amazon eBay

Pros: A preference score of 76 in crinacle’s measurement shows a response that sits close to the Harman target, and it is rated above the FiiO FD5 and the HIFIMAN RE2000. Five balanced armature drivers with 8 ohms impedance and 125 dB sensitivity mean it runs easily from a phone or dongle. The wired design suits home or portable listening with a source of your choice.

Cons: It sits at a premium price for an in-ear, and a preference score of 76 is no higher than far cheaper wired sets achieve. The very low 8 ohm impedance can interact with sources that have a high output impedance, and 125 dB sensitivity can make hiss from noisy sources audible. It is wired only, with no built in microphone.

#16 AUNE Jasper: $239.00 Amazon eBay

Pros: A single 10mm dynamic driver reaches a preference score of 75 in crinacle’s measurement, with a nearly neutral tilt of 0.01. At 32 ohms and 102 dB/mW it is easy to drive from a phone or small dongle. The manufacturer quotes a frequency range of 5 Hz to 40 kHz, and the wired design needs no charging.

Cons: Response is less even than the best in its class, with a standard deviation of 2.29 dB around the target, so some peaks and dips color vocals and treble. The Etymotic EVO has a higher rating and a smoother measurement, though at a higher price. It has no wireless features, noise cancelling or listed microphone.

#17 Beats Powerbeats Pro: $189.99 Discontinued Amazon eBay

Pros: Bass and midrange follow the Harman target closely, with 60 to 200 Hz within 0.2 dB and upper mids 0.7 dB above, so voices and bass lines sound natural and warm for a preference score of 75. The true wireless design adds Bluetooth 5.0 with SBC and AAC, a built-in microphone and an IPX4 rating. Battery lasts about 9 hours per charge, 24 with the case.

Cons: Treble is well under target, about 5.2 dB low from 6 to 10 kHz, with an 8.5 dB dip near 6.8 kHz, so cymbals, hi-hats and sibilance sound muted. The air band above 10 kHz is another 4.4 dB low, which adds to a dark, closed-in sound. It has no active noise cancelling, and the Etymotic EVO has a higher rating. Discontinued.

#18 FiiO FH5s: $254.99 Amazon eBay

Pros: A preference score of 75 in crinacle’s measurement points to a response close to the Harman target, and it is rated above the Samsung Galaxy Buds2 and the Shuoer S12 Pro. The hybrid design pairs a 12 mm and a 6 mm dynamic driver with two balanced armature drivers. At 40 ohms and 106 dB sensitivity it is easy to drive from a phone, and each earbud weighs 8.8 g.

Cons: Its score and rating are about the same as the AUNE Jasper and the Beats Powerbeats Pro, so it does not stand out in its class. The tilt leans slightly bright, which may not suit listeners who prefer a warm sound. It is wired only, with no built in microphone.

#19 KZ ZSN Pro X: $23.99 Amazon eBay

Pros: The hybrid design with a 10mm dynamic driver and a balanced armature gives bass about 3.6 dB above target at 60 to 200 Hz, which adds punch and warmth for pop and hip hop. A preference score of 74 at an inexpensive price is strong, and the 25 ohm impedance with 112 dB/mW sensitivity makes it easy to drive from a phone. It also suits a warm or v-shaped taste.

Cons: A 7.2 dB peak near 8.1 kHz and an air band about 5.8 dB above target can make cymbals and s sounds sharp or hissy at higher volume. The 3 to 4 kHz region dips about 2.9 dB, so vocals can sound a little distant. It has no wireless features or noise cancelling.

#20 Samsung Galaxy Buds2: $199.00 Discontinued Amazon eBay

Pros: Bass and low mids sit slightly above target, about 0.9 dB at 60 to 200 Hz, which gives a warm, easy tonal balance for a preference score of 74. The set offers active noise cancelling, Bluetooth 5.2, a microphone, and SBC, AAC and Scalable codec support. Each bud weighs 5 g, and a dual driver layout pairs an 11mm woofer with a 6.3mm tweeter.

Cons: Treble is uneven, with a 5.8 dB peak near 8 kHz, a 4.8 dB dip across 3 to 6 kHz, and the air band 6.5 dB low, which blurs vocal detail and makes cymbals sound splashy and then rolled off. Battery lasts about 5 hours with noise cancelling on. The IPX2 rating gives only basic splash protection, and the AUNE Jasper has a higher rating. Discontinued.

Pros: A 14.8mm planar magnetic driver delivers a gentle bass lift, about 2 dB above target from 60 to 200 Hz, with sub-bass nearly on target, for a preference score of 74. At 16 ohms and 102 dB sensitivity it runs fine from a phone. The wired design suits warm and v-shaped tastes, with extra treble sparkle.

Cons: Treble from 6 to 16 kHz runs 3 dB or more above target, with a 6 dB peak near 8.2 kHz, so cymbals and sibilance can sound bright at volume. A 5.5 dB dip near 3.7 kHz pulls back vocal presence. The Beats Powerbeats Pro and AUNE Jasper carry higher ratings.

#22 7Hz x Crinacle Zero 2: $24.99 Amazon eBay

Older model: the 7Hz Salnotes Zero (ranked higher, rated 4.8/5). See every 7Hz Zero generation.

Pros: Crinacle’s measurement gives a preference score of 73 with a response that stays fairly even, a standard deviation of 1.99 dB around target. A 10mm dynamic driver at 32 ohms and 108 dB SPL/V sensitivity runs from a phone with no amp. The low cost makes it an easy entry into wired in-ears.

Cons: The tilt of negative 0.71 is the warmest in this group, so treble detail and air can sound subdued. It has no wireless features, noise cancelling or listed microphone. The KZ ZSN Pro X has a higher rating at a similar price.

#23 KZ ZSN Pro: $24.99 Amazon eBay

Pros: A preference score of 73 in HypetheSonics’ measurement is solid for a wired set this cheap, with a response that stays within about 2.2 dB of the Harman target. Bass sits roughly 3 dB above target from 60 to 200 Hz, adding punch to kick drums and bass guitar without muddying the lower midrange, which stays within 1 dB. At 25 ohms and 104 dB/mW it runs loudly from a phone, and the hybrid dynamic plus balanced armature design suits v-shaped and warm tastes. It also rates higher than the MEE Audio M6 Pro.

Cons: Treble above 10 kHz runs about 6 dB hot, with a sharp 9.4 dB peak near 11 kHz that can make cymbals and hi-hats sound glassy or hissy. A 3.7 dB dip near 3.4 kHz pulls vocals and snare snap slightly back. Listeners who want a flat, neutral tuning will find the bass and treble both exaggerated.

A single 10mm dynamic driver at 32 ohms and 102 dB is easy to power from a phone or dongle, and it rates a little higher than the KZ ZAX at a similar level of price.

Cons: The score still leaves room for audible deviations from the target, so some tonal coloration is likely. A single dynamic driver also gives up the added detail that multi-driver sets in this class aim for.

#25 CCA CRA: $20.99 Amazon eBay

Pros: A preference score of 72 in crinacle’s measurement is strong for one of the least expensive wired sets in its class, and the 1.98 dB deviation from target is among the smoothest in this group. The 111 dB sensitivity and 23.5 ohm impedance mean a phone drives it to high volume with ease. The slightly warm tilt suits listeners who like a touch of extra bass.

Cons: The tuning is a notch below the best sets in the class, and the slightly warm lean can soften treble detail for those who prefer a brighter sound. It has no listed frequency range or other extras, so the case for it rests on the tuning and low cost.

#26 CCA C12: $48.99 Amazon eBay

Pros: A preference score of 71 in crinacle’s measurement is respectable for a hybrid with one dynamic driver and five balanced armatures. The 24 ohm impedance and 112 dB/mW sensitivity make it easy to drive from any phone. A slightly warm tilt gives it a fuller, more relaxed presentation than a bright set.

Cons: The 2.2 dB deviation from the target shows the response still wanders, so tonal balance will not be fully natural. Crowding six drivers into one housing does not translate into a score above cheaper single-driver sets like the CCA CRA, which has a higher rating.

#27 KZ ZAX: $65.99 Amazon eBay

Pros: A preference score of 71 in crinacle’s measurement comes from a hybrid design with one dynamic driver and seven balanced armatures. At 24 ohms and 113 dB the sensitivity is very high, so any phone or dongle drives it easily. The slightly warm tilt keeps treble from turning harsh.

Cons: The response sits 2.3 dB from the target on average, so some coloration remains despite the eight drivers. It also costs noticeably more than the CCA C12 for the same rating, and the Tin HiFi T4 rates higher with a single dynamic driver.

#28 MEE Audio M6 Pro: $39.99 Amazon eBay

Pros: A preference score of 71 in crinacle’s measurement is a decent result for a single 10mm dynamic driver. At 16 ohms and 100 dB/mW it is simple to drive from a phone, and the slightly warm tilt gives a smooth, easy listen. Its rating matches the CCA C12 and KZ ZAX.

Cons: The 100 dB/mW sensitivity is the lowest in this group, so it needs a little more volume than the hybrids. The 2.2 dB deviation from the target leaves audible coloration, and the 7Hz x Crinacle Zero 2 rates higher at a lower price.

#29 TANGZU Wan’er S.G: $18.00 Amazon eBay

Pros: A preference score of 71 in crinacle’s measurement at a very low cost is good value, with a mildly warm tilt that keeps treble from becoming harsh. Each earbud weighs only 4.2 g, and a built-in microphone makes it usable for calls. It rates higher than the KZ ZST and costs less.

Cons: The 2.5 dB deviation from the target is the least smooth of this group, so tonal accuracy trails the CCA CRA and KZ ZSN Pro, both of which rate higher. A single 10mm dynamic driver and no listed impedance or sensitivity leave less to go on for matching it with a source.

#30 SoftEars Twilight: $930.00 Amazon eBay

Pros: A preference score of 71 with a deviation of 2.42 dB from target is a respectable result for a single-dynamic-driver in-ear. A 16 ohm impedance and 116 dB/V sensitivity let it run loudly and cleanly from a phone or portable player without extra amplification. It weighs only 6 g per earbud, and its tilt of -0.1 means it is close to tonally balanced rather than skewed warm or bright. It has a higher rating than the HIFIMAN RE2000 and the JVC HA-FW1500.

Cons: The score of 71 is well short of the best in-ears, so some tuning errors remain against the Harman target. The SoftEars RSV from the same brand has a higher rating. It is a wired design only.

#31 CCA C10: $40.99 Amazon eBay

Pros: A preference score of 70 in crinacle’s measurement comes from a hybrid with one dynamic driver and four balanced armatures. At 32 ohms and 108 dB/mW it works comfortably from phones, and the slightly warm tilt makes for a relaxed sound.

Cons: The 2.3 dB deviation from the target leaves noticeable coloration, and the preference score trails the CCA C12 and MEE Audio M6 Pro, both of which rate higher. The extra balanced armatures do not lift it above simpler single-driver sets.

#32 FiiO FD5: $505.28 Amazon eBay

Pros: A preference score of 70 in crinacle’s measurement comes from a single large 12mm dynamic driver. At 32 ohms and 109 dB/mW it needs no dedicated amp, and the slightly warm tilt gives a full, smooth presentation. It also rates higher than the Audio-Technica ATH-CK2000Ti.

Cons: The 2.4 dB deviation from the target is no better than far cheaper sets in this class, which makes the high price hard to justify on tuning alone. The Moondrop Blessing 3 rates much higher for substantially less, and at 11 g per earbud it is on the heavier side for an in-ear.

#33 KZ ZST: $21.99 Amazon eBay

Pros: In oratory1990’s measurement the preference score is 70, with bass about 2.3 dB above target from 60 to 200 Hz for extra warmth and punch, and sub-bass tracking the target within 0.1 dB. The low mids and upper mids stay within about 1 dB, so vocals and instruments sit naturally. The warm and bassy profiles fit it best, and the hybrid pairing of one dynamic and one balanced armature driver costs very little.

Cons: A 9.4 dB dip near 4.4 kHz and 3.7 dB lower presence from 3 to 6 kHz pull back vocal clarity and the attack of snares and guitars. Above 10 kHz the response runs about 6.5 dB hot, with a 10 dB peak near 11 kHz that adds sharpness to cymbals. The TANGZU Wan’er S.G rates higher.

#34 HIFIMAN RE2000: $799.00 Amazon eBay

Pros: Crinacle’s measurement gives a Harman preference score of 69 with a deviation of 2.63 dB, a respectable match to the target most listeners prefer. The tonal balance is close to neutral, with a tilt of only 0.32 dB toward brightness, so it avoids sounding either dark or harsh.

Cons: A score of 69 is only middling for a flagship in-ear, and a response that deviates from the target by 2.63 dB leaves audible coloration. The wired-only design has no built-in mic or wireless option. The FiiO FD5 carries a higher rating at a notably lower cost, which makes this model a hard sell on sound value.

#35 TFZ T2 Galaxy: $59.00 Amazon eBay

Pros: Oratory1990’s measurement shows sub-bass about 3.7 dB and bass about 3.5 dB above the Harman target, which gives kick drums and bass lines a solid, punchy foundation that suits bassy and V-shaped tastes. The 16 ohm impedance and 110 dB/mW sensitivity mean it plays loud from a phone without an amp. The preference score of 69 is respectable for a budget wired in-ear, and its 12 mm dynamic driver stays simple and easy to drive.

Cons: A peak of 4.9 dB near 8 kHz can make cymbals and sibilant vocals sound sharp. Output above 10 kHz sits roughly 4.3 dB under target, with a 6.2 dB dip near 11.9 kHz, so the top end loses air and sparkle. The bass boost of more than 3 dB can also make male vocals and low instruments sound heavier than they should. There is no built-in microphone.

#36 TRN MT1: $13.95 Amazon eBay

Pros: Crinacle’s measurement gives a Harman preference score of 69, a solid result for such an inexpensive wired in-ear. A 22 ohm impedance and 106 dB sensitivity let it run loudly from any phone or laptop without an amp. It includes an inline microphone for calls, and the single 10 mm dynamic driver keeps the sound coherent.

Cons: A deviation of 2.46 dB from the target means some coloration remains in the midrange and treble. The wired connection means no wireless freedom, and the CCA CRA is rated higher at a similar cost.

Pros: The 14.2 mm planar magnetic driver is an uncommon design at this size, and Crinacle’s measurement gives a Harman preference score of 69 with an almost flat tilt of 0.05 dB, so the balance is neither warm nor bright. Its 16 ohm impedance and claimed 10 Hz to 20 kHz response suit a wide range of sources.

Cons: The 98 dB sensitivity is on the low side for an in-ear, so it benefits from a stronger source than a basic phone dongle. A deviation of 2.79 dB around the target is the roughest of its group, which means audible peaks and dips remain. The Samsung Galaxy Buds2 and Shuoer S12 Pro are both rated higher at a lower cost. There is no listed microphone or wireless connection.

#38 KZ ZS10 Pro: $44.99 Amazon eBay

Pros: Five drivers per side, one dynamic and four balanced armature, give a hybrid layout rare at this price, and Crinacle’s measurement returns a Harman preference score of 69. The 24 ohm impedance and 111 dB sensitivity make it easy to drive from a phone. The slight warm tilt of 0.43 dB below neutral keeps the balance relaxed.

Cons: A deviation of 2.44 dB from the target leaves some uneven spots across the frequency range. The hybrid design is wired only and lists no microphone. The CCA C12 is rated higher at a similar cost.

#39 iBasso IT04: $499.00 Amazon eBay

Pros: A preference score of 69 in crinacle’s measurement puts the IT04 in solid, listenable territory for an in-ear. The 110 dB sensitivity means it is easy to drive from a phone or dongle without a dedicated amp. At 13 g with a hybrid of one 10mm dynamic driver and three balanced armatures, it is light and uses a driver mix aimed at bass weight plus detail.

Cons: A score of 69 trails the best in-ears, so the tuning is noticeably off the Harman target in places. The FiiO FD5 has a higher rating at a similar price, which makes it the safer pick if the Harman fit matters most. It is wired only, with no wireless option.

#40 KZ PR1: $87.99 Amazon eBay

Pros: The 13.2 mm planar magnetic driver is an unusual choice at this size, and Crinacle’s measurement gives a Harman preference score of 67 with a deviation of 2.36 dB. The 16 ohm impedance suits portable sources, and the 20 Hz to 40 kHz claimed range is wide.

Cons: Sensitivity of 96 dB is low for an in-ear, so volume headroom from a phone can be limited and a stronger source helps. A tilt of 0.76 dB toward the warm side gives a darker balance than the target. The TFZ T2 Galaxy is rated higher and costs less. No microphone is listed.

#41 Sennheiser IE 40 Pro: $109.00 Amazon eBay

Pros: Oratory1990’s measurement shows bass 1.0 dB and low mids 1.4 dB above target, a gentle warmth that suits relaxed listening, and the preference score of 67 is acceptable. A 20 ohm impedance and 115 dB SPL/V sensitivity mean a phone drives it with ease, which suits monitoring and portable use. The balance leans toward warm and V-shaped tastes.

Cons: Presence is 4.5 dB under target across 3 to 6 kHz, with a 6.4 dB dip near 3.1 kHz, so vocals and guitars sound recessed and detail is dulled. Sub-bass is 3.6 dB light, so deep rumble is absent. Then the top end swings the opposite way, with a peak of 8.3 dB at 11.9 kHz and air 5.7 dB over target, which can add a brittle sheen. Tonal balance is clearly uneven, with a deviation of 2.94 dB.

#42 CCA CSN: $25.99 Amazon eBay

Pros: A hybrid pairing of a 10 mm dynamic driver and a balanced armature gives Crinacle’s measurement a Harman preference score of 67, which is solid for a very inexpensive wired set. With 22.5 ohms and 112 dB/mW sensitivity it plays loud from a phone. The slight warm tilt of 0.46 dB keeps it from sounding harsh.

Cons: A deviation of 2.64 dB from the target leaves clear coloration in places. It is wired only with no microphone listed. The MEE Audio M6 Pro, CCA C10 and KZ ZST are all rated higher at close to the same cost.

#43 JVC HA-FW1500: $766.28 Amazon eBay

Pros: The 11 mm dynamic driver rates a manufacturer specified 6 Hz to 52 kHz, and Crinacle’s measurement shows a Harman preference score of 66 with a mild warm tilt of 0.53 dB. The 16 ohm impedance and 103 dB/mW sensitivity make it easy for a phone to drive. It has been out since late 2019.

Cons: A score of 66 is middling and a deviation of 2.69 dB means audible coloration, which is hard to justify at a flagship price. The HIFIMAN RE2000 and FiiO FD5 are both rated higher, and the FiiO costs far less. It is wired only and lists no microphone.

#44 Sennheiser Momentum True Wireless 3: $111.99 Discontinued Amazon eBay

Newer model: the Sennheiser MOMENTUM True Wireless 4, ranked lower, rated 3.3/5, released Feb 2024. It adds LC3. See every Sennheiser Momentum True Wireless generation.

Pros: Active noise cancelling, Bluetooth 5.2 and aptX Adaptive support (alongside SBC, AAC and aptX) add real convenience, and battery life is 7 hours per charge with up to 28 hours using the case. At 5.8 g per earbud with an IPX4 rating, it handles workouts and light rain. Oratory1990’s measurement shows bass and sub-bass within 1 dB of target, giving a clean, warm foundation that suits warm and bassy tastes.

Cons: Presence between 3 and 6 kHz is 6.9 dB under target with a 7.6 dB dip near 4.4 kHz, so vocals, snare and guitar edges sound distant and veiled. Air above 10 kHz runs 5.4 dB hot, with a peak of 4.9 dB near 10.5 kHz, which adds a hissy edge on top of the recessed mids. The preference score of 66 and deviation of 2.59 dB confirm the response sits well off the target. The KZ PR1 is rated higher at a similar cost, though it lacks wireless and ANC. Discontinued.

#45 Whizzer HE01: $45.00 Amazon eBay

Pros: Crinacle’s measurement gives a Harman preference score of 66, which puts the tuning in decent territory for a budget in-ear. The 18 ohm impedance and 112 dB/mW sensitivity make it easy to drive from a phone or dongle without an amp. A single dynamic driver and a slightly warm tilt suit relaxed, bass-forward listening.

Cons: The response is uneven, with a standard deviation of 2.78 dB around the target, so some instruments will sound tonally off. There is no built-in microphone, so it only works for music and not for calls.

Pros: A Harman score of 66 in Crinacle’s measurement shows the tuning lands reasonably close to what most listeners prefer. The 16 ohm impedance and 109 dB/mW sensitivity mean a phone can drive it to loud levels. At 8 g per earbud with a 10mm dynamic driver, it is a light, simple wired set.

Cons: Deviation from the target averages 2.84 dB, so the response is not especially smooth. Without an inline microphone it cannot be used for calls, and the KZ PR1 has a higher rating.

#47 FiiO FH3: $119.99 Amazon eBay

Pros: Bass and sub-bass sit within about 1 dB above the Harman target, giving kick drums and bass guitar a full, warm foundation without bloat. The hybrid design pairs a 10mm dynamic driver with two balanced armatures, and 114 dB/mW sensitivity at 24 ohms means a phone runs it easily. A preference score of 65 suits listeners who like a warm, bassy tilt.

Cons: The 3 to 6 kHz presence region sits about 5.7 dB below target, with a dip of 7.4 dB near 6.5 kHz, so vocals and cymbals lose bite and detail. Treble from 6 to 10 kHz is also about 2.2 dB low, which makes the sound dark and a little veiled. The KZ PR1 has a higher rating.

#48 Sennheiser MOMENTUM True Wireless 4: $249.95 Amazon eBay

Older model: the Sennheiser Momentum True Wireless 3 (ranked higher, rated 3.4/5). See every Sennheiser Momentum True Wireless generation.

Pros: This true wireless set adds active noise cancelling, Bluetooth 5.4 and a codec list that runs from SBC and AAC up to aptX Lossless and LC3. Battery life is 7.5 hours per charge and 30 hours with the case, and IP54 resistance covers sweat and light rain. Oratory1990’s measurement shows bass about 0.6 dB above target, so low end is full without being overdone.

Cons: Presence from 3 to 6 kHz is about 6.9 dB under target, with an 8.2 dB dip near 5.7 kHz, so voices and guitars sound recessed. Air above 10 kHz runs 5 dB hot with a peak of 4.2 dB near 10.6 kHz, which can add a thin, sparkly edge. The Tin HiFi P1 Max has a higher rating, for a lower price.

#49 FiiO FH7S: $299.99 Amazon eBay

Pros: Oratory1990 measured bass about 4.6 dB above the Harman target, so kick drums and bass lines hit with real weight for a hybrid built around a 13.6mm dynamic driver and four balanced armatures. Treble is close to target, and an 18 ohm impedance makes it easy to drive from a phone despite the 104 dB/mW sensitivity. It suits warm, bassy tastes.

Cons: Low mids run 2.4 dB hot on top of the bass lift, which can make male vocals and bass instruments thick. A 6.1 dB peak near 8 kHz can make cymbals and sibilants sharp. The Tin HiFi P1 Max and FiiO FD5 both have higher ratings.

#50 SoundMAGIC E50C: $32.99 Amazon eBay

Pros: Bass from 60 to 200 Hz sits within 0.3 dB of target, so the low end is balanced rather than boomy. The inline microphone makes it usable for calls, and the 51 ohm impedance with 102 dB/mW sensitivity works with most phones. It is a very low-cost way into a warm tuning, with a preference score of 64.

Cons: Presence from 3 to 6 kHz is about 6.7 dB under target, with an 8.7 dB dip near 3.3 kHz, so vocals lose clarity and sound set back. Sub-bass is 2.8 dB low and the top octave is about 3.8 dB down, which limits both rumble and air. The Whizzer HE01 has a higher rating.

#51 KZ ATE: $17.99 Amazon eBay

Pros: Bass from 60 to 200 Hz runs about 6.8 dB above target, with sub-bass up 2.8 dB, which delivers punchy, energetic low end for the money. The 16 ohm impedance and 106 dB sensitivity make it easy to power from a phone, and the V-shaped balance with a lift up to 4.3 dB in the 6 to 10 kHz range gives a lively, sparkling sound.

Cons: A 9 dB peak near 8.3 kHz makes cymbals and sibilants splashy and fatiguing at higher volumes. The bass lift of nearly 7 dB can overwhelm the low mids, adding 3.1 dB of thickness to male vocals. The CCA CSN has a higher rating at a similar budget.

#52 Sennheiser IE 900: $1,299.95 Amazon eBay

Pros: Oratory1990 measured sub-bass and bass within about 1.2 dB of target, so the low end is tidy and controlled. Sensitivity of 123 dB SPL/V and a 16 ohm impedance make it easy to drive from a phone, and the 7mm dynamic driver is rated to reach from 5 Hz to 48 kHz. Top-octave air sits about 3.6 dB above target for an open, detailed treble.

Cons: Presence from 3 to 6 kHz is about 6.7 dB below the Harman target, with an 8.8 dB dip near 3.6 kHz, which recesses vocals and removes some bite. A preference score of 63 is modest for such a premium product, and the HIFIMAN RE2000 has a higher rating at a lower price.

#53 Shure SE215: $109.00 Amazon eBay

Pros: Bass from 60 to 200 Hz is lifted by about 4.2 dB with low mids up 2.2 dB, giving a warm, full sound that suits rock, pop and hip hop. A 17 ohm impedance and 107 dB SPL/mW sensitivity make it easy to drive from a phone, and the single dynamic driver keeps the design simple. Upper mids sit right on target, so vocals are not pushed back.

Cons: Treble from 6 to 10 kHz is about 3 dB low with a 5.9 dB dip near 6.7 kHz, and the top octave is down 2.7 dB, so cymbals and air sound dull. The warm balance can make the mix feel thick. The iBasso IT01S and the FiiO FH3 both have higher ratings.

#54 Etymotic ER4XR: $299.00 Amazon eBay

Pros: Upper mids sit within 0.5 dB of the Harman target and low mids within 0.4 dB, so vocals and instruments come through clearly and naturally. Oratory1990’s measurement gives a preference score of 62, and the single balanced armature driver suits listeners who want a neutral, analytical presentation without added bass.

Cons: Sub-bass is about 7.2 dB under target and bass is 2.6 dB low, so kick drums and bass lines lack weight and rumble. Treble from 6 to 10 kHz is 5.4 dB low, with an 8.6 dB dip near 6.7 kHz, which dulls cymbals. A 45 ohm impedance makes it a bit harder to drive than most phone-friendly earphones, and the FiiO FH7S has a higher rating.

#55 FiiO FH5: $1,127.26 Amazon eBay

Pros: In oratory1990’s measurement the bass and low mids sit only 0.6 to 1.4 dB above the Harman target, so kick drums and bass guitar have a warm, full body without bloating. The hybrid design pairs a 10mm dynamic driver with 3 balanced armatures, and the 19 ohm impedance and 112 dB/mW sensitivity mean a phone or dongle drives it easily. Sub-bass is slightly lifted by 0.8 dB, which suits warm and bassy tastes.

Cons: Presence between 3 and 6 kHz runs about 7.3 dB under target, with a 9.6 dB dip near 4.7 kHz, so vocals, snare and guitar attack sound recessed and distant. Air above 10 kHz is down about 3.2 dB, which takes some sparkle off cymbals. A preference score of 61 and an uneven response with a 2.96 dB deviation leave it behind the HIFIMAN RE2000 for tonal accuracy.

#56 Audio-Technica ATH-CK2000Ti: $750.00 Amazon eBay

Pros: The dual phase push-pull design uses two dynamic drivers (9.8mm and 8.8mm) per side, and the manufacturer quotes a very wide 5 Hz to 45 kHz range. At 10 ohms and 100 dB/mW it works from a phone or portable player without a dedicated amp. Crinacle’s measurement gives a preference score of 60, with a mild warm tilt of about 0.8 dB.

Cons: A preference score of 60 and a 2.97 dB deviation from the target mean the tonal balance is noticeably off for most listeners. It is rated below the FiiO FH5 and well below the HIFIMAN RE2000, which offer more accurate tuning at similar money. No inline microphone or other convenience features are listed.

#57 HIFIMAN RE400: $19.99 Amazon eBay

Pros: A very low price makes it an easy backup pair or first wired earphone. The single 8.5mm dynamic driver, 32 ohm impedance and 102 dB/mW sensitivity work fine straight from a phone or laptop. Crinacle’s measurement shows a slightly bright tilt of about 0.6 dB, which gives a lean, light presentation for those who dislike bass-heavy sound.

Cons: A preference score of 60 with a 3.29 dB deviation from the target means the response is quite uneven, so some instruments and vocals will sound colored. There is no built-in microphone, so it cannot take calls. The KZ ATE and SoundMAGIC E50C are rated higher at a similar price.

#58 KZ AS10: $59.99 Amazon eBay

Pros: Five balanced armature drivers per side at a modest price is an unusual configuration for a wired earphone. The 14 ohm impedance and 105 dB/mW sensitivity make it easy to drive from a phone or dongle. Crinacle’s preference score of 60 with a 2.91 dB deviation puts its tonal balance ahead of the Sennheiser CX 3.00 and 1MORE Triple Driver in rating.

Cons: A preference score of 60 means the tuning is still well off the target most listeners prefer, with a slightly warm tilt of about 0.9 dB. No microphone is listed, so it is for music only. The iBasso IT01S is rated clearly higher for a modest step up in cost.

#60 Jabra Elite Active 65t: $156.45 Discontinued Amazon eBay

Pros: A true wireless design with an IP56 rating gives dust and sweat resistance suited to workouts. Battery life is 5 hours per charge and 15 hours with the case, and the earbuds weigh only 6.5 g each. Bluetooth 5.0 and a built-in microphone cover calls and everyday listening.

Cons: Only the SBC codec is supported, so there is no higher quality Bluetooth option. There is no active noise cancelling, and Crinacle’s measurement gives a preference score of 58 with a 3.41 dB deviation from target, so the tuning is uneven. The Shure SE215 and FiiO FH3 are rated higher and cheaper, though both are wired. Discontinued.

Crinacle measured a warm tilt of about 1.1 dB, a good match for those who prefer a gentle, bass-leaning sound.

Cons: A preference score of 58 and a 2.91 dB deviation from the target indicate an uneven balance that colors vocals and instruments. No microphone is listed, so calls are not an option. The KZ DQ6S, KZ ATE and CCA CSN are all rated higher at a similar cost.

#62 Sennheiser CX 3.00: $79.99 Amazon eBay

Pros: Bass is boosted about 4 dB at 60 to 200 Hz and 2.5 dB below that in oratory1990’s measurement, so kick drums and bass lines hit with extra weight. Treble from 6 to 10 kHz is lifted about 6 dB, which adds a bright edge to cymbals and gives it a V-shaped character some listeners enjoy. The 18 ohm impedance and 118 dB SPL/V sensitivity let a phone drive it easily.

Cons: A sharp 8.6 dB peak near 7.6 kHz can make hi-hats and sibilants harsh, and presence between 3 and 6 kHz is down about 4.3 dB, with a 5.7 dB dip near 3.5 kHz that pushes vocals back. A preference score of 58 and a 3.19 dB deviation mean the balance is far from the target. The Shure SE215 and FiiO FH3 are rated higher.

#63 1MORE Triple Driver: $69.99 Amazon eBay

Pros: A hybrid design with 1 dynamic and 2 balanced armature drivers, plus a built-in microphone for calls. It was released in 2017 and the 32 ohm impedance suits a phone or portable player. Crinacle measured a mild warm tilt of about 0.8 dB.

Cons: A preference score of 57 and a 3.28 dB deviation from the target put the tonal balance among the weaker in its class. Sensitivity of 99 dB is on the low side, so it needs more volume than most earphones. The KZ AS10 and Sennheiser CX 3.00 are rated higher, and the Shure SE215 is higher still.

#64 Final Audio E3000: $46.60 Amazon eBay

Pros: Bass at 60 to 200 Hz sits about 5.5 dB above the Harman target in oratory1990’s measurement, and the low mids are lifted about 3.2 dB, giving a warm, full and weighty sound. Treble from 6 to 10 kHz is only 1.6 dB over target, so highs stay fairly gentle and non-fatiguing. The single 6.4mm dynamic driver is easy to drive at 16 ohms and 100 dB/mW, and the price is low.

Cons: The strong bass and low mid lift can muddy vocals, and presence from 3 to 6 kHz is down about 3 dB with a 3.7 dB dip near 4.5 kHz, so voices lack clarity. A preference score of 57 with a 3.4 dB deviation shows the balance is far from target. The KZ AS10, KZ DQ6S and SoundMAGIC E50C are all rated higher.

#65 BASN Bmaster: $91.99 Amazon eBay

Pros: The hybrid driver setup pairs two dynamic drivers with a balanced armature, and the wired connection means no battery or pairing to manage. In HypetheSonics’ measurement bass sits about 2.6 dB above the Harman target and sub-bass is close to target, so the tuning suits listeners who want a warm, bass-forward sound. It also rates higher than the 1MORE Quad Driver at a lower price.

Cons: Presence from 3 to 6 kHz runs about 8.8 dB under target, with a 9.5 dB dip near 4 kHz, so vocals and guitars lose bite and sound recessed. Treble and air are also down by roughly 3.7 dB and 8.1 dB, which leaves cymbals dull and the overall sound closed in. The preference score of 49 is well below what most listeners prefer.

#66 1MORE Quad Driver: $119.69 Amazon eBay

Pros: The hybrid design combines one dynamic driver with three balanced armatures, and the 32 ohm impedance and 99 dB sensitivity let it run easily from a phone. It includes a built-in microphone for calls. The tuning leans warm, with bass about 4.3 dB above target, which suits listeners who like a thick low end.

Cons: Treble from 6 to 10 kHz sits about 6 dB under target and a 10.5 dB dip near 8.8 kHz dulls cymbals and detail, while the air region is boosted by 4.2 dB, which makes the top end uneven. Low mids run about 3.9 dB hot, adding bloat to male vocals and bass guitar, and sub-bass is down 4.5 dB so the deepest rumble is thin. The preference score of 45 and a rating below the BASN Bmaster show the tuning is a poor match for most tastes.

#67 Sennheiser Momentum True Wireless 2: $237.45 Amazon eBay

Pros: Active noise cancelling, Bluetooth 5.1 with SBC, AAC and aptX, and an IPX4 rating cover the features commuters and gym users want. Battery life is rated at 7 hours per charge and 28 with the case, and each earbud weighs only 6 g. Bass is lifted by about 3.1 dB over target, which suits listeners who want a warm, punchy sound.

Cons: In oratory1990’s measurement the presence region from 3 to 6 kHz is about 9.6 dB below target, with a 10.7 dB dip near 4 kHz, so vocals and instrument attack sound pushed back and hazy. A 5.2 dB peak near 10.8 kHz and boosted air then add an uneven sparkle on top, and sub-bass is down 2.3 dB. The preference score of 44 is low, and the rating sits below the Jabra Elite Active 65t.

#68 Panasonic RP-HJE120: $10.99 Amazon eBay

Pros: It is a very cheap wired earphone with a 9 mm dynamic driver, 16 ohm impedance and 95 dB/mW sensitivity, so it plays loud from any phone or laptop. Bass is lifted about 8 dB over target in oratory1990’s measurement and sub-bass is up 2.3 dB, which suits listeners who simply want a big, thumpy low end.

Cons: That bass boost spills into the low mids, which are 4.8 dB over target, so vocals and instruments sound thick and muddy. Treble is rolled off by about 2.2 dB and air by 4.3 dB, with an 8.7 dB dip near 11.9 kHz, so cymbals lack sparkle. The preference score of 40 is the lowest among its rivals, and each of those rivals has a higher rating, including the TRN MT1 at a similar cost.
