The Best Neutral Headphones 2026

A neutral headphone adds nothing: no bass boost, an even midrange and treble that’s neither lifted nor rolled off. It suits mixing, critical listening and anyone who wants to hear recordings the way they were balanced, without the low-end lift most consumer tunings add.

The ranking measures how closely each model matches the Harman target with its bass shelf removed, leaving a flat low end. Listeners used to consumer headphones may find these lean at first. Each class shows its 15 closest matches, out of the models with a full published measurement.

Over-Ear Headphones

Ranked #76 of 134 in Over-Ear Headphones - Shure SRH1840: $549.00 Amazon eBay

Pros: The response leans neutral to slightly bright, with upper mids about 1.8 dB above target and presence and treble within about 1 dB, which makes vocals and instrument detail clear. The preference score of 71 and 2.29 dB deviation reflect a smooth, even midrange and treble. It is an open back at 268 g.

Cons: Sub-bass is about 7.5 dB under target and bass is about 1.8 dB low, so kick drums and bass guitar are thin and lack rumble. A 4.4 dB peak near 3.1 kHz can make voices and strings sound forward or slightly harsh at higher volumes. At 65 ohms and 96 dB/mW sensitivity it benefits from a proper headphone amplifier, and the open back leaks sound. The Denon AH-D5200 earns a higher rating among its rivals.

Ranked #21 of 134 in Over-Ear Headphones - Audio-Technica ATH-M70x: $329.00 Amazon eBay

Pros: A preference score of 87 and a fairly smooth 1.6 dB deviation make it one of the closer closed-back models to the Harman target. Bass from 60 to 200 Hz lands within 1 dB of target, and sub-bass is only about 2 dB light, so low end is tidy without being thin. At 35 ohms and 97 dB sensitivity it is easy to drive from a laptop or interface, and the closed design isolates and does not leak into a room.

Cons: Presence is lifted by about 3 dB with a peak of 4.6 dB near 4.5 kHz, which adds bite to vocals, snares and guitars and can become fatiguing at higher volumes. Treble above 6 kHz also runs slightly hot, so bright recordings sound sharper than neutral. At 280 g it is heavier than many open-back rivals in its class.

Ranked #36 of 134 in Over-Ear Headphones - Audio-Technica ATH-R50x: $169.00 Amazon eBay

Pros: A preference score of 83 and the smoothest deviation in this group at 1.67 dB make for a very even response, with bass from 60 to 200 Hz and low mids within 0.6 dB of target. At 50 ohms and 93.3 dB/mW sensitivity it can be driven by most portable sources, and at 207 g it is light. It costs less than the AKG K701 and AKG K702 while holding the same rating.

Cons: Sub-bass is about 6 dB low under 60 Hz, so deep rumble is lacking. Treble is slightly forward, with presence about 2 dB high, 6 to 10 kHz about 2.6 dB high and a 4.8 dB peak near 6.3 kHz, which can make vocals and cymbals bright. Its tilt of 0.64 leans bright, and the open back leaks sound.

Ranked #53 of 134 in Over-Ear Headphones - Philips SHP9500: $94.99 Amazon eBay

Pros: A preference score of 80 and a deviation of only 2.2 dB make the open back response smooth for the money, with bass from 60 to 200 Hz and the lower mids within half a dB of target. It is very easy to drive at 32 ohms and 101 dB sensitivity, so a phone runs it fine, and it weighs just 320 g. It costs far less than most headphones with a comparable score.

Cons: Sub-bass is about 9 dB below target under 60 Hz, so electronic and cinematic bass lacks rumble and slam. Presence is lifted about 2.3 dB, and a 6.7 dB peak near 6.2 kHz followed by a 4 dB dip near 7.7 kHz adds some edge to vocals and cymbals. The open back leaks sound and gives no isolation.

Ranked #20 of 134 in Over-Ear Headphones - Sennheiser HD 505: $199.95 Amazon eBay

Pros: A preference score of 88 in oratory1990’s measurement puts it among the closest to the Harman target, with the midrange from 200 Hz to 6 kHz within about 0.5 dB of target, so vocals and instruments sound natural and unforced. The 120 ohm impedance and 107.9 dB per volt sensitivity let it run from a decent DAC or portable amp, and at 237 g the open-back design is light.

Cons: Sub-bass under 60 Hz sits about 6 dB below target, so deep synth bass and kick drum weight are thin. A narrow 9 dB dip near 9.9 kHz and treble running about 2.7 dB low soften cymbals and make it a little dark on airy recordings. Being open-back it leaks sound and offers no isolation.

Ranked #40 of 134 in Over-Ear Headphones - Sony MDR-7506: $129.99 Amazon eBay

Pros: A preference score of 83 with a deviation of only 1.7 dB from the Harman target in oratory1990’s measurement is excellent for a closed studio headphone. Bass and low mids sit within about 1 dB of target, so vocals and instruments sound natural and uncolored. At 260 g with a 106 dB/mW sensitivity, it plays loud straight from a phone or laptop without an amp.

Cons: Presence and treble run about 3.5 dB hot, with a peak of 6 dB near 4.5 kHz, which makes vocals forward and cymbals or sibilance sharp at higher volumes. Air above 10 kHz is about 2.6 dB low, and the wired-only design has no microphone.

Ranked #5 of 134 in Over-Ear Headphones - Sennheiser HD 560S: $199.95 Amazon eBay

Pros: It scores 93 on the Harman preference model, with the midrange and presence region (200 Hz to 6 kHz) within about 0.2 dB of target, so vocals and instruments sound very natural. At 240 g it is the lightest of the top group, and the open design gives a wide soundstage. Its 120 ohm impedance is still manageable from most modern sources.

Cons: Bass is lean, with sub-bass about 5 dB under target and 60 to 200 Hz about 1.2 dB under, which can sound thin on pop, hip hop and electronic music. Treble is also pulled back, with a deep 8.5 dB dip near 9.8 kHz that softens cymbals and sibilance. The open back leaks sound and provides no isolation.

Ranked #3 of 134 in Over-Ear Headphones - HIFIMAN Ananda Nano: $319.00 Amazon eBay

Pros: A preference score of 94 puts it close to the Harman target, with bass from 60 to 200 Hz within 0.1 dB of target and the midrange within about 1 dB. Impedance of just 14 ohms makes it simple to drive from a phone or dongle, and the open planar design gives a spacious presentation. Sub-bass is only moderately light, about 2.8 dB under target.

Cons: The top end is the weak spot, with the air region above 10 kHz running about 4.6 dB hot and a 10.8 dB peak near 11.9 kHz, preceded by a 4.4 dB dip near 9.6 kHz. That can make cymbals and strings sound bright or sharp on some recordings. At 420 g it is heavy, and the open back leaks sound and gives no isolation.

Ranked #22 of 134 in Over-Ear Headphones - HIFIMAN Shangri-La Jr: $8,000.00 Amazon eBay

Pros: An electrostatic driver with a preference score of 87 and an unusually even response, with every band from 60 Hz to 10 kHz within about 1.4 dB of the Harman target. The air region above 10 kHz runs about 1 dB above target, giving a sense of space and fine detail. Its rating sits just above the HIFIMAN Susvara and well above the Focal Utopia 2022.

Cons: Sub-bass below 60 Hz is about 5 dB under target, so deep rumble is understated. A 7 dB dip near 9.7 kHz is followed by a 5 dB peak near 11.9 kHz, which reshapes the top end into something slightly uneven. As an electrostatic design it needs a dedicated energizer, and at 374 g it is not a casual portable option.

Ranked #45 of 134 in Over-Ear Headphones - Sony MDR-ZX310: $77.09 Amazon eBay

Pros: A preference score of 82 is strong for a budget headphone, and the response stays within 2.4 dB of the Harman target in oratory1990’s measurement. Midrange tracks target closely, within about 1 dB, for natural vocals. At 125 g with 24 ohm impedance and 98 dB/mW sensitivity, it is light and runs loud from any phone, and the closed back blocks some noise.

Cons: Sub-bass below 60 Hz is about 17.5 dB under target, so deep bass is effectively missing, and bass from 60 to 200 Hz is also 2.2 dB low. A dip of nearly 11 dB near 11 kHz and weak treble make music sound dull and closed in. Choose the Sony MDR-7506 for a similar rating with a brighter, more detailed sound.

Ranked #7 of 134 in Over-Ear Headphones - Sennheiser HD 600: $272.36 Amazon eBay

Pros: It earns a preference score of 91, with the midrange from 200 Hz to 6 kHz within about 0.1 dB of target, giving vocals and acoustic instruments a very natural tone. At 260 g it is light, and the long-running design from 1997 remains a reference for neutral midrange tuning. The warm and neutral tilt suits listeners who dislike bright treble.

Cons: Sub-bass is about 7.9 dB below target, so bass lacks rumble and weight on electronic and hip hop tracks. Treble from 6 to 10 kHz is about 3.6 dB low, with a 7.5 dB dip near 9.6 kHz that softens cymbals. At 300 ohms and 97 dB SPL/V it needs a dedicated headphone amp for proper volume, and the open back leaks sound.

Ranked #33 of 134 in Over-Ear Headphones - HIFIMAN HE6se V2: $792.24 Amazon eBay

Pros: A preference score of 84 with a deviation of only 2.19 dB shows a smooth, well-controlled response, and low mids sit within 2 dB of target. Bass from 60 to 200 Hz is within 1 dB of target, so bass notes keep their body. It costs noticeably less than the HIFIMAN HE1000 Stealth, though that model carries a higher rating.

Cons: Sub-bass is roughly 4 dB under target below 60 Hz, so the lowest rumble is missing. Presence is about 2.5 dB hot with a 3.7 dB peak near 3.75 kHz, and a 5 dB dip near 9.6 kHz softens cymbals. At 83.5 dB sensitivity it needs a dedicated headphone amp, and the open back leaks sound.

Ranked #116 of 134 in Over-Ear Headphones - Koss KSC75: $19.99 Amazon eBay

Pros: An extremely low cost and a featherweight 43 g clip-on design make it easy to carry and wear for long stretches. The midrange is close to target, with the low mids within 0.2 dB, so voices sound natural, and the slightly lifted treble of about 2 to 3 dB adds clarity. The open back gives an airy sound, and 101 dB sensitivity at 60 ohms works from a phone.

Cons: Sub-bass is about 17 dB below target under 60 Hz, so there is almost no rumble and bass-heavy music sounds thin. Bass in the 60 to 200 Hz range is also about 2 dB low, and a 4 dB peak near 5.3 kHz can add some edge. The open design leaks sound and gives no noise isolation.

Ranked #13 of 134 in Over-Ear Headphones - Audeze LCD-XC: $1,199.00 Amazon eBay

Pros: A preference score of 89 and a 1.9 dB deviation show an overall balance that follows the Harman target closely with a neutral tilt. Upper mids are within half a dB of target, so voices sit naturally in the mix. The closed-back planar design isolates better than most high-end headphones and runs from a phone or laptop at 20 ohms and 100 dB/mW sensitivity.

Cons: Bass is clearly recessed, about 6 dB light in the sub-bass and about 2 dB light from 60 to 200 Hz, so kick drums and bass guitar lack weight. An 8.5 dB dip near 9.3 kHz and a 3 dB shortfall through the treble also soften cymbals and sibilance. At 677 g it is a heavy headphone, and it is rated below the HIFIMAN Arya Organic and Dan Clark Audio Noire X.

Ranked #15 of 134 in Over-Ear Headphones - HIFIMAN HE400se: $109.00 Amazon eBay

Pros: A preference score of 89 and a neutral tilt make this an accurate sounding planar for the money. Treble is within a fraction of a dB of target and the air band is only 1 dB high, so the top end is smooth and free of sharp peaks, with the largest at about 2.4 dB near 11.9 kHz. It matches the rating of the Beyerdynamic DT 880 at a lower price, with a modest 396 g weight.

Cons: Sub-bass is about 5 dB light and bass from 60 to 200 Hz is about 1 dB under target, so low end impact is limited. The low mids are about 1.6 dB elevated while a 4.8 dB dip near 2 kHz and a 2 dB upper mid shortfall can push vocals slightly back. At 91 dB/mW sensitivity it benefits from a headphone amp, and the open back leaks sound and provides no isolation.

Ranked #54 of 68 in In-Ear Headphones - 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.

Ranked #10 of 68 in In-Ear Headphones - 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.

Ranked #3 of 68 in In-Ear Headphones - 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.

Ranked #4 of 68 in In-Ear Headphones - 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.

Ranked #2 of 68 in In-Ear Headphones - 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.

Ranked #14 of 68 in In-Ear Headphones - 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.

Ranked #9 of 68 in In-Ear Headphones - 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.

Ranked #5 of 68 in In-Ear Headphones - 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.

Ranked #11 of 68 in In-Ear Headphones - 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.

Ranked #13 of 68 in In-Ear Headphones - 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.

Ranked #41 of 68 in In-Ear Headphones - 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.

Ranked #1 of 68 in In-Ear Headphones - 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.

Ranked #7 of 68 in In-Ear Headphones - 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.

Ranked #20 of 68 in In-Ear Headphones - 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.

Ranked #19 of 68 in In-Ear Headphones - 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.
