Ranked #23 of 297 in In-Ear Headphones - TRN MT3: $17.99 Amazon eBay
Pros: The MT3 scores 83.4 for preference in the median of eight hobbyist measurements on squig.link, with a smooth 1.18 dB deviation from target. Sub-bass sits right on target and bass runs about 1.6 dB above it, giving kick drums and electronic music a slightly warm, full low end that suits warm and mildly V shaped tastes. Its 114 dB sensitivity at 28 ohms means any phone or dongle drives it loudly.
Cons: Treble is lifted, about 2 dB high from 6 to 10 kHz and 3.6 dB high above 10 kHz, with a 5.1 dB peak near 8.4 kHz that can make sibilance and cymbals sound splashy. A 3.7 dB dip near 11.2 kHz follows, so the top end is not entirely even. It is rated equal to, not above, close rivals such as the 7Hz Salnotes Zero and CCA Trio.

Ranked #89 of 297 in In-Ear Headphones - TRN Conch: $29.99 Amazon eBay
Pros: Fifteen hobbyist measurements on squig.link give the Conch a preference score of 79.0, a strong result for one of the cheapest in-ears around. Bass runs 2.1 dB above target with sub-bass holding on target to 20 Hz, giving music warm weight for V-shaped tastes. Its 114 dB sensitivity and 30 ohm impedance make it simple to drive from a phone.
Cons: Air above 10 kHz sits about 5.8 dB above target with a 6.7 dB peak near 8.1 kHz, so it can sound sharp and sibilant on bright recordings. The presence band 2 dB below target recesses vocals a little, and the KBEAR KB01 earns a higher rating at a similar price.

Ranked #93 of 297 in In-Ear Headphones - TRN Medusa: $53.99 Amazon eBay
Pros: Thirteen hobbyist measurements on squig.link put the Medusa at a preference score of 78.7, with a single 12mm dynamic driver that holds bass almost exactly on target down to 30 Hz. Midbass sits 1.7 dB above target for punchy drums, while vocals in the 1 to 3 kHz range come through clearly. It weighs 5.1 g per earbud and its 30 ohm, 108 dB load is easy for any phone.
Cons: The air band runs about 6.5 dB above target and peaks 8.6 dB near 11.9 kHz, so it can sound hissy and fatiguing with bright mixes or at high volume. It costs a little more than the equally rated KBEAR KB02 and CCA Pianist.

Ranked #188 of 297 in In-Ear Headphones - TRN MT1: $13.95 Amazon AliExpress eBay
Pros: A preference score of 69 in crinacle’s measurement is a strong result for one of the cheapest in-ears around. Sub-bass is on target down to 30 Hz with bass 2.5 dB above, so it has satisfying punch, and the single 10 mm dynamic driver runs loud from any phone at 22 ohms and 106 dB. An inline microphone handles calls.
Cons: A 10.4 dB peak near 11.9 kHz in hobbyist measurements on squig.link can make cymbals sound tizzy and fatiguing at volume, with a 6 dB dip at 6.5 kHz just below it. The CCA CRA and TANGZU Wan’er S.G are rated higher for only a few dollars more.
