#99 KZ ASX: $131.99 Amazon eBay
Pros: Ten balanced armature drivers per side run easily from a phone thanks to 20 ohm impedance and 106 dB/mW sensitivity. Bass sits about 4.1 dB above target in the squig.link median, so listeners who want a bassy, warm signature get extra punch.
Cons: A deep 13.2 dB dip near 7.3 kHz and treble about 5.9 dB below target leave cymbals and detail dull, while a 5.1 dB peak near 1.7 kHz can make vocals sound pushy and nasal. The Zero Audio Duoza ZH-DWX10 rates slightly higher for less money.
