#817 KZ ZS3 Discontinued eBay
Pros: Bass is lifted about 5.9 dB with extension to 20 Hz, giving kick drums and bass lines extra weight. Lower mids sit within about 0.8 dB of target, keeping voices and guitars natural. It uses 1 x dynamic with an easy 18 ohm load.
Cons: Discontinued, so it is mainly found used. A 7.6 dB peak near 5.8 kHz can make cymbals and sibilance sound sharp. The 5.9 dB bass lift can sound boomy and mask midrange detail. A Harman score of 46 places it in the lower part of the in-ear rankings.
