#802 KZ ZSR Discontinued eBay
Pros: Bass is lifted about 3.7 dB with extension to 20 Hz, giving kick drums and bass lines extra weight. Lower mids sit within about 0.7 dB of target, keeping voices and guitars natural. It uses 1 x 10mm dynamic + 2 x balanced armature with an easy 22 ohm load.
Cons: Discontinued, so it is mainly found used. Presence sits about 7.4 dB low with a 17.4 dB dip near 4.6 kHz, so vocals and instruments lose some bite. An 11.3 dB peak near 8.2 kHz can make cymbals and sibilance sound sharp. A Harman score of 48 places it in the lower part of the in-ear rankings.
