#891 Audio-Technica ATH-CK3TW TWS Discontinued eBay
Pros: Bass is lifted about 6.1 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 5.8mm dynamic with an easy 16 ohm load.
Cons: Discontinued, so it is mainly found used. Presence sits about 7.5 dB low with a 9.7 dB dip near 4.0 kHz, so vocals and instruments lose some bite. A 6.4 dB peak near 8.9 kHz can make cymbals and sibilance sound sharp. The 6.1 dB bass lift can sound boomy and mask midrange detail. A Harman score of 28 places it in the lower part of the in-ear rankings.
