#688 Anker Soundcore Liberty Air 2 TWS Discontinued eBay
Pros: Bass is lifted about 4.6 dB with extension to 20 Hz, giving kick drums and bass lines extra weight. Upper treble lifts about 5.3 dB for extra air and sparkle. Lower mids sit within about 0.5 dB of target, keeping voices and guitars natural.
Cons: Discontinued, so it is mainly found used. A 5.1 dB peak near 11.3 kHz can make cymbals and sibilance sound sharp. The 4.6 dB bass lift can sound boomy and mask midrange detail. A Harman score of 59 places it in the lower part of the in-ear rankings.
