Pros: Bass is lifted about 6.4 dB with extension to 20 Hz, giving kick drums and bass lines extra weight. Lower mids sit within about 1 dB of target, keeping voices and guitars natural. It uses 1 x 9mm dynamic.
Cons: A 7.5 dB peak near 6.2 kHz can make cymbals and sibilance sound sharp. The 6.4 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.
