Sony MDR-XB50 - ranked #843 of 865 In-Ear Headphones · Editor's rating 1.4/5

#843 Sony MDR-XB50 Discontinued eBay

Pros: Bass is lifted about 6.9 dB with extension to 20 Hz, giving kick drums and bass lines extra weight. Lower mids sit within about 1.1 dB of target, keeping voices and guitars natural. It uses 1 x 12mm dynamic.

Cons: Discontinued, so it is mainly found used. Presence sits about 3.7 dB low with a 6.2 dB dip near 3.0 kHz, so vocals and instruments lose some bite. A 5.9 dB peak near 9.4 kHz can make cymbals and sibilance sound sharp. The 6.9 dB bass lift can sound boomy and mask midrange detail. A Harman score of 42 places it in the lower part of the in-ear rankings.
