JVC HA-FW01 - ranked #634 of 668 In-Ear Headphones · Editor's rating 1.9/5

#634 JVC HA-FW01 Discontinued eBay

Pros: Bass is lifted about 4.5 dB with extension to 20 Hz, giving kick drums and bass lines extra weight. Lower mids sit within about 0.6 dB of target, keeping voices and guitars natural. It uses 1 x 11mm wood dome dynamic with an easy 16 ohm load.

Cons: Discontinued, so it is mainly found used. The 4.5 dB bass lift can sound boomy and mask midrange detail. Treble sits about 5.3 dB low, so it sounds a little dark. A Harman score of 48 places it in the lower part of the in-ear rankings.
