#863 Final Audio F4100 Discontinued eBay

Pros: Lower mids sit within about 0.5 dB of target, keeping voices and guitars natural. It uses 1 x balanced armature.

Cons: Discontinued, so it is mainly found used. Presence sits about 8.6 dB low with a 14.3 dB dip near 5.8 kHz, so vocals and instruments lose some bite. Sub-bass is 14.6 dB short at 30 Hz, so deep bass lacks rumble. A Harman score of 38 places it in the lower part of the in-ear rankings.
