Final Audio Heaven IV Discontinued eBay
Pros: Lower mids sit within about 0.5 dB of target, keeping voices and guitars natural. It uses 1 x balanced armature with an easy 16 ohm load.
Cons: Discontinued, so it is mainly found used. Presence sits about 6.7 dB low with a 12.9 dB dip near 11.2 kHz, so vocals and instruments lose some bite. Sub-bass is 5.5 dB short at 30 Hz, so deep bass lacks rumble. A Harman score of 56 places it in the lower part of the in-ear rankings.
