#217 Dan Clark Audio Aeon X Open Discontinued eBay
Pros: Lower mids sit within about 0.8 dB of target, keeping voices and guitars natural.
Cons: Discontinued, so it is mainly found used. Sub-bass is 4.2 dB short at 30 Hz, so deep bass lacks rumble. A Harman score of 62 places it in the lower part of the over-ear rankings.
