#355 Superlux HD 651 eBay
Pros: Lower mids sit within about 0.5 dB of target, keeping voices and guitars natural. It uses 1 x 40mm dynamic with an easy 32 ohm load.
Cons: Presence sits about 3.4 dB low with a 17.4 dB dip near 9.7 kHz, so vocals and instruments lose some bite. Sub-bass is 20.1 dB short at 30 Hz, so deep bass lacks rumble. A Harman score of 51 places it in the lower part of the over-ear rankings.
