#757 Sony MDR-7550 Discontinued eBay
Pros: Lower mids sit within about 0.5 dB of target, keeping voices and guitars natural. It uses 1 x 16mm dynamic with an easy 16 ohm load.
Cons: Discontinued, so it is mainly found used. Presence sits about 7.4 dB low with an 11.1 dB dip near 3.7 kHz, so vocals and instruments lose some bite. Sub-bass is 9 dB short at 30 Hz, so deep bass lacks rumble. A Harman score of 52 places it in the lower part of the in-ear rankings.
