#691 1MORE Single Driver Discontinued eBay
Pros: Lower mids sit within about 0.6 dB of target, keeping voices and guitars natural. It uses 1 x 8mm dynamic with an easy 32 ohm load.
Cons: Discontinued, so it is mainly found used. A 4.7 dB peak near 5.2 kHz can make cymbals and sibilance sound sharp. Sub-bass is 6.9 dB short at 30 Hz, so deep bass lacks rumble. A Harman score of 59 places it in the lower part of the in-ear rankings.
