#176 Grado SR325x Discontinued eBay
Pros: Measured response gives it a very good Harman preference score of 75 with a 2.38 dB spread, and its mids sit within about 0.6 dB of target, so vocals and instruments sound natural. It uses 1 x 44mm dynamic.
Cons: Discontinued, so it is mainly found used. Presence sits about 4.2 dB low with a 7.6 dB dip near 3.7 kHz, so vocals and instruments lose some bite. A 4.5 dB peak near 2.1 kHz can make cymbals and sibilance sound sharp. Sub-bass is 10 dB short at 30 Hz, so deep bass lacks rumble.
