Fostex TH500RP - ranked #381 of 417 Over-Ear Headphones · Editor's rating 2.4/5

#381 Fostex TH500RP Discontinued eBay

Pros: Lower mids sit within about 0.5 dB of target, keeping voices and guitars natural.

Cons: Discontinued, so it is mainly found used. Presence sits about 7.5 dB low with a 10.3 dB dip near 3.8 kHz, so vocals and instruments lose some bite. Sub-bass is 22.7 dB short at 30 Hz, so deep bass lacks rumble. A Harman score of 45 places it in the lower part of the over-ear rankings.
