#119 Tanchjim 4U Discontinued eBay
Pros: The median of 17 hobbyist measurements gives it a very good Harman preference score of 79 with a 1.51 dB spread, and its mids sit within about 0.6 dB of target, so vocals and instruments sound natural. Upper treble lifts about 4.7 dB for extra air and sparkle. It uses 1 x dynamic (LCP composite diaphragm) with an easy 32 ohm load.
Cons: Discontinued, so it is mainly found used. Its 1.51 dB spread is less even than the best measured sets.
