#19 Cozoy D1: $35.89 AliExpress $35.89 eBay
Pros: The median of 26 hobbyist measurements gives it an excellent Harman preference score of 84 with a 1.14 dB spread, and its mids sit within about 1.1 dB of target, so vocals and instruments sound natural. Bass sits close to target and holds down to 20 Hz, so low end sounds full without bloat. It uses 1 x 10mm dynamic with an easy 32 ohm load.
Cons: A 4.3 dB peak near 11.2 kHz can make cymbals and sibilance sound sharp.
