#4 Moondrop Quarks DSP Discontinued eBay
Pros: Measured response gives it an excellent Harman preference score of 88 with a 0.99 dB spread, and its mids sit within about 0.7 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 6mm dynamic with an easy 16 ohm load.
Cons: Discontinued, so it is mainly found used. Its 0.99 dB spread is less even than the best measured sets.
