#459 Letshuoer S12 Ultra: $169.00 Amazon $169.00 eBay
Pros: The median of 12 hobbyist measurements gives it a solid Harman preference score of 69 with a 2.18 dB spread, and its mids sit within about 0.5 dB of target, so vocals and instruments sound natural. It uses 1 x 14.8mm planar magnetic with an easy 16 ohm load.
Cons: Presence sits about 4 dB low with a 6 dB dip near 3.4 kHz, so vocals and instruments lose some bite. A 4.2 dB peak near 8.2 kHz can make cymbals and sibilance sound sharp.
