#41 EPZ G30: $79.99 Amazon eBay
Pros: Four hobbyist measurements on squig.link give it a preference score of 81.5 with a smooth 1.35 dB deviation. Bass sits about 0.9 dB above target with low mids close behind, giving a warm, full sound that suits bassy tastes. It weighs just 4.4 g per earbud and includes a built-in microphone, so it works for calls as well as music.
Cons: Presence falls about 3.2 dB below target, which tucks vocals slightly behind the instruments. A 5.0 dB peak near 8.1 kHz followed by a 5.6 dB dip near 11.9 kHz gives cymbals an uneven sheen and trims top-end air.
