#78 Kefine Klean: $53.61 Amazon eBay
Pros: Four squig.link measurements give the Klean a preference score of 79.4 with a very smooth 1.32 dB deviation from target. Sub-bass 1.3 dB and bass 2.1 dB above target give it a warm, rich low end that suits bassy tastes, while mids stay close to neutral. At 32 ohms and 107 dB it plays well from a phone, and it weighs 10 g.
Cons: A 5 dB dip near 9.9 kHz dulls the shimmer of cymbals and strings, and presence sits 1.9 dB below target, softening vocal edges. It costs more than the equally rated KZ Duonic and Sivga SM100.
