#92 Kefine Quatio: $129.00 Amazon eBay
Pros: In the median of 13 squig.link measurements it scores 78.8 with a smooth 1.38 dB spread and no treble peak above 1.5 dB, so cymbals and sibilance never turn harsh. Bass rises about 1.8 dB above target with full extension to 20 Hz, giving a warm, full low end that suits bass lovers. Its 32 ohm, 107 dB load is easy to drive from a phone.
Cons: A 4 dB dip near 3.6 kHz and presence about 2.5 dB under target push vocals slightly back and soften attack. The air band runs 1.3 dB low, so it sounds less airy and spacious than brighter rivals, and the equally rated 7Hz Salnotes Dioko costs less.
