#66 1MORE Quad Driver: $119.69 Amazon eBay
Pros: The hybrid design combines one dynamic driver with three balanced armatures, and the 32 ohm impedance and 99 dB sensitivity let it run easily from a phone. It includes a built-in microphone for calls. The tuning leans warm, with bass about 4.3 dB above target, which suits listeners who like a thick low end.
Cons: Treble from 6 to 10 kHz sits about 6 dB under target and a 10.5 dB dip near 8.8 kHz dulls cymbals and detail, while the air region is boosted by 4.2 dB, which makes the top end uneven. Low mids run about 3.9 dB hot, adding bloat to male vocals and bass guitar, and sub-bass is down 4.5 dB so the deepest rumble is thin. The preference score of 45 and a rating below the BASN Bmaster show the tuning is a poor match for most tastes.
