#343 Kefine Delci: $58.50 Amazon $58.50 eBay
Pros: A warm, bass forward tuning measured by 31 people: sub-bass and bass sit about 2 to 3 dB above target with extension right down to 20 Hz, giving electronic and hip hop tracks satisfying weight. Mids stay clean with a 1.93 dB spread overall, and the light 5.3 g shell is comfortable for long sessions.
Cons: The 3 to 6 kHz presence region dips about 2.5 dB with a 3.3 dB low point near 3.5 kHz, so vocals sit slightly behind the bass. A 4.3 dB peak near 8.4 kHz can add some sharpness on cymbals, and listeners wanting a strictly neutral sound will find it bass heavy.
