1MORE Quad Driver vs Shozy B2

Short answer: the 1MORE Quad Driver, though neither ranks well in its class. Both are rated 1.7/5 for sound quality (#438 and #437 of 450 in-ear headphones), and the 1MORE Quad Driver costs $119.69 against $169.99 for the Shozy B2, so with nothing between them on sound quality, price settles it. Both are rated below 3.0/5 among the 450 in-ear headphones, and the Truthear Nova, ranked #2 at $169.99, is a better place to start if sound quality matters.

What the 1MORE Quad Driver does well: 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. The tradeoff: 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.

What the Shozy B2 does well: The closed in-ear design blocks outside noise and keeps music private. The catch: Crinacle’s measurement gives it a preference score of only 46 with 4.0 dB of deviation from the Harman target, so most listeners will hear it as noticeably colored.

Buy the 1MORE Quad Driver. Both are rated the same for sound quality, and it costs $50.30 less than the Shozy B2.

The Two Headphones In Full

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.

Shozy B2: $169.99 Amazon eBay

Pros: The closed in-ear design blocks outside noise and keeps music private. Its warm tilt suits listeners who like a darker, less bright sound. It holds a slightly higher rating than the pricier Oriolus Finschi Hifi.

Cons: Crinacle’s measurement gives it a preference score of only 46 with 4.0 dB of deviation from the Harman target, so most listeners will hear it as noticeably colored. The Westone W10 earns a higher rating.
