Etymotic ER3SE vs 1MORE Quad Driver

Last updated: October 11, 2026

Short answer: the Etymotic ER3SE, though neither ranks well in its class. It ranks #430 of 450 in-ear headphones by sound quality, rated 2.0/5, at $149.99. The 1MORE Quad Driver ranks #438, rated 1.7/5, at $119.69, $30.30 cheaper, which does not close the gap in sound quality. Both are rated below 3.0/5 among the 450 in-ear headphones, so if sound quality matters, consider the Truthear Nova instead, ranked #2 at $169.99.

Etymotic ER3SE vs 1MORE Quad Driver

The Etymotic ER3SE is the better-sounding option. A single balanced armature at 22 ohms and 102 dB/mW reaches comfortable volume from any phone or laptop without an amp. The catch: In oratory1990’s measurement sub-bass sits 9.9 dB below target and falls 6 dB short as high as 67 Hz, so bass lines sound thin and lack weight.

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.

Buy the Etymotic ER3SE. It is rated higher for sound quality, and the $30.30 saving on the 1MORE Quad Driver is not enough to make up the difference.

Etymotic ER3SE ranking card

Pros: A single balanced armature at 22 ohms and 102 dB/mW reaches comfortable volume from any phone or laptop without an amp. Its tuning lines up best with listeners who lean toward a neutral or warm taste rather than a bass-heavy one. It carries a higher rating than the pricier Westone W10.

Cons: In oratory1990’s measurement sub-bass sits 9.9 dB below target and falls 6 dB short as high as 67 Hz, so bass lines sound thin and lack weight. The treble drops 9.5 dB under target from 6 to 10 kHz with a 13.8 dB dip near 11.8 kHz, leaving cymbals and detail dull, and a preference score of 49 with 4.18 dB of deviation means most listeners hear it as colored. There is no built-in microphone for calls.

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.
