Short answer: the Zero Audio Duoza ZH-DWX10, though neither ranks well in its class. It ranks #428 of 450 in-ear headphones by sound quality, rated 2.1/5, at $89; the BASN Bmaster ranks #429, rated 2.0/5, and costs $91.99, which makes this an easy call rather than a real tradeoff. Both are rated below 3.0/5 among the 450 in-ear headphones; for better sound, the Intuaura Reference 2019 ranks #5 at $34.99.
Why pick the Zero Audio Duoza ZH-DWX10: A dual dynamic driver design at 20 ohms and 100 dB/mW plays at good volume from a phone. The tradeoff: A preference score of 51 in crinacle’s measurement places it well off the response most listeners prefer, so expect a clearly colored sound.
What the BASN Bmaster does well: The hybrid driver setup pairs two dynamic drivers with a balanced armature, and the wired connection means no battery or pairing to manage. Watch for: Presence from 3 to 6 kHz runs about 8.8 dB under target, with a 9.5 dB dip near 4 kHz, so vocals and guitars lose bite and sound recessed.
Buy the Zero Audio Duoza ZH-DWX10. It is rated higher for sound quality than the BASN Bmaster and costs less, which makes it the one to get unless you need something the other one does better.

Zero Audio Duoza ZH-DWX10: $89.00 Amazon eBay
Pros: A dual dynamic driver design at 20 ohms and 100 dB/mW plays at good volume from a phone. Its rating matches the 1MORE Penta Driver for less money and sits above the Etymotic ER3SE and KZ ASX, which cost more.
Cons: A preference score of 51 in crinacle’s measurement places it well off the response most listeners prefer, so expect a clearly colored sound. Better tuned in-ears are easy to find for similar money.

BASN Bmaster: $91.99 Amazon eBay
Pros: The hybrid driver setup pairs two dynamic drivers with a balanced armature, and the wired connection means no battery or pairing to manage. In HypetheSonics’ measurement bass sits about 2.6 dB above the Harman target and sub-bass is close to target, so the tuning suits listeners who want a warm, bass-forward sound. It also rates higher than the 1MORE Quad Driver at a lower price.
Cons: Presence from 3 to 6 kHz runs about 8.8 dB under target, with a 9.5 dB dip near 4 kHz, so vocals and guitars lose bite and sound recessed. Treble and air are also down by roughly 3.7 dB and 8.1 dB, which leaves cymbals dull and the overall sound closed in. The preference score of 49 is well below what most listeners prefer.
