Short answer: the Symphonium Audio Triton. It ranks #352 of 450 in-ear headphones by sound quality, rated 3.5/5, at $899; the SeeAudio Neo ranks #365, rated 3.4/5, and costs $1,099, which makes this an easy call rather than a real tradeoff.
What the Symphonium Audio Triton does well: The hybrid of one dynamic driver and two balanced armatures keeps the bass and midrange close to target, with the bass band within 0.5 dB and the upper mids within 0.9 dB in squig.link measurements. The catch: Across hobbyist measurements the presence band sits 5.1 dB low with a 6.6 dB dip near 6.3 kHz, which dulls vocal edge, cymbals and fine detail.
Why pick the SeeAudio Neo: Bass and sub-bass sit within a decibel of target down to 20 Hz, giving a clean, controlled low end without boom. The tradeoff: Squig.link measurements show the 3 to 6 kHz presence band about 5.4 dB below target with a 9.2 dB dip near 5.5 kHz, so vocals lose clarity and instruments sound recessed.
Buy the Symphonium Audio Triton. It is rated higher for sound quality than the SeeAudio Neo and costs less, so only choose the other one for a particular feature it does better.

Symphonium Audio Triton: $899.00 Headphones.com eBay
Pros: The hybrid of one dynamic driver and two balanced armatures keeps the bass and midrange close to target, with the bass band within 0.5 dB and the upper mids within 0.9 dB in squig.link measurements. Sub-bass still reaches 20 Hz within 6 dB of target, sitting 2.3 dB low at 30 Hz. At 107 dB/V and 8.3 ohms it plays loud from a phone.
Cons: Across hobbyist measurements the presence band sits 5.1 dB low with a 6.6 dB dip near 6.3 kHz, which dulls vocal edge, cymbals and fine detail. Crinacle’s preference score of 68 is middling, and the SoftEars Twilight rates higher at a similar price.

SeeAudio Neo: $1,099.00 Linsoul eBay
Pros: Bass and sub-bass sit within a decibel of target down to 20 Hz, giving a clean, controlled low end without boom. Ten balanced armatures add about 3.8 dB of air above 10 kHz for some sparkle. At 116 dB/mW it gets loud from any phone or dongle. It rates higher than the qdc Anole V6 while costing less.
Cons: Squig.link measurements show the 3 to 6 kHz presence band about 5.4 dB below target with a 9.2 dB dip near 5.5 kHz, so vocals lose clarity and instruments sound recessed. Such high sensitivity can reveal background hiss from noisy sources. The DUNU Zen Pro and JVC HA-FW1500 earn the same rating for less money.
