Short answer: the SoftEars Twilight. It ranks #329 of 450 in-ear headphones by sound quality, rated 3.8/5, at $930. The Symphonium Audio Triton ranks #352, rated 3.5/5, at $899, $31 cheaper, which does not close the gap in sound quality.
What the SoftEars Twilight does well: Across 20 hobbyist measurements on squig.link no deviation between 1.5 and 12 kHz exceeds 3.4 dB, so the treble stays smooth and free of sharp peaks. The catch: Sub-bass trails the target by about 2.9 dB and is down nearly 5 dB at 30 Hz, so the deepest rumble in electronic and film soundtracks is lighter than ideal.
The case for the Symphonium Audio Triton: 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. Watch for: 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.
Buy the SoftEars Twilight. It is rated higher for sound quality, and the $31 you would save on the Symphonium Audio Triton does not close the gap.

SoftEars Twilight: $930.00 Amazon AliExpress eBay
Pros: Across 20 hobbyist measurements on squig.link no deviation between 1.5 and 12 kHz exceeds 3.4 dB, so the treble stays smooth and free of sharp peaks. Bass and low mids sit about 2 dB above target, giving vocals and acoustic instruments a warm, rich body. With 16 ohm impedance and 116 dB/V sensitivity it is easy to drive from a phone, and it rates higher than the Sennheiser IE 600 and HIFIMAN RE2000.
Cons: Sub-bass trails the target by about 2.9 dB and is down nearly 5 dB at 30 Hz, so the deepest rumble in electronic and film soundtracks is lighter than ideal. The presence region sits about 1.9 dB low, softening some vocal clarity, and the cheaper SoftEars RSV rates noticeably higher.

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.
