Short answer: the Sennheiser IE 600. Both are rated 3.5/5 for sound quality (#357 and #352 of 450 in-ear headphones), and the Sennheiser IE 600 costs $699.95 against $899 for the Symphonium Audio Triton, with sound quality a draw, the lower price decides it.
What the Sennheiser IE 600 does well: Sub-bass extends to 20 Hz with a slight 1.7 dB lift, and bass, low mids and upper mids all sit within about 1.3 dB of target, so the core of most music sounds full and natural. The tradeoff: In oratory1990’s measurement a 7.6 dB dip near 5.9 kHz and a presence band 5.5 dB under target take bite out of vocals and guitars, while a 4.7 dB peak near 9.7 kHz can sound sharp.
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.
Buy the Sennheiser IE 600. Both are rated the same for sound quality, and it costs $199.05 less than the Symphonium Audio Triton.

Sennheiser IE 600: $699.95 B&H Photo Video eBay
Pros: Sub-bass extends to 20 Hz with a slight 1.7 dB lift, and bass, low mids and upper mids all sit within about 1.3 dB of target, so the core of most music sounds full and natural. Air above 10 kHz is lifted about 5.6 dB, adding sparkle to cymbals and room sound. At 118 dB/V it is easy to drive from a phone, and it suits listeners who like a bassy or warm tilt.
Cons: In oratory1990’s measurement a 7.6 dB dip near 5.9 kHz and a presence band 5.5 dB under target take bite out of vocals and guitars, while a 4.7 dB peak near 9.7 kHz can sound sharp. The FiiO FD5 and iBasso IT04 both carry higher ratings for considerably less money.

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.
