Ranked #57 of 238 in In-Ear Headphones - Symphonium Audio Helios: $1,099.00 Headphones.com eBay
Pros: One of the smoothest in-ears measured, with a 1.57 dB standard deviation from the Harman target and a preference score of 80. Bass reaches all the way down, sitting only 1.3 dB under target at 30 Hz, so kick drums and synth bass keep their rumble from an all balanced armature design. Overall tilt is essentially flat, and listeners who like a warm, bass-forward balance are the best match. It earns a higher rating than the SoftEars Twilight and the HIFIMAN RE2000.
Cons: The presence region from 3 to 6 kHz sits 3.5 dB below target, with a 6.3 dB dip near 6.95 kHz, so vocals and guitars lose a little bite and detail. The ThieAudio Monarch MKIII costs about the same and carries a higher rating.

Ranked #140 of 238 in In-Ear Headphones - 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.
