#1070 TRI i One: $179.00 Keephifi $179.00 eBay
Pros: A single 10 mm carbon dynamic driver with full sub bass to 20 Hz and bass about 3 dB above target, giving a full, punchy low end. Presence from 2 to 5 kHz sits right on target, so vocals come through clearly, and 108 dB sensitivity runs from a phone dongle.
Cons: Treble falls away above 5 kHz, about 3.5 dB low from 5 to 8 kHz and 5 dB low from 8 to 12 kHz with an 8.5 dB dip near 10.9 kHz, so it lacks air and sparkle. The Truthear Nova scores far higher at a similar price.
Is the TRI i One right for you?
Buy it if
- you like extra bass (about +4 dB below 150 Hz versus the target).
- you want sub-bass rumble that reaches down to 20 Hz.
- you are happy to use EQ: our preset lifts its Harman match by about 24 points.
Skip it if
- you want the best value: the higher-rated EPZ G10 costs about $155 less.

Frequency Response
How the TRI i One measures across the audible range, against the Harman in-ear target that most listeners prefer in blind tests. Where the line sits above the target that range sounds louder (more bass, brighter treble), below it quieter. The curve is the median of 4 independent measurements, so one odd sample or rig cannot skew it, and both lines are shifted so their 500 Hz to 2 kHz average sits at 0 dB.
Measurement data: median of 4 measurements from the squig.link databases of achoreviews, cqtek, fahryst and pw. Thanks to each of them for publishing their work.
