Pros: A broadly balanced tuning with a preference score of 75 against the Harman target.

Cons: About 3 dB less bass than the Harman target below 150 Hz, which can sound thin on pop, hip hop and electronic music. An uneven response, 1.9 dB standard deviation from target.

Is the TINHIFI C0 right for you?

Buy it if

Frequency Response

How the TINHIFI C0 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 8 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.
