#637 Tin HiFi P2 Ultra: $599.00 Amazon $599.00 eBay
Pros: A 12mm planar IEM with a gold plated shell. Measurements show bass right on the Harman target (score 68 across five measurements).
Cons: Treble sits about 4.7 dB below target, a dark, relaxed balance. A 2.47 dB spread from the target shows peaks and dips that better tuned sets avoid. Expensive for its rating, and a low 98 dB sensitivity needs more volume.
Is the Tin HiFi P2 Ultra right for you?
Buy it if
- you are sensitive to bright or sharp treble (treble sits 4.7 dB below target).
- you are happy to use EQ: our preset lifts its Harman match by about 23 points.
Skip it if
- you want the best value: the higher-rated EPZ G10 costs about $575 less.

- Reviews, Comparisons and Sound Samples
Frequency Response
How the Tin HiFi P2 Ultra 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 5 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 5 measurements from the squig.link databases of atechreviews, audioamigo, csi-zone, ducbloke and soundignity. Thanks to each of them for publishing their work.
