#635 QoA Martini: $539.10 Linsoul $539.10 eBay
Pros: A six driver tribrid with a bone conduction driver, a dynamic driver and four balanced armatures. Measurements show bass right on the Harman target and full sub-bass to 20 Hz (score 68 across five measurements).
Cons: Treble sits about 4.7 dB below target, a dark, relaxed balance. A 2.32 dB spread from the target shows peaks and dips that better tuned sets avoid. Expensive for its rating.

Buy it if
- you are sensitive to bright or sharp treble (treble sits 4.7 dB below target).

Skip it if
- you want the best value: the higher-rated EPZ G10 costs about $515 less.

Frequency Response
How the QoA Martini 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 bassaudio, hu-fi, joycesreview, pw and soundcheck39. Thanks to each of them for publishing their work.
