#636 QoA Adonis: $181.00 Linsoul $181.00 eBay
Pros: A hybrid with a 9.2mm dynamic driver and two balanced armatures. Measurements show bass and treble both within 1 dB of the Harman target (score 68 across three measurements).
Cons: A 2.44 dB spread from the target shows peaks and dips that better tuned sets avoid. Linsoul sells a revised Adonis New, and it is not confirmed whether it matches the tuning measured here. Its score rests on three measurements.

Frequency Response
How the QoA Adonis 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 3 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 3 measurements from the squig.link databases of practiphile, soundcheck39 and timmyv. Thanks to each of them for publishing their work.
