#503 Unique Melody Stardust: $799.00 HiFiGo $799.00 eBay
Pros: A six driver hybrid with two dynamic drivers and four balanced armatures in a 3D printed titanium shell. Measurements show bass right on the Harman target and full sub-bass to 20 Hz (score 71 across seven measurements).
Cons: Treble sits about 4.3 dB below target, a dark, relaxed balance. Expensive for its rating.

Frequency Response
How the Unique Melody Stardust 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 7 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 7 measurements from the squig.link databases of atechreviews, elrics, jaytiss, silicagel, sl0the, tonedeafmonk and zerostresslevel. Thanks to each of them for publishing their work.
