#634 Unique Melody MEST Jet Black: $1,999.00 HiFiGo $1,999.00 eBay
Pros: A flagship in Unique Melody’s MEST family, combining dynamic, balanced armature, electrostatic and bone conduction drivers. Measurements show bass right on the Harman target and full sub-bass to 20 Hz (score 68 across four measurements).
Cons: Treble sits about 3.7 dB below target, a dark, relaxed balance. A 2.41 dB spread from the target shows peaks and dips that better tuned sets avoid. Very expensive for its rating.
Is the Unique Melody MEST Jet Black right for you?
Buy it if
- you are sensitive to bright or sharp treble (treble sits 3.7 dB below target).
- you want sub-bass rumble that reaches down to 20 Hz.
- 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 $1,975 less.

- Reviews, Comparisons and Sound Samples
Frequency Response
How the Unique Melody MEST Jet Black 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 4 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 4 measurements from the squig.link databases of atechreviews, silicagel, sl0the and superreview. Thanks to each of them for publishing their work.
