Short answer: the Unique Melody Stardust. Both are rated 3.8/5 for sound quality (#596 and #605 of 1291 in-ear headphones), and the Unique Melody Stardust costs $799 against $899 for the Meze Astru, with sound quality a draw, the lower price decides it.
The case for the Meze Astru: A single dynamic driver IEM with bass right on the Harman target and full sub-bass to 20 Hz. The catch: Expensive for its rating.
Why pick the Unique Melody Stardust: A six driver hybrid with two dynamic drivers and four balanced armatures in a 3D printed titanium shell. Watch for: Treble sits about 4.3 dB below target, a dark, relaxed balance.
Buy the Unique Melody Stardust. Both are rated the same for sound quality, and it costs $100 less than the Meze Astru.
