I forget when Xiaomi put out these earphones. Launch price was 999, then all of a sudden I noticed they’d been cut in half to 499, and before long you could pick them up on eBay for 299… From 999 down to 299. These things lose value fast. And this is supposedly a kickass “dual dynamic” + “dual balanced armature” setup. Mine came from eBay, listed as brand new. What showed up was a plain box with the earphones, some spare silicone tips, and even a mysterious “Bluetooth adapter” of unknown provenance (turns out that was in the original package too, for phones without a headphone jack). The stock silicone tips are genuinely badly sized — way too big. They leak sound, which is why I kept thinking something was wrong with the sound at first. Switched to one size smaller and the problem went away.
