Okay, so I've been using these PSIER bone conduction headphones for a couple of weeks now, and I gotta say—they’re pretty rad. First off, the fact that they’re waterproof (IPX8!) means I can finally listen to music while swimming without worrying about ruining them. Took them for a dip in the pool, and they held up perfectly. No weird disconnections or muffled sound—just crisp tunes underwater.

The dual Bluetooth + MP3 mode is a lifesaver. Sometimes I don’t wanna lug my phone around, so I just load up the built-in 32GB storage with my favorite tracks. Switching between modes? Super easy—just double-click a button. The battery life is solid too—8 hours is more than enough for my swim sessions and gym time.

Comfort-wise, these are a dream. The open-ear design means I can still hear my surroundings (super important when running outside), and the silicone cushions are soft AF. They stay put even when I’m sweating buckets or doing burpees. Plus, the adjustable rope ensures a snug fit for any head size.

Sound quality? Surprisingly good for bone conduction tech! The 14mm drivers deliver decent bass and clarity, though audiophiles might nitpick. Calls are clear too, thanks to the built-in mic.

Only gripe? The shuffle function on MP3 mode is kinda wonky—it repeats songs instead of cycling through them properly. Also, the magnetic charging cable feels a bit fragile (heard some folks had issues). But overall? 9/10 would recommend!
