Okay, so I've been using these PSIER bone conduction headphones for a couple weeks now, and I'm OBSESSED. Here's the tea:
First off, the open-ear design is a game-changer. I can hear my coach yelling at me during swim practice while still jamming to my pump-up playlist. No more awkward 'huh?' moments mid-lap!
The waterproofing is LEGIT. Took these bad boys for a 2-hour pool session (yes, I timed it) and they survived my terrible butterfly stroke attempts. The MP3 mode means I don't have to worry about my phone getting wet - just load up songs like it's 2005 again.
Comfort? 10/10. The silicone pads feel like little clouds hugging your face. Did a full triathlon training day (swim-bike-run) and forgot I was wearing them half the time.
Only gripe? The shuffle function needs work - heard 'Mr. Brightside' three times in one session (not that I'm complaining... much). But for underwater tunes and situational awareness, these are worth every penny!
