Yunzhengfei Bone Conduction Bluetooth Headset MP3 Player

Right so, i was sceptical. No reviews, unknown brand, weird translations, seems like some chinese thing.Thing is, 99.999% of waterproof mp3 players use "buds". My ears cant do buds. They are physically incompatible. So after spending a few days on the internet, i can safely say that these are the ONLY non-bud waterproof MP3 player/headphones that i've found. Anywhere.So... Screw it, ordered it. And so far, i am VERY happy.The controls are minimal (as expected), and charging is done via the 3.5mm headphone jack... But you can put stuff on it just fine, and it plays.Most importantly, THEY CAN BE LOUD. An issue with a lot of mp3 waterproof players is that they are so very quiet, its impossible to hear anything. These things? no issues.I am using them in my swimming pool with an audiobook loaded in and they work perfectly (so far).

Complicated to use, unreliable, and with insufficient instructions in broken English. One can do better with this money.

Can't change the language or upload any music!

Wouldn’t recommend as they simply did not work when swimming. The sound would cut out when I would swim.
