Usually one of them doesn't work while swimming and the battery doesn't last more than 6 hours no matter how long you charge it.

Headphones worked pretty well, but my Bluetooth with my ipod wouldn't work under water.  Kind of a bummer, but they worked well for messing around in the pool and I could leave my ipod away from the water

I have purchased two of these.  I love how they work Anx that they are the only ones you can wear swimming and in the shower. But both of one have popped out of the sport wristband multiple times and eventually got lost.

Researched for a waterproof headphone set because Im a swimmer and I tend to get bored just swimming laps in silence. I tried them out today and as soon and I got in the water they shut off. I was upset but decided to just keep them since they were Bluetooth and I can use them at the gym. I just tried them again after they were done drying and only one ear piece has sound now. On the bright side their customer support was extremely helpful.

They are great except one of them don't work. Im not going to return the whole thing just due to 1 not working. If i knew how to contact the seller id ask for a replacement.

Bought two of these, one of which the ball in the tube sometimes gets stuck up in causing my birds to not have access to water. That would be very worrisome if I did not have a backup.

Units are working but one seems to not recharge well during our cloudy days. Waiting for snow to see if they will repel any varmints. We have a problem with  coons,mink,fox, coyotes, opossum, horned owls and red-tail hawks so we'll see . If they work Ill be ordering more

They look great ,but one of them does not work. The tip came off and it is too difficult to get back on.
