User reviews

Can’t register

This app is horrible, why do you need to register for a app to control ear buds it’s ridiculous. Either way it won’t send me a verification code so I can register so it’s literally useless.

Garbage

Wants a 6-20 character password, which I’ve given it. So useless. Can’t do anything with it. Junk that lets down not bad earbuds.

Worst headset I've ever bought

It barely works, when it's in physical activity it changes the music and even turns it off because of the sweat. Terrible, horrible. And the app doesn't even work.
