Hang on

Clips on and hangs tough through all your tricks, flips and whatever. What can we say; who likes 

earbuds falling out.

Sound

Crystal clear sound right in your ear. Soft earbuds and 9MM drivers combine for a comfortable 

and snug fit that delivers clear sound to your inner ear. 

Go anywhere

Hook’em anywhere you like, so you can take them everywhere you go.
