Works great, easy to use.

It works very well! Wasn’t set up and use. Lots of choices for ear pads. Such a changer to swim with music!

Listening while swiming

I use this device every day. I swim (very slow) everyday for 100 min and this allowed me to do audio books in this device. I would be bored if I didn’t have this or music.
