It can be annoying when water moves the ear phones and causes the music to go quiet every now and then as it disrupts your swimming flow.
My ear was a little sore after but that may have been because I was fiddling around with it so much
There is no shuffle option.
When it isn’t causing any problems it is great to help with endurance, before I knew it I had swam for 45 minutes
Having music is really enjoyable it also blocks out other noise from the pool.
Easy to use. Just a simple button press for on and off and easy music transfers.
Overall I would say it is a great product. There could be some improvement but for £50 I think it does a pretty good job in helping me get over my boredom.
