I was excited to try it and I must say it does its job well, but with some caveats. 1. Both the volume is easily customizable, so make arbitration between too much out of the water and not strong enough under water is complicated. 2. At this price, it could have been delivered directly to the cuff. 3. The in-ear tips are too big. I personally have a very small ear pavilion and I have to fight to keep good sound on multiple lengths. With a swimming cap is better, but it could still be improved. The tips could be smaller therefore, but effort is I think especially to the side of the size headphones themselves.
