This is my second headphones that I swim with almost every day.I have only had these headphones for a short time but they are a great improvement over the first generation. The headphones stay in my ears, have great sound and are comfortable. The one thing I do not like is that the cord is too long. I had to knot it loosely in order to shorten it up. It would work better if the whole cord was a coil rather than having so much straight cord.
