I have been swimming regularly with the WF-SP900 for 8 months. They just work great underwater. They don't have a noise-cancelling function, but they isolate outside noise well. And they have an ambient sound feature to help you hear the surround sound when you need it. The playback time needs improvement, but I'm happy with its overall performance.
