Dude it comes with its own app that has its own sounds like when you dont fancy music you can just have a moment of serenity with birds singing or listening to rainfall or both, yeah you can mix all the sounds that are available together. This is awesome.
I like app. There is the selection of the background noise to play. Hold well around ear. Little cheap plastic feeling for case. Excellent t battery live 14h and 60 with case.
