I buy this gift for my brother player for practicing swimming, but it is very tight: a receipt of the product, this one was DEFECTIVE: the battery had a battery life of 30 minutes (for information that is normally prévut hold about 10 hours), so I contacted the company to operate the guarantee after two weeks not response. I made the call AZ guarantee amazon and there magic in 3 days in j get another brand new (international via fedex) But after 8 to 9 months of use the battery only holds 3 hours. thus has a 150 player holding 3 hours and although there is cheaper.
