Waterfi 100% Waterproof MP3 Player Swim Bundle- iPod Shuffle 4th Generation 2GB for Underwater Swimming & Water Sports + Waterproof Headphones and Mounting Straps Included - No Case Needed -
Have 6 sons who are all swimmers and bought 2 of them the Ipod Shuffle System for Christmas.  Boys love them and have been using them daily for their workouts.  However, currently have an issue with one of the systems that does not want to charge.  Waterfi has been contacted and replied and I am sure the issue will be resolved.
