content: It's an mp3 player that does not play mp3s.Mine does not play at all. No sound. Nothing.I hooked it up to my computer, dragged over the mp3 files, then connected the headphone to the strap and the strap to the key ring play and clicked play and nothing.You really don't have any clue what the device is doing. It's impossible to tell if it's charged or not.It comes with a AAA attachment charger that doesn't seem to help anything because again there's no screen and there's no way to tell what it's doing. You just press play over and over and over and wonder why there's no sound.You can't connect your headphones straight to the device. Instead you must use the neck strap for controls.Since mine doesn't make any noise at all (although it does store files) I can not recommend this product.Oh and the instructions that come with it are HORRIBLE!
