This is an awesome mp3/mp4 video player. The screen pixel density is amazing and videos look great. Battery life is great (watched 3 movies in a row without battery issues).

The bluetooth headphones included are great with being able to connect to mobile phones and pcs, but they cut into the backs of my ears....they are so uncomfortable!

I've had this mp3 player about a month now and the first thing i want to say is wow! I bought it so i could go running with no messy wires getting in the way and the bluetooth earphones just sit on your ears and around the back of your head and doesn't move when running. the sound quality is crystal clear on the bluetooth earphones as well and the fact you can control the volume, play/pause, fast fwd/rwnd all on the bluetooth earhones is great. They are also pretty resistant to sweat as the sponge ear piece soaks it up quite well ( let it dry out afterward though). oh and you also get a nice wired set of earphones that fit snuggly in your ear. battery life is brilliant for such a small bit of kit and the bluetooth earphones battery lasts a very long time as well. In my opinion much better than what Apple offer.

I have had a few mp3 players over the years, almost as if I have been searching for the ultimate one, I decided to give the Sony NWZA828KB a try out and I was not disappointed, the sound from this unit is brilliantly crisp and clear, there is enough volume on this thing to satisfy all users, the menus are well layed out and easy to use, once charged and connected to the pc I had all my music on it within 15 mins and was walking around the house with the bluetooth headphones on which by the way are excellent, I tried the bundled software (after upgrading it - cost £7 online) to convert a couple of features films (aliens & hostage) and they play perfect, so if your looking for an mp3 player get this Sony you will not be disappointed trust me.
