The player does exactly what I bought it. Plays music in good quality with a swim. Unpacking is somewhat difficult since Sony has designed the packaging maximum complicated. Something like the opposite of Frustration-Free Packaging Amazon. But as the unpacking is needed at the beginning only once there is no penalty for it. The player itself sees only times good, does not weigh too much and is easy to install. The included "dock" the player is connected via USB to the computer for music transfer and charging. In Windows 8, the player is automatically set up and it can be copied music via drag-and-drop immediately. To Carry: While wearing should pay attention to the correct size of earplugs because too large or too small pegs can ensure that the player is not in place and so that's going swimming or water coming into your ears. For me, the player remains in the crawl way, just sit right if I have a bathing cap to to. The hood also need not be completely pulled over on what would probably exert too much pressure in the long run, but it is sufficient if the strap from the player are over your ears covered. Then can also be easily more than an hour with the player swimming without water in the ear, loss from the player, or too hard. To operate: I think the operation intuitive and easy. Since there is no display makes the player sounds when it is turned on / off and says once turned what function has been activated (start / stop, Shuffle, etc). In order for the various buttons and blind can be operated at the toggle switches are small "dot" attached that can be well sensed. But up to now and then turn a song more or change the volume I need no functions. If you want to exhaust all the functions (Shuffle, etc) but you should perhaps read the instructions and make a few dry runs. Overall, therefore, as I said a good player of the job.
PS: The first delivery has been switched off after an hour ago and no longer wanted to swim, but this can happen in all products I think times. Amazon has a new sent the already with me was before I was able to get time at all to dismiss defective. The replacement now works fine for 3 months.
