Also supplied is a software to load the MP3 player with music, this is optional, but I personally find it very comfortable to copy, is a matter of taste.
Charging is done quickly (under two hours) and then you can start already. The main function of the 3 in 1 is the wireless MP3 players because of the freedom of movement granted, you do not care to get stuck somewhere for me.
The rotary receiver are well padded and can be easily adapted to any head size, tight and even after several hours, they are not annoying or even painful. The unit offers many possibilities such as Zappin (short audio samples), Shuffle, jumping between tracks and folders etc. Even without the display you find yourself along well, I do not miss. Although the service is initially used to, but once you get the hang of only times they succeed without problems.
I ground myself not to, to have perfect pitch and am more than satisfied, in marked contrast to cheap products to the rich full sound. The battery lasts forever, I have not had to charge him so far and the available 14GB memory enough for me just fine. Prima works of soundproofing that sometimes annoying environment can be hidden comfortable.
Of course you can the device as headset use (with cable) for Smartphone, etc., which I personally prefer to use here in ear earphones. Not quite reveals itself to me the sense of surround speakers, why should I for anything in the world to me the headphones around your neck and therefore sonication the environment? But okay, maybe so can indeed be won a younger target group.
Conclusion: The Sony is really fun and is a very short time become one of my favorite devices for listening to music.
