I just got the new Sony Walkman Unwired and its excellent man, started using the same to keep me distracted while jogging in the morning and this is what I now understand are the advantages.
Unwired: I realised this today when I saw a guy running with a big iPod in his hand with the wire running from his hand to his ear while bouncing around. I think I felt some jealousy there. I now realise the bliss of running unwired.
Fits easily in the ear: This is the reason for me buying this lovely gadget, I used another walkman eaelier with the wired earphones, and it kept slipping out from my ear and made me to slow down to get it back in the ear. I decided to go in for the unwired. and this beauty does not move while you may do whatever.
Sound Quality: Is truly amazing its superb, the bass and trebel are both loud and clear. equaling tThe best you can get in any ipod or walkman.
Charging: I love express charge, in case you forget to charge it in the night, just plug it in the USB for 3 mins and it is ready to play music for 90 mins. Brush your teeth and in the meanwhile the player is ready.
I really wish that there were a few more features on this device like recording and FM tuner, but then this designed for use while ebgaged in physical activities. Anyways, I can still use my phone for recording my own songs.
My suggestion: Its cool, go for it, you will love the music on it and dont be surprised if people stare at you as if you were an alien.
