Hi guys, I like so much this headphone. three ways to listen to your music. with integrated wireless digital media player and built in speakers. so sound output is very violent. NWZ changes the way you listen to music. wear it or around my neck. so fitting comfortable. me and my friend also using same sony product. he asked same feeling. integrated wireless music player 4GB space so I m long time hearing music. powerful loud speakers virtualphones let share my music with friends. just a 3 minutes charge, and I can enjoy one hour playback. with a 20 hour battery life, never stop this play music
this headphone supplied headphone cable, usb cable, quick start guide. so very useful and I like this headphone. normal cost but good quality. so everbody all buy this headphone and enjoy music life.
