General
This blue edition of Sony's comfortable, wireless MDR-ZX550BN headphones produces crystal-clear sound, and has a practical noise cancellation button that allows you to quietly enjoy your favourite music without being bothered by your surroundings. Connecting the headphones to your smartphone, MP3 player or tablet is incredibly easy thanks to NFC (Near Field Communication) technology. Simply hold them up against your music player for a moment, and a wireless link is automatically established. If your device doesn't support NFC, there's no need to worry. You can also set up a connection via Bluetooth.
25 hours of wireless music
Once the battery of your Sony MDR-ZX550BN headphones is fully charged, you're free to listen to the music you love for up to 25 hours. Even during long listening sessions, the comfortable, soft ear pads will make you lose track of time.
