Sony ZX220BT Wireless Headphones    
    
FEATURES    
Wireless streaming with Bluetooth®    
Wirelessly stream your favorite tracks with Bluetooth®. Pair your smartphone or tablet with these Bluetooth®-enabled headphones, and you can enjoy your music and even control playlists and volume right from your device.    
    
NFC One-touch for instant connectivity    
Near Field Communication (NFC) technology makes complex set-up sequences a thing of the past. Simply touch selected NFC-enabled devices to the on-body N-mark for a quick, seamless connection, then start streaming content over Bluetooth. No NFC? No problem. You can still manually connect to Bluetooth using your device’s settings menu.    
    
Hear it all with 1.18 in drivers    
Hear more of the detail in all your favorite songs thanks to 1.18 in dome drivers, which deliver dynamic sound from compact, lightweight units.    
    
A built-in microphone for hands-free calls    
Take calls and issue voice commands — even with your phone secure in your pocket or bag. And with a high-quality inline microphone, you'll be able to make and answer calls from your smartphone with ease.    
    
Swivel folding design makes travel easy    
Take these headphones anywhere you go. A swivel folding design makes it easy to store them when not in use or while traveling. The earcups swivel flat to slip easily into a suitcase or bag.    
    
Listen longer with 8 hours' wireless playback    
Keep your tunes playing throughout the day. A built-in Li-ion battery delivers approximately eight hours of power (depending on your music settings2), and is rechargeable via Micro USB.
