At first glance the Parrot Zik are just super-comfortable, beautifully retro over-the-ear Bluetooth headphones: Once the headphones are connected to your phone (there's a mic inside, so you can use it to make calls too), all playback control is done by gestures — slide your finger up or down on the headphone to change the volume, or swipe forward to change tracks. If you take the headphones off your ears, an accelerometer notices and automatically pauses your music; put them back on, and it starts playing again. There's even NFC connectivity, so you can tap your phone to the headphones to connect.
