4 Jabra Revo Wireless.
No wires doesn't mean compromised sound quality. With Revo Wireless headphones, it means freedom of movement and massive sound that doesn't skip a beat. Turntable Touch Control allows you to easily play, skip or pause your music and manage calls. Hear and be heard with clear calls, tap to pair with NFC and keep your tunes going with long playback. Designed to be used and abused, Revo Wireless is solidly built with an aluminum frame, steel hinges, and a shatterproof headband for extreme flexibility. Drop, bend and fold-tested to the max to ensure it can take whatever life has in store. Hard to the core and soft to the touch--Revo Wireless headphones are super comfortable with a padded headband and plush, memory foam ear cups.
