Yet the headphones also maintain vocal clarity for a wonderfully rich, well-rounded listening experience. Noise Cancelling technology
Shut out the world and enjoy your own party for one with digital noise cancelling plus EXTRA BASS sound quality. How it works
A small microphone inside the headphones collects ambient sound (traffic noise, for example) and noise cancelling circuitry analyses its signal waveform (A). The headphones then generate an inverted waveform that is the exact negative of the ambient sound (B). By overlaying the original sound with the inverted sound (C), they neutralise each other – so the only thing you hear is your music. Enjoy wireless freedom with NFC and Bluetooth® technology Near Field Communication (NFC) and Bluetooth® wireless technology remove the need for wired connections and complex set-up sequences. Simply touch your NFC-enabled device to the headphones for a quick, seamless connection, then start streaming your music collection. No NFC? No problem. Connect via Bluetooth and you’re ready to go. 
Wireless streaming with a Bluetooth® connectionWirelessly stream your favourite tracks with Bluetooth® wireless technology, by pairing your smartphone or tablet. 
NFC™ One-touch for instant connectivity Touch selected NFC™-enabled devices to the on-body N-mark for a quick, seamless Bluetooth® connection.
