Freedom from noise and wires
Listen without wires and block out unwanted background noise — just hear your favorite music with digital noise cancelation.
Noise canceling made for travel with One Push
Artificial Intelligence Noise Cancelation (AINC) analyzes background sound and adjusts it for optimal performance on airplanes and other noisy environments. Just press and hold the NC button on your headphones to activate it.
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 via Bluetooth® connection. No NFC™? No problem. You can still manually connect using your device's settings menu.
Wireless streaming with Bluetooth® connection
Wirelessly stream your favorite tracks with a Bluetooth® connection. Pair your smartphone or tablet with these Bluetooth®-enabled headphones. You can even start your music, skip tracks and control volume directly on the headphones without touching your device or removing it from your pocket or bag.
Listen all day, charge up quickly
Keep your music playing all day. A built-in Li-ion battery delivers up to 35 hours of power (depending on your music settings) and is rechargeable via USB. Quick Charging gives 60 mins of play back from 10 minutes of charge.
Hear everything with 40 mm drivers
Get more from your music thanks to 40 mm dome drivers that deliver deep bass and a wide frequency range.
DSEE restores detail to your digital music
Boost the quality of your compressed music files. When an original music source is compressed, it loses the high-frequency elements that add detail and richness to your favorite tracks. The Digital Sound Enhancement Engine (DSEE) faithfully restores these to produce a high-quality sound that's closer to the original recording.
