Digital Noise Cancelling for less distractions

Digital Noise Cancelling reduces a variety of ambient noise when listening to music. A microphone built in to the headphones works with the digital noise cancelling engine to cut out unwanted sound. The headphones select the optimal mode (aeroplane, train or office) based on an intelligent analysis of the environment. Activate or deactivate noise cancelling using the on/off switch.

Neodymium dynamic drivers deliver precise sound

Lightweight 40mm neodymium dynamic driver units enable the headphones to deliver a punchy, rhythmic response to even the most demanding track. Combined with a highly sensitive diaphragm, you’ll be able to turn the headphones up louder and still enjoy clear, precise audio across the spectrum.

Tight bass with Beat Response Control

Beat Response Control technology delivers tight, deep bass response, making it perfect for low-end focused music styles. An air vent maximises airflow within the low frequency range, optimising the efficiency of the diaphragm to enable more accurate reproduction of bass rhythms.

High sensitivity for a loud, clear sound

With a high sensitivity of 100dB/mW when using the audio cable (98dB/mW with noise cancelling on), these headphones are highly efficient in converting electricity into acoustic signals. This means you’ll hear a louder sound across the entire audio spectrum (compared to less sensitive headphones) when listening to music through the same source and at the same volume level.  

Take calls hands-free with built-in mic

Whether you’re chilling in the living room or lounging in the garden, when a call comes in, you won’t need to touch your phone. Simply pair your phone with the headphones via Bluetooth, and use the built-in microphone to chat away.

Support for popular AAC and aptX codecs

These headphones support popular, high quality codecs, including AAC for iPhone/iOS users, and aptX® for pure wireless sound that doesn’t compromise on audio quality. The aptX® codec enables pure wireless audio to be sent wirelessly over Bluetooth by reducing the size of audio files.
