Beat Response Control for tight bass

Beat Response Control technology delivers a 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.

Swivel design makes travel easy

Take these headphones anywhere you go. The headphones’ swivelling earcup design enables easy storage when you’re not using them, and enhances portability when you’re travelling. The earcups swivel flat, so you can pack them into a suitcase or a bag without worrying about them taking up too much valuable space.

In-line remote and mic for hands-free calls

With an in-line remote and built-in microphone on the headphone cord, you can take hands-free calls from selected smartphones while listening to music. Switch easily between songs and calls with no need to remove your headphones.

Aluminium fascia for punchy bass 

These headphones are made for the kind of bass that gets you moving. The light but rigid aluminium fascia on top of the housing suppresses unwanted vibration to preserve deep, punchy, low notes.

Cushioned earpads for total comfort

Listen in total comfort. These headphones have a self-adjusting headband and soft cushioned earcups that cover the whole ear. Enjoy the long-lasting comfort you need for listening to your favourite albums back-to-back.

Neodymium dynamic drivers deliver precise sound

Lightweight 30mm 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.

Enfolding closed-back design seals in sound

The closed-back, enfolding design wraps around the ear, helping to seal in music and keep distractions out. Acoustics are reflected back towards your ears, so you hear even the subtlest of sounds. You’ll also feel every beat, as the closed-back design helps to maximise the bass signatures in your music.

High sensitivity for a loud, clear sound

With enhanced sensitivity of 102dB/mW, 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.

The wideband frequency range – spanning 5Hz to 22kHz – delivers deep bass, rich mid-levels, and soaring highs. Hear the detail in every track and stay in tune with all your music.
