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 – without the need for an amp – and still enjoy clear, precise audio across the spectrum. Swivel folding 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. Only featured with the MDR-ZX110AP model. Wide frequency range for clear highs and lows The wideband frequency range – spanning 12Hz 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. 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. 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.
