Featuring inverse phase active technology which cancels out background noise and high quality protein leather ear pads, the NC60s reduce external noise by up to 85% resulting in a more enjoyable audio experience. The 40mm driver units provide superior sound performance whilst the soft, cushioned earpads are comfortable to wear for long periods. Perfect for on a long flight, train journey, in the car or just to use at home. For added convenience the NC60 earpieces can be rotated so that the headphones can be stored flat in the included durable vinyl carry case, saving you precious space in your hand luggage whilst keeping the NC60 protected. In addition to the flexible 1.5m audio cable, adapters for connecting to dual plug inflight entertainment systems and your HiFi are included.
