Optimised as travel headphones and equipped with active noise cancellation, the AKG N700NC Wireless headphones produce crystal-clear studio sound free of distortion and distraction. The 90-degree rotatable ear cushions with memory foam provide a high degree of wearing comfort over many hours. At the push of a button, users can turn off the noise cancellation and perceive ambient sound, enabling them to listen to announcements or receive phone calls. The headphones may be folded up and conveniently stowed away in a travel bag.
