The K271 MKIIs are professional over-ear headphones for studio and live use. They combine the comfort of an over-the-ear design and the benefits of closed-back technology for best possible sound reproduction. The sealed design ensures low signal bleeding into microphones in the studio and maximum isolation for live mixing applications.The K271 MKIIs feature a switch in the headband that mutes the audio just as soon as the headphones are taken off. They provide a professional mini XLR connector for quick replacement of the cable. The package includes a 3m (10ft) straight and 5m (16ft) coiled cable.
