The AKG HSC271 professional over-ear, closed headset is a standard for intercom, ENG/EFP work and video production. It is based on the successful K271 MKII Studio headphones combined with a high-performance condenser microphone. The flexible microphone arm mutes the microphone automatically as it is moved up. The microphone can be mounted to the left or right side, depending on personal preference and available space. The HSC271 features a switch in the headband that mutes the audio just as soon as the headphones are taken off. The high-quality six-pin mini XLR connector allows quick replacement of the cable.
