AKG HSD 271 mkII

Overview

The HSD271 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 rugged dynamic 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 HSD271 features a switch in the headband that mutes the audio just as soon as the headphones are taken off. The plug-in cable with a six-pin mini XLR connector allows quick replacement of the cable.
