The AKG HSD 171 professional headset from AKG has been designed for broadcast and recording use. In addition to excellent comfort, optimum ambient-noise attenuation, and outstanding audio quality, the HSD Series professional headsets use the same proven detachable cable as the Studio Series headphones. So should a cable become defective under the enormous stress of day-to-day broadcast work, it can be replaced quickly and without any tools. The flexible microphone arm on the HSD171 swivels through a 270-degree arc and mutes the microphone automatically as you move it up – no need to fumble for a mute button! Also, you can wear the microphone to the left or right of your mouth depending on your preferences or available space. Commentators, off-camera moderators, camera operators, or sound engineers - AKG professional headsets are always the perfect tools for any application in professional audio and satisfy every user’s personal preferences.
