Professional Headset/Microphone with Single-Sided Closed-Back Circumaural Headphone


These professional headsets from AKG have 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 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.

HSD 271 Single: the HSD 271 is also available in a special version with a single earphone, see "More product pictures". This model is the perfect choice for all jobs where the user needs to listen to natural sounds as well as those coming through he headphones.
