The SENNHEISER's HMD27 professional broadcast headset (No Cable) is a closed, circumaural ear-cup design with high-passive attenuation that is lightweight and pleasant to wear for long periods of time. Broadcasters and audio engineers can utilise it to get the best possible broadcast quality, even in noisy surroundings. This audio monitoring headset contains soft earcups, swivelling ear covers for single-sided listening, and a dynamic microphone that can be worn on either the right or left side. It also has ActiveGard for noise protection against noise peaks above 110 dB. A headband cushion that transforms the two-piece headband into a single compact one is also included.
