HMD 27

Article No. 700322

The HMD/E/C 27 professional broadcast headsets are meticulously tailored for commentators and audio engineers who demand the highest levels of audio performance and ergonomic comfort. These closed, circumaural headsets feature ActiveGard© limiting technology to protect your hearing and microphone options like a pre-polarized condenser capsule or a dynamic capsule, depending on your application. At the same time, their lightweight build, soft earpads, and innovative two-piece headband offer pressure-free wear. Furthermore, the HMDC 27 also includes switchable NoiseGard™ technology for operating in the noisiest environments.

The HMD 27 professional broadcast headset provides the finest audio quality and long-term comfort, even in noisy environments. Combining the benefits of a closed-back, circumaural earcup design with ergonomic, lightweight construction, the HMD 27 is perfect for broadcast commentators and audio engineers working long hours. Along with ActiveGard© limiting technology with three switchable attenuation settings that protect you against sudden audio peaks, you will find a work-ready dynamic microphone that can be worn on either side.
