HME 27


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 HME 27 presents broadcast commentators and audio engineers with professional broadcast headsets featuring Sennheiser’s highest audio quality and comfort level. Remarkably lightweight construction is ideal for long work hours, and a pre-polarized condenser microphone with cardioid pick-up pattern delivers the pristine broadcast quality your work demands.
