HMD 300


The ergonomic HMD 300 professional broadcast headsets excel in the energy and volume of backstage broadcasting environments. Featuring a comfortable, closed circumaural design, switchable ActiveGard© limiting technology, reduced structure-born noise, and a dynamic boom microphone that can be worn on the right or left side, they provide ideal performance at an exceptional value.

The HMD 300 broadcast headsets offer clear communication, even in high-volume backstage environments. A closed circumaural design offers a frequency response of 60 Hz to 25 kHz for clear audio reproduction, while ActiveGard© limiting technology intelligently shields against sudden audio bursts. A dynamic boom microphone combines a super-cardioid polar pattern and structure-borne noise decoupling with the flexibility to be worn on either side, while a split headband alleviates pressure for long-term use.


  • Dual-sided earcup design ideal for noise isolation and enhanced immersion applications
  • Comfortable, single-sided design ideal for dynamic communication environments
  • Dynamic super-cardioid microphone for clear communication in noisy environments
  • Switchable ActiveGard© limiting technology for protection of noise peaks <110 dB
