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.
