Sennheiser HMD 300 Dual-Sided Broadcast Dynamic Super-Cardioid Microphone Headset

The Sennheiser HMD 300 Dual-Sided Broadcast Dynamic Super-Cardioid Microphone Headset ensures clear communication, especially in noisy backstage settings. Featuring a closed circumoral design, they provide a frequency response ranging from 60 Hz to 25 kHz for precise audio reproduction. ActiveGard limiting technology protects against abrupt audio spikes. These headsets come with a dynamic boom microphone that has a super-cardioid polar pattern and structure-borne noise isolation, allowing for versatile wear on either side. Additionally, a split headband design reduces pressure, ensuring comfort during extended periods of use.

Key Features
