Sennheiser Hmd-300-X3K1 Headphones With Dynamic Microphone With Cable

The ergonomic professional broadcast headsets HMD 300 X3K1 excel in energy and volume in backstage broadcasting environments. They feature a comfortable, closed circumaural design, switchable ActiveGard© limiting technology with reduced structure-borne noise, and a dynamic supercardioid microphone that can be worn on either the right or left side, providing ideal performance at exceptional value.

The HMD 300 broadcast headsets deliver clear communication, even in high-volume backstage environments. The closed circumaural design provides frequency response from 60 Hz to 25 kHz for clear sound reproduction, while ActiveGard© limiting technology protects against sudden audio bursts exceeding 110 dB SPL. The dynamic boom microphone (BMD 434-300) combines supercardioid polar pattern and structure-borne noise reduction with the flexibility to be worn on either side. The split headband reduces pressure for extended all-day use, ideal for lengthy sessions. The HMD 300 X3K1 includes an XLR 3 to 6.3 mm cable that reduces structure-borne transmitted noise.
