Sennheiser HMD 300 X3K1 Dual-Ear Around-Ear Broadcast Headset with Dynamic Mic and Cable

The Sennheiser HMD 300 X3K1 Dual-Ear Around-Ear Broadcast Headset with Dynamic Microphone is ideal for backstage communication. The lightweight design offers extra soft cushions and headband padding for long-lasting comfort during extended production days. The closed-back around-ear headphones and ActiveGard limiting technology (with three switchable attenuation settings) prioritize isolation, noise reduction, and hearing protection, while still handling high-decibel performance.

The integrated, dynamic supercardioid boom microphone gives you reliable broadcast sound quality up to 18 kHz and delivers excellent acoustic performance. Featuring a modular design, the HMD 300 X3K1 is compatible with a wide variety of cables and boom arms. The headset comes with a CABLE-II-X3K1 cable that helps to reduce structure-born noise.
