Sennheiser HMD 300 PRO Broadcast Headset without Cable, Dual Sided (Used)

Like New: Open box product with no signs of use.

Closed headset for professional monitoring – specifically for broadcasters. The HMD 300 PRO Series takes the strain off the user thanks to minimal, optimally distributed pressure, particularly soft viscoelastic earpads and a fontanelle recess in the headband.

All acoustic elements are designed for maximum intelligibility; highly-sensitive transducers generate a clear, distortion-free sound and a dynamic microphone reproduces speech with a particularly high level of detail.

Key Features

• Maximum wearing comfort even during extended sessions
• High-resolution and distortion-free monitoring sound
• Outstanding speech intelligibility thanks to a supercardioid, dynamic microphone
• Switchable Peak Level Protection protects against volumes over 110 dB(A)
• Efficient filtering of ambient noise and structure borne noise
• Customized design of earpads possible
