PRODUCT SPECIFICATION
HMD 300 PRO | HMD 301 PRO | HMD 300-XQ-2
Professional monitoring headset series
1/1
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.
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
