HMD 301 PRO Professional monitoring headset series

Single Side Headphone with Microphone  Closed headset for professional monitoring – specifically for broadcasters. The HMD 301 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   Headphone Acoustic principle dynamic, closed Ear coupling circumaural Frequency response 60 – 25,000 Hz Impedance 64 Ω Power rating 500 mW Sensitivity 108 ±3 dB SPL / 1 Vrms / 1 kHz Lmiter off Max.
