The new HMD 300 PRO broadcast headset delivers great sound with exceptional fit and comfort for long production days. The new series is available in single (HMD301pro) and dual sided (HMD300pro) models and features a soft, notched headband that reduces wearing pressure on top of the head, as well as newly designed earpads with a comfort zone that reduces pressure for users who wear glasses.


The HMD 300 PRO headsets are also equipped with selectable (on/off) ActiveGard™ limiter that protects users from excessive sound pressure levels greater than 110dB, as well as our popular modular cable system, to quickly interface with a wide range of professional broadcast equipment. With the HMD 300 PRO, the dynamic, hyper-cardioid boom mic has been combined with a new headphone design that delivers detailed, linear sound and an excellent seal for high passive noise attenuation.

The HMD 300 PRO also offers you the option of customized design: you can for example have your logo applied to the side – making it clearly visible.

Features:

  • ActiveGard (on/off switch) for protected hearing against noise peaks > 110dB
  • Highest resolution due to accurate, linear sound reproduction, optimised for speech intelligibility
  • Dynamic, noise-compensated supercardiod microphone for clear communication even in noisy environment
  • Microphone can be worn either on right or left hand side
  • Comfortable padding design allows for extended use in long wearing sessions
  • Superior ambient noise attenuation in loud environments due to closed passive earcup construction
  • Due to our established modular concept the cables of the cable 26-II series are compatible
  • Foldable earcup design for space saving storage
