The Sennheiser HMDC 27 invites the Broadcast Commentators and Audio Engineers to experience the highest level of wearing comfort. As the top-of-the-line model of the HMS 27 Broadcast Headset Series, the HMDC 27 features NoiseGard™ active noise reduction which allows it to perform extremely well in very loud environments. By actively reducing the noise level by an additional 15 dB, this headset increases intelligibility while, at the same time, protecting the user's hearing and avoiding stress and fatigue due to noise. NoiseGard™ does not require the usual batteries but is conveniently powered via the microphone power supply from the broadcast desk or intercom system (Phantom powered P48).

The HMDC 27 is equipped with the automatically opening two-piece headband, hence, no pressure on the sensitive fontanelle. For those users who still prefer a conventional headband, a wide headband padding is included that converts the two-piece headband into a compact single piece.

Sennheiser HMDC 27 - Features:

  • Active noise compensation (NoiseGard™) additionally reduces noise by up to 15 dB. No batteries required: power supply via microphone bias voltage from the commentator's unit
  • Highest wearing comfort due to the lightweight circumaural and split-headband design (no pressure on the sensitive fontanelle)
  • Accurate and linear sound reproduction for very demanding monitoring
