Sennheiser HMD 27

The Sennheiser HMD 27 is a professional broadcast headset for commentators and engineers especially for outside productions. HMD 27 are a closed and circumaural earcup design to provide a high passive attenuation but nevertheless unusually lightweight and comfortable over long working hours. Soft circumaural earpads endure a comfortable fit. The headset is similar to the HMS 26series 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.


  • Highest wearing comfort due to the lightweight circumaural design and the splitted headband (no pressure on the sensitive fontanelle)
  • Accurate and linear sound reproduction for very demanding monitoring
  • Dynamic Microphone, which stands out due toa strong and powerful sound pattern for an audio transmission in highest broadcast quality even in noisy environments
  • ActiveGard© (on/off switch) for protected hearing against noise peaks > 110dB
  • Modular concept of different cables and boom arms to offer highest flexibility
  • Cables of the cable 26-II series are compatible
  • Swiveling ear cap for single sided listening
  • Microphone can be worn either on right or left hand side
  • Wide headband padding is included that converts the two-piece headband into a compact single piece
