The Sennheiser HMDC 27 is a top-tier professional broadcast headset engineered for commentators and audio engineers working in extremely noisy environments. Featuring a closed circumaural design, it delivers accurate, linear sound reproduction while ensuring maximum comfort through its lightweight build and innovative split headband that eliminates pressure points.

The HMDC 27 integrates NoiseGard™ active noise reduction, reducing ambient noise by up to 15 dB for enhanced intelligibility and reduced listener fatigue. Powered via phantom supply (P12–P48), NoiseGard™ requires no batteries, making it ideal for continuous operation.

A dynamic supercardioid microphone ensures crystal-clear voice transmission even under challenging conditions, while ActiveGard® technology protects hearing against sudden peaks above 110 dB SPL without compromising audio quality.

The headset offers modular flexibility with interchangeable cables and boom arms, a flip-away earcup for single-sided listening, and reversible microphone positioning. With a headphone frequency response of 4 Hz to 21,000 Hz, ultra-low distortion (<0.1% THD), and a maximum SPL of 125 dB (ActiveGard off), the HMDC 27 sets the standard for durability, safety, and premium audio performance in broadcast environments.
