Sennheiser HMDC 27 Dual-Ear Over-Ear Broadcast Headset with Dynamic Mic and Active Noise Reduction (No Cable)

Sennheiser HMDC 27 Dual-Ear Broadcast Headset for Loud Production Environments

The Sennheiser HMDC 27 Dual-Ear Over-Ear Broadcast Headset with Dynamic Microphone and Active Noise Reduction is the perfect solution for professionals working in high-noise environments like live TV and radio production. Whether you're in a control room, an outdoor event, or a live broadcast studio, this headset delivers clear, protected communication when it matters most.

Advanced Noise Cancellation with NoiseGard Technology

What sets the HMDC 27 apart is its integrated NoiseGard active noise reduction, which reduces ambient noise by up to 15 dB. This dramatically improves speech clarity and helps protect your hearing from prolonged exposure to loud environments. Unlike many other headsets, NoiseGard is powered by phantom power (P12 to P48), so there’s no need for batteries, keeping your setup efficient and lightweight.

Comfort-First Design for Long Production Days

Built for comfort, the lightweight frame features extrasoft ear cushions and adjustable headband padding that prevent pressure on sensitive areas of the head. The headset comes with a unique two-piece headband that automatically adjusts for a secure fit without applying pressure to the fontanelle. If preferred, you can convert it into a more traditional single-piece design using the included wide headband pad.

Broadcast-Quality Audio with Hypercardioid Microphone

The HMDC 27 includes a dynamic hypercardioid boom microphone that delivers reliable broadcast sound quality with a frequency response reaching up to 18 kHz. Designed for clear, directional voice pickup, it ensures your voice comes through cleanly even in noisy surroundings. The microphone boom can be positioned on either the right or left side for user flexibility.

Hearing Protection and Professional Isolation

The closed-back, over-ear earcups offer excellent passive noise isolation. Combined with ActiveGard limiting technology, which includes three selectable attenuation levels (Off, 95 dB, and 110 dB), the HMDC 27 provides essential hearing protection without compromising sound quality. This makes it ideal for high-decibel environments where communication clarity and ear safety are crucial.

Modular and Flexible for Professional Workflows

Designed with a modular system, the headset is compatible with a range of optional cables and boom arms, allowing for customization based on your broadcast setup. Please note, a cable is required for operation and is not included with the headset. The swiveling earcup also allows for convenient single-sided listening when multitasking during live productions.
