Sennheiser HMD 300 S Single-Ear Over-Ear Broadcast Headset

Broadcast Communication Headset Built for Backstage and Control Rooms The Sennheiser HMD 300 S is a closed-back, single-ear, over-ear headset designed for high-noise environments such as backstage coordination, live event production, and intercom communication. It provides professional-level speech clarity with reliable noise isolation and hearing protection. Featuring a dynamic supercardioid boom mic and ergonomic design, it’s tailored for production crews who require consistent communication and comfort during long shifts. Closed-Back Over-Ear Design for Focused Monitoring This headset uses a closed-back, over-ear configuration to minimize external noise and help the user focus on incoming communication. The single-ear design allows you to stay connected with your environment while maintaining clear intercom monitoring. Ideal for technical staff and stage managers working in bustling venues, this design supports real-time multitasking with reliable audio isolation. ActiveGard Technology Protects Hearing from Loud Peaks Sennheiser’s integrated ActiveGard hearing protection helps guard against sudden spikes in audio. With selectable settings (off, 95 dB, or 110 dB), users can adapt to their specific audio environment without risking hearing fatigue or damage. This feature is especially useful in unpredictable live production scenarios where audio peaks may occur without warning. Dynamic Supercardioid Microphone Enhances Voice Intelligibility Equipped with a dynamic boom mic using a supercardioid pattern, the HMD 300 S delivers speech clarity while rejecting ambient noise. Operating up to 18 kHz, it ensures detailed and focused vocal capture—ideal for backstage or broadcast communication where background noise must be controlled. The microphone can be positioned on either side of the headset for ergonomic flexibility. Comfortable Wear for Extended Use During Long Events The headset is built with comfort in mind, featuring lightweight construction, a padded headband, and soft ear cushioning. This makes it well-suited for long days of rehearsals, live shows, or production work. The earcup also folds flat, offering a compact profile for storage and transport when the day is done. Modular Design Supports Flexible Cable and Mic Options The HMD 300 S is part of Sennheiser’s modular system, allowing compatibility with a wide range of cables and boom arms. This flexibility lets users adapt the headset to different systems and signal flows. The headset is shipped without a cable, giving you the freedom to choose the connection type that fits your setup best. Reliable and Durable for Demanding Communication Workflows Whether used in a theater control booth, live stage production, or remote broadcast setup, the HMD 300 S is built to last. Its robust build quality and professional-grade components ensure stable performance under regular use. It’s a dependable choice for communications teams who can’t afford technical hiccups.
