Electro-Voice HR-1 A4F Single-Side Headset with A4F Connector

Built for dependable voice communications in security, surveillance and monitoring operations, the Electro-Voice HR-1 A4F single-side headset provides clear, focused audio where it matters most. This professional headset combines a flexible dynamic noise-canceling boom mic with a 21dB passive noise reduction rating to suppress ambient sound and keep messages intelligible in moderately noisy control rooms, patrol vehicles, and monitoring stations. The HR-1's audio response (100 Hz–3 kHz) is tuned for speech clarity, while the 5' cable and A4F (XLR-style) interface ensure compatibility with industry-standard comms and intercom gear. Comfort is engineered into every shift: a moleskin-covered headband and evenly distributed ear cushion pressure eliminate hotspots during extended wear, and the single-sided design keeps one ear free for situational awareness. Lightweight yet rugged, the headset folds flat for transport and secure storage between deployments. Ideal for security teams, surveillance operators, dispatch centers and IT-managed monitoring installations, the Electro-Voice HR-1 delivers professional-grade performance and comfort. Add the HR-1 A4F to your kit for clearer, more reliable communications on every shift.
