Superlux HMD685A Black PC headset

Broadcast Intercom Headset for Studio and Live Production

The Superlux HMD685A is a single-ear intercom headset designed for broadcast, theatre, and live-event production teams. The closed-back ear cup with a 40 mm neodymium driver delivers clear comms detail across a 20 Hz to 20 kHz range while keeping the wearer aware of the surrounding environment. A flexible anti-vibration gooseneck boom carries a dynamic cardioid microphone tailored for speech, holding its position without drifting.

What Makes This Headset Stand Out

The boom arm rotates fully for left or right ear wearing, essential for stage management, sound, and lighting roles where the headset may be worn for hours. Raising the boom to the upright position automatically mutes the microphone — a clean way to go off-mic without touching a button. The closed-back ear cup provides passive noise isolation without sealing the wearer off, so comms stay intelligible while the operator still hears the stage.

Technical Specifications

Every component is built around the realities of professional intercom use, from the high-impedance dynamic driver to the speech-tuned microphone capsule.

• Construction: Closed-back, single-sided — passive noise isolation with one open ear for situational awareness
• Driver: 40 mm neodymium — delivers clear comms detail across the full 20 Hz to 20 kHz range
• Headphone Impedance: 400 Ohm — pairs cleanly with professional intercom beltpacks and station gear
• Microphone: Dynamic, cardioid (unidirectional) — rejects ambient noise and focuses on the operator's voice
• Reversible Boom Arm — the gooseneck rotates fully for left or right ear wearing and holds its position without drifting
• Cable & Connector: 1.5 m cable with XLR4F (4-pin female) — plug-and-play with Tecpro, Clearcom, Granite, ASL, and Altair beltpacks

Who This Headset Is For

The Superlux HMD685A is the right choice for broadcast crews, theatre stage managers, live-event production teams, and houses of worship technical staff who need a reliable single-ear intercom headset for long shifts. It pairs directly with the Superlux IS103A intercom starter kit and works with the major wired intercom beltpack brands already installed in most venues. The reversible boom and automatic mute make it practical for shared use or extended wear.
