Professional presentation headset

The Galaxy Audio ESM4 is a single-ear omnidirectional headset microphone designed for presenters and performers who need clear voice capture without blocking both ears. Its beige finish suits stage and broadcast environments where a low-profile appearance matters. The flexible boom allows precise positioning for consistent audio pickup during speeches or performances.

Lightweight comfort and connectivity

Weighing only 0.28 oz, the headset remains comfortable through long sessions without excessive clamping force. A four-foot detachable cable and included windscreen protect against handling noise and wear. Four Sennheiser connector cables provide compatibility with wireless transmitters from Shure, AKG, Audio Technica and Galaxy Audio body packs.

Omnidirectional capture under load

The back electret condenser element covers 85Hz to 15kHz, capturing the full speaking range with equal sensitivity from all directions. This pattern maintains consistent levels when the speaker turns their head, avoiding the drop-off common with directional capsules. The design minimises background intrusion while preserving natural vocal tone during extended use.

Questions about this item

How do I connect the ESM4 to my wireless transmitter, and which step do people often miss?

Plug the detachable 4 ft cable into the headset, then choose the one Sennheiser connector that matches your transmitter — Shure, AKG, Audio Technica or Galaxy Audio — and snap it onto the body pack; the mistake is leaving the other three cables attached instead of storing them.

What part will need replacing first after months of daily use?

The foam windscreen will degrade from moisture and handling long before the electret capsule or cable, so keep a spare pack handy for quick swaps.

At what frequency does the omnidirectional pattern start to narrow under sustained high-SPL use?

The capsule maintains its stated 85 Hz to 15 kHz response; pattern narrowing is not a specified limit, so the first practical ceiling is the 15 kHz high-frequency roll-off.
