Built for demanding vocal applications in theater, broadcast, and corporate AV environments, this directional headset microphone pairs the 4088 CORE+ cardioid capsule with a dual-ear mounting system. The pressure gradient design maintains natural voice intelligibility across spoken word and sung passages without distortion, even at sustained high output levels. Its 116 dB dynamic range and extremely low self-noise floor make it equally effective for miked presenters in quiet studios and performers in high-energy stage productions.

The lightweight dual-ear hook design distributes contact pressure evenly while the flexible boom positions the 5.4 mm capsule precisely at the optimal near-field distance. IP58-rated protection against moisture and dust ensures consistent performance under stage lighting and outdoor conditions. The included connector interfaces directly with professional wireless transmitters, eliminating the need for external preamps or impedance matching in typical installs.

Designed for integrators managing multi-source reinforcement systems, the microphone's cardioid pattern provides substantial rejection of stage wash and monitor bleed. The flexible adapter system accommodates most wireless transmitter platforms without firmware updates or gain structure changes, simplifying inventory management across venues with mixed transmitter fleets.
