Clear-Com CZ-WH340 Wireless All-In-One Headset 2.4GHz

The Clear-Com CZ-WH340 is a single-ear, all-in-one wireless headset built for professional intercom applications in live production, broadcast, and theatrical environments. Operating in the license-free 2.4GHz band with frequency-hopping spread spectrum technology, it pairs exclusively with the BS340 base station and is compatible with the DX340ES digital wireless system, supporting up to four full-duplex or fifteen half-duplex headsets per base station. This makes it a scalable solution for production teams that need reliable, simultaneous crew communication without the cost or complexity of licensed spectrum.

For engineers and production coordinators who depend on clear, uninterrupted comms during live events, the CZ-WH340 delivers 7kHz wideband audio with 64-bit encryption and less than 2% system distortion. The TDMA-based architecture and dual-diversity internal antennas contribute to consistent RF performance across dynamic venue environments. Continuous latched mode supports hands-free operation throughout a show, while push-to-talk mode extends battery life significantly beyond standard shift lengths. Compared to analog wireless intercom headsets in the same class, the CZ-WH340 benefits from digital wideband clarity and encryption without requiring FCC licensing or frequency coordination.

The lightweight single-ear form factor minimizes fatigue during extended use, making it practical for stage managers, camera operators, and crew members who wear the headset for an entire production day. The included BAT50 battery and LED status indicators with voice prompts keep users informed of power levels without interrupting workflow.
