The 4066 CORE Omnidirectional headset microphone with 3-pin LEMO connector for Sennheiser Wireless (small) from DPA Microphones offers clean and transparent sound quality with lots of headroom. The headset construction is unique with a detachable mic boom from the headset mount to switch and reattach to either the left or right side. Humidity, often an issue in theatrical applications, is not a problem due to the double-vent protection system and a drop stopper on the microphone boom. Also, the materials inside the mic are water resistant. These design elements make it very difficult for the microphone to fail due to humidity.
