This flexible miniature microphone is the chosen headband for theaters on Broadway and West End. It adjusts easily to allow mounting on either right or left. The miniature microphone boom may also be used alone in applications where the headband is not needed.

It is designed with attention to the humidity problems that can occur in theatrical applications. A double vent protection system, a drop stopper on the microphone boom, and water-resistant materials inside the microphone help microphone failure due to humidity. The headband surface is matgold plated and headband earhooks are covered with a silicon hose.

The 4066 offers clean and transparent sound quality with lots of headroom. Its 6 mV/Pa sensitivity matches the level of the human voice to the general input sensitivity of most wireless transmitters. If powered correctly, the microphone will handle sound pressure levels up to 144 dB SPL before clipping occurs.

A wide range of connection adapters makes the the 4066 compatible with most professional wireless systems, plus 48V phantom XLR connection.
