Shure TH53 TwinPlex Subminiature Headset Microphone

Shure TwinPlex stands up to the toughest conditions to make every word a clear statement of quality. Natural audio at high or low frequency, the innovative dual-diaphragm captures the complete weight of your voice. And the capsule design maximizes effective surface area in an easy-to-conceal package.

The superhydrophobic coating keeps perspiration from upstaging the sound. And the medical-grade cable technology flexes to fit the costume design and the demanding schedule. So your headset rises to the challenge, night after night.

The TwinPlex™ TH53 offers the natural sound quality of the new TwinPlex element combined with the ease of a light and fully adjustable headset frame. With an innovative clutch system, the TH53 headset allows for quick adjustment in boom arm length and pitch-all with a simple turn of a knob. Plus, switchable sides and a durable 1.6 mm cable with redundant ground round out this professional headset that outperforms the competition in reliability, audio quality, and comfort.
