Shure TH53 TwinPlex Subminiature Headset Microphone

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.

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.
