Shure TH53 TwinPlex Omnidirectional Headset Microphone

The next stage in sound is the TH53 - a Shure TwinPlex™ Subminiature Omnidirectional Microphone with unbeatable clarity that can take a beating. Available in Black, Cocoa or Tan, the TH53 uses an innovative clutch system for quick adjustment in boom arm length and pitch — all with a simple turn of a knob. Plus, switchable sides with a durable 1.6 mm diameter cable and redundant ground compliment this professional headset that overachieves in reliability, audio quality, and comfort.

The TwinPlex dual-diaphragm technology yields extraordinary, off-axis response, and low self-noise while delivering life-like, exceptional clarity and robust low frequency response, free of digital interference. The cable itself is ultra quiet and has been tested to be the longest-lasting, most dependable cable in its class.

In dialogue or monologue. Song or speech. A single word can affect the whole story. Through sweat, noise, and wear and tear, your little lavalier has an enormous job to do. 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. So sound suits performer, not the other way around.

No more “sweat-outs.” 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 lavalier rises to the challenge, night after night.
