Product Overview
The Shure RPM53C/O-LEMO is a genuine OEM replacement boom arm for the TwinPlex TH53 subminiature headset microphone in cocoa finish, terminating in a LEMO3 connector. Designed for theater, broadcast, and live speech professionals who deploy the TH53 in cocoa on darker skin tones for improved concealment, this replacement part restores factory specification when a boom arm is damaged or worn. The LEMO3 connector maintains direct compatibility with wireless transmitters and preamps that use LEMO3 connections, making this a straightforward swap for an existing TH53C (cocoa) headset in active production inventory.
Product Description
The RPM53C/O-LEMO retains the TH53's clutch adjustment system for fast boom arm length and pitch repositioning, critical for rapid performer changeovers in live theater or broadcast. The cocoa finish is specifically designed to reduce visibility against darker complexions and hair, consistent with professional concealment practice in performance and broadcast environments. The LEMO3 connector is compatible with Shure wireless transmitters and preamps including the Shure RPM400LEMO TwinPlex Preamp. The 1.6 mm cable retains dual redundant ground construction for a secondary RF shield in wireless-dense live environments.

Frequently Asked Questions
Is this a genuine Shure replacement part?
Yes. The RPM53C/O-LEMO is an official Shure OEM replacement boom arm, manufactured to the same specification as the original TH53 component.
Which headset is this compatible with?
This boom arm is designed exclusively for the Shure TH53 TwinPlex subminiature headset microphone. It is not cross-compatible with other Shure headset models.
Why choose cocoa finish over black?
Cocoa finish is selected for use on performers with darker skin tones or darker hair, where the cocoa color reduces the microphone's on-camera and on-stage visibility more effectively than black.
What transmitters or preamps accept the LEMO3 connector?
The LEMO3 connector is used on select Shure wireless bodypack transmitters and with the RPM400LEMO wired preamp adapter. Confirm your transmitter's input connector before ordering.
