Shure RPM53C/O-NC – Replacement Boom Arm for TH53, Cocoa, Bare Wire
Product Overview
The Shure RPM53C/O-NC is a genuine OEM replacement boom arm for the TwinPlex TH53 subminiature headset microphone in cocoa finish with a bare-wire (no connector) cable termination. Designed for systems integrators and technicians who require field-termination flexibility to match a specific transmitter interface, this replacement part restores factory specification to a damaged TH53C (cocoa) headset while allowing the installer to add the appropriate connector on-site. It is preferred when the required connector type is not available in a factory-terminated variant, or when custom cable routing is part of the installation design.
Product Description
The RPM53C/O-NC retains the TH53's clutch adjustment system for fast boom arm repositioning during performer changeovers. The cocoa finish reduces on-camera and on-stage visibility against darker complexions and hair. The bare-wire cable end provides maximum flexibility for systems integrators who need to route cable through costume or staging infrastructure before terminating to a specific connector. The 1.6 mm cable maintains dual redundant ground construction for additional RF shielding in wireless-dense environments. For factory-terminated cocoa variants, see the RPM53C/O-LEMO or RPM53C/O-MTQG.

Frequently Asked Questions
Why choose a bare-wire termination?
The NC variant is preferred when your transmitter uses a connector not available in a factory-terminated variant, or when an integrator or technician needs to custom-terminate the cable during installation.
Is this a genuine Shure replacement part?
Yes. The RPM53C/O-NC 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.
Why choose cocoa finish?
Cocoa finish is selected for performers with darker skin tones or hair to reduce on-camera and on-stage microphone visibility.
