Setcom Half Shell Helmet Kit

Half Shell Helmet Kit – MOCS II / 63 Series / 31 Series

The Half Shell Helmet Kit is a purpose-built internal communications solution designed for use with half-shell motorcycle helmets in public safety and motor unit applications. Designed to work with Setcom’s MOCS II, 63 Series, and 31 Series communication systems, this kit provides dependable audio performance while preserving helmet balance, comfort, and overall rider safety.

Two configurations are available to support different microphone and wiring options while maintaining the same physical mounting and helmet fit.

Operational Overview

This internal-mount helmet kit installs inside the helmet shell, allowing riders and officers to communicate clearly and effectively while maintaining head protection. The low-profile speakers and microphone are engineered to provide clear audio without interfering with helmet comfort or safety performance. Both configurations use the same mounting method and helmet compatibility but are tailored for different communication system setups.

Construction

The Half Shell Helmet Kit uses rugged components designed to withstand vibration, wind noise, and the demands of public safety operations. Speakers are shaped to fit inside helmet ear recesses, and cable routing is cleanly managed to preserve helmet structure. The kit’s components are built for durability during extended use in various riding and emergency response scenarios.
