Standard Horizon CMP460 Submersible Noise-Cancelling Speaker Microphone

The Standard Horizon CMP460 Submersible Noise-Cancelling Speaker Microphone is a rugged, IP57-rated communication accessory built for law enforcement, military personnel, and field operators who demand reliable hands-free audio in harsh environments. Whether conducting tactical operations in wet conditions, managing high-noise environments, or maintaining secure communications during extended deployments, this push-to-talk unit delivers professional-grade audio clarity when mission-critical performance is non-negotiable. Its compact 4 x 3 x 8 inch form factor and lightweight 0.4 lbs construction make it ideal for belt mounting or integration into existing two-way radio systems without adding significant burden to tactical loadout.

The CMP460 features active noise-cancelling technology that filters out ambient background noise—critical during high-decibel operations like breaches, vehicle operations, or industrial environments where clarity deteriorates rapidly. Its IP57 dust and water protection rating certifies submersion capability to 3 feet for up to 30 minutes, ensuring survivability in river crossings, boat operations, or sudden immersion scenarios common in specialized tactical units. The integrated push-to-talk switch, speaker, and microphone eliminate the need for multiple components, while Intrinsically-Safe certification (when matched with appropriate radio equipment) supports use in hazardous atmospheres where explosive gases or vapors may be present, such as certain industrial rescue or HAZMAT response scenarios.

The CMP460 is purpose-built for users operating Standard Horizon-compatible two-way radio platforms and integrates seamlessly with tactical communication systems deployed across law enforcement SWAT teams, military small units, and emergency response organizations. Its submersible design makes it particularly valuable for dive teams, water rescue units, and amphibious operations where traditional speaker microphones fail. Operators in noise-intensive environments—aircraft flight decks, shooting ranges, industrial facilities—benefit measurably from the active noise cancellation, which preserves voice intelligibility and reduces communication fatigue during extended operations.
