Notch Hook Ups - Pre-Wired Bluetooth Hearing Protections

Upgrade your jobsite communication without compromising your hearing protection with Notch Hookups. These fully-certified earmuffs feature integrated high-fidelity speakers designed to connect seamlessly with the SENA 33i or W4 Comms systems. Engineering excellence ensures that the Hookups maintain their full NRR 25 certification even while the communication units are attached—eliminating the need to drill holes into your gear and sacrificing your decibel rating for connectivity.

Designed for the modern arborist, Notch Hookups are compatible with a wide range of industry-standard helmets, including KASK, Petzl, Studson, SOVOS, and Milwaukee. The ergonomic design focuses on all-day comfort, providing a secure seal that blocks out hazardous machinery noise while delivering crystal-clear audio from your crew. Whether you are performing technical removals or coordinating ground operations, these earmuffs provide the professional-grade protection and clear communication required for a safe jobsite.

Professional Connectivity: Notch Hookups are available as a standalone upgrade for professionals who already own a compatible communication device, or as part of a complete kit for those seeking a total communication solution.
