Notch Hook Ups

The Notch Hookups are fully-certified earmuffs with integrated speakers that seamlessly connect to the SENA 33i or W4 Comms systems. The earmuffs are comfortable for all-day wear and are compatible with popular arborist helmets like KASK, Petzl, Studson, SOVOS and Milwaukee. The NRR rating of 25 will protect your hearing on the jobsite, and the Hookups will maintain their NRR certification while connected to the SENA comms unit- no more sacrificing you dB rating by drilling holes. The Hookups are available as a kit for a full communication system solution or they are available on their own for professionals who already own a communication device but are looking to upgrade the earmuffs.
