SE-9 Headset

Sigtronics Wireless Headset System

Wireless mobility and hearing protection in one compact headset designed to be used with or without a helmet. Our SE-9 headset features our new heavy-duty flex boom and field replaceable M-83 noise-canceling microphone. The SE-9 is powered by standard size AA Nickel Metal Hydride (NiMH) rechargeable batteries.

System Operation: Adds a headset position to the existing intercom - does not disable any existing wired headset position. The wired headset PTT’s work as before. Pressing a wired PTT button sends out the corresponding wired headset mic audio to the radio and mutes all the other microphones. Pressing the SE-9 wireless PTT sends the wireless mic audio out to the radio and mutes all the other headset microphones on the intercom.

Easy Upgrade: The SE-9 wireless system does not require removal of the existing Sigtronics intercom installation. Each base unit and its wiring harness is made for a specific Sigtronics intercom model – US-45, US-67, US-12, or MRIM-2. This allows for easy installation, just plug the base unit in-line with the existing intercom wiring harness.

Small Size: You will only need a 5” x 3” x 2” space for the base unit. The charger is only 2” long and can be placed near the SE-9 headset.
