3M Peltor is now shipping an improved TEP-200 tactical electronic earplug designed for the military, SWAT teams, and law enforcement. Level dependent technology instantly provides hearing protection for harmful noises and also increases low sounds during quiet periods.
The earpieces now have tiny antennas that allow audio to be received wirelessly using an optional neckloop. The TEP-LOOP-200 plugs into the 3.5mm jack on the remote speaker-microphone or any other audio source. The TEP-200 earplugs are receive-only. To transmit, the user would press the push-to-talk button and speak into the microphone. The TEP-200 is rated IP67 for submersibility and lasts up to 16 hours of continuous operation.
3M also introduced the LEP-200 designed for construction and industrial workers. Although it lacks the IP67 rugged rating, it offers the same functionality as the TEP-200. The original TEP-100 without wireless connectivity is also still available.
