The 3M Peltor tactical earplugs help protect hearing while enhancing situational awareness and communication in demanding operational environments. Thanks to their level-dependent function, the TEP-200 EU and LEP-100 EU earplugs provide insulation when noise levels rise. At the same time, they ensure that soft sounds in quiet environments are not missed. The earplugs also include a small antenna, allowing audio signals to be wirelessly received via an optional neckband. The 3M Peltor neckband can be used with audio sources that have a 3.5 mm output. When connected to your radio or shoulder microphone, audio signals can then be transmitted wirelessly.
