Comfortable and unobtrusive to wear, these in-ear hearing protectors are less bulky than earmuff-style protectors, so they won’t get in the way of a hard hat or other headwear. They have a high Noise Reduction Ratio (NRR 27) and are compatible with Bluetooth 5.0, maintaining up to two active connections -- to monitor a phone and a communications radio at the same time, for example.
The noise-cancelling microphone lets you communicate over either channel without having to remove yourself from a noisy environment, and the rechargeable battery (USB cable included) provides 16 hours of talk time. They have an IP67 rating, so they cannot be infiltrated by dust, perspiration or water (to a depth of 1.5m/4.9').
Built for hard use, each earbud has a sturdy ear stem made of chrome-plated brass and a length of pliable wire that can be formed to a snug fit behind your ear, holding the earbud in place as you move about. The controller has a slim design with large rubberized buttons for easy operation.
They come with one pair each of small, medium and large foam earbud tips (medium fits most; replacements sold separately) as well as a pair of conical earbud tips for listening to audio without added hearing protection, and a soft-shell pocket case with room to keep all components together in one place. ANSI-certified, OSHA-compliant.
