Elgin USA produces industrial hearing protection that is mainly passive and adds Bluetooth so users can hear audio while they work. Passive units block noise continuously and typically cut more sound than active designs.

The company also makes Rebel and Discord in-ear models, Fury Dual Defense over-ear muffs, and the Thumper, a 2.5-inch Bluetooth speaker that stands, magnets, or clips onto objects and uses an impact-resistant weatherproof case.

Rebel earbuds ship with foam, rubber, and standard tips. A double button press answers calls, other presses control playback, and a long press opens the phone assistant for volume changes.
