STUDSON Universal Ear Defender – ED-3B

Designed for high-noise environments, the STUDSON Universal Ear Defender (ED-3B) delivers reliable, helmet-mounted hearing protection without compromising comfort or mobility. Built to integrate directly with most industrial safety helmets, this system eliminates the need for a separate headband—keeping your gear streamlined and jobsite-ready.

With a Noise Reduction Rating (NRR) of 26 dB, these passive ear defenders help reduce exposure to harmful noise levels while maintaining situational awareness. The three-position arm system allows you to quickly switch between active protection, standby, and parked positions—all without removing your helmet. Lightweight, durable, and dielectric, the ED-3B is built for all-day performance in demanding environments.
