The 3M PELTOR H505B is a passive, behind-the-head welding earmuff rated NRR 22 (ANSI S3.19). The neckband sits behind your head instead of over the crown, so it clears the shell of a welding helmet, a flip-up face shield, or the brim of a hard hat — the exact spots where a standard over-the-head band fights for room. If you weld, grind, or work under headgear and a top band keeps knocking loose, this is the form factor built for the job.

Where It Earns Its Slot

Honest Limits

Honest limits start with fit: no hearing protector delivers its label without a verified seal, and this one is no exception. Plan the NRR 22 label at roughly 7.5 dB of field reduction under OSHA's subtract-7-and-halve estimate, and let your measured exposure — not the box — decide whether it is enough. It protects against noise only — impact, chemical, and other hazards need their own equipment.

Why trust WC Safety

WC Safety is an independent, affiliate-supported review site. It is not a retailer: it holds no inventory, takes no orders, and earns only from qualifying purchases through clearly marked links — which never changes what a product is rated to do. Standards language is taken from the regulation text directly, and ratings are reported as the manufacturer publishes them. We run no laboratory and perform no testing of our own. Where published sources disagree, we say so and plan on the conservative figure rather than the flattering one.

Our methodology

Figures come from the regulation and the published specification, in that order. Derated numbers are calculated, not estimated. Nothing here is presented as a measured result, because we measure nothing.
