Stopped-Ear Barbute

Close barbute with the ear holes filled by poured lead plugs and a felt lining stitched over them from the inside.

Nothing the wearer hears can command, frighten, charm, or deafen them; any Mind save the wearer would make against a voice, a sound, or a spoken spell succeeds automatically, and no spell that works by voice reaches them at all. The wearer also cannot hear speech, orders, or warnings from their own side. No other helm, circlet, or head-ward functions while it is laced on.
