3M Model 20275005208- Peltor TEP-200 Black Tactical Earplugs. Practically new- used one time. My hope was they would block high-frequency noise, specifically the high-pitch noise of a dental drill. Come to find out, these aren’t great for low volume, high pitch noises. However they work quite well when it comes to loud noises like blowing off guns. Comes with various asserted 3M Peltor ear tips and wind screens.
