3M Earmuffs, Black/Red, Cap Mount

My PPG helmet originally came with the Optime 101, but they didn’t knock out enough of the engine noise. SO, I upgraded to these 105’s. They are much quieter without being too much bigger. It was a little harder to get my Sena 10R installed since there are two layers of plastic in the muffs, but it works great now. I felt like this was a great value for the money. I’d purchase these for flying or for any other helmet-mounted noise protection.
