Good low profile ear protection - Walkers Low Profile Folding Ear Muffs

These work great for me. They are low profile. I have an "average" sized head, and they do fit snug and do provide good sound protection/attenuation, better than many others out there for the "low profile" category. A tight fit and good seal helps enable good sound protection. If your head is extra large or wider than most people, it might fit too tightly. I would recommend them for people with smaller sized heads or average sized heads.

Note that initially this product smelled chemically when packaging was opened, but the smell went away after it was aired out and put in the sun for a day.
