Hadn't had any problems except dead batteries in the Peltor TAC 6s which I have had for several years. The ear cups are reversible on the yoke to place the cutout or scallop in the cup downward where interference with the comb might take place but I don't recall hitting them with the comb. If you have low-mounted ears, I suppose you would. The white noise from steady wind takes some getting used to. I'm still laughing at the picture of Shotgun with his C-clamp. What I like best about the Peltor muffs is that they are so much better than the Remington model I had previously in terms of sound transmission (words such as pull, mark, harrr, aaayah, and now have a lot of importance in a certain context). I'd like to have that ear-channel chingus but will have to wait til I have the golf cart and my own five-acre sporting setup--in other words, forever.
The Peltor is often found deeply discounted.
