it looks like the alveo vent helmet can take ear muffs , I have looked at the Petzel and similar style helmets , I may go that route when I need my next.
I like muffs because when we are felling like we were yesterday there is a lot of communications happening. about straps and chains as a tree comes down we pull it out in sections . on a felling day like yesterday I had 3 saws and I think I ran maybe a tank and a half with any saw I filled them up at the start in the morning and at lunch and we cut till 4 , end up spending more time positioning chain to drag logs out to where the skid loader can pick them up in 8 foot sections.
I was reading that the petzel and that style of helmet is taking over in construction also they realized the crush panels do more to protect the user from falling impact , it already has in other countries. the down side over the aluminum is that they have to be watched for UV weakening from being out in the sun
