Thanks, but I'm going with the over ear protection, so I have a fat heavily insulated set of ear muffs that I will no doubt hate in the heat, but man are they quiet.
Now I just want eyewear that won't defeat their purpose.
Interestingly, most of the silicone or other foam ear inserts I looked at weren't anywhere close in noise reduction capabilities (according to the NRR or whatever it was rating) compared to the top shelf ear muffs. Taking it all with a grain of salt, since many vendors over-claim or use non-standards-based rating systems if they can get away with it.
I've used silicon ear inserts a lot in the past for other things, but was shooting for max coverage this time because this mower was really getting to me with the noise.
I'm curious what you have for ear muffs, as most of what I've found have less noise reduction than ear plugs. When running chainsaw for any length of time I use both plugs and muffs, otherwise I will hear the darned thing echoing in my head all night.
You say that you will hate them in the heat and I agree. Yet you also would hate asking "what?" every time somebody speaks to you... and don't ask me how I know that.
