The RAT phones arrived a couple of days ago. First impressions.......They are top of the line MSA (Mine Saftey Appliance) ear muffs. They have been customized to make them metal detecting headphones. http://www.msanorthamerica.com/catalog/product503251.html Can't find a price on the muffs alone. However they must put some absolutely superb speakers in them. The cloth interior of the earpieces themselves is a nice touch. They block out 99.9% of all ambient noise. To do this they have to fit tight. They are tight fitting muffs for sure but the cups are so large they are comfortable as all get out. Now I've worn earmuffs in chemical plants many many many thousands of hours over the last 31 or so years. These really do feel nice. The forward lope I'll call it of the headband makes for that "it doesn't feel like they are about to fall off" feeling like a lot of muffs do. I used them in the yard for a couple or three hours the last two afternoons. Now I have to run my volume on the X 705 a good bit higher, was 16, now 21, to be able to hear with my hearing loss. See "31 or so years" above. The tones are clear as a bell and I can run the threshold at a very clear barely audible mode. It is amazing the very faint tones I've been making/testing with coins in the yard with. I'll give them an "A" right at the moment. I need to get in several half day hunts to know more. One concern I have is that virtually all the MSA muffs I've used over the last 31 years have had earpad failures or cracks in them after a couple of years use. The instructions do tell you to wipe the muffs with a damp cloth to wipe off any accumilated sweat present with each use. I'm guessing the salt in the sweat makes the cushion cover crack, that would be my personal experiences with them. More later as I use them..............
