WOW... I bought a pair this year (on ebay the power muffs for about $190) just so I could hear the birds better. I was not disappointed at all. I too suffer from tininitis and this has helped alot. I am looking forwart o using them during deer season too. I must say I haven't mastered all the settings yet. There is a volume knob and an inner wheel that adjusts the tones (or something like that) that you can hear. I just put batteries in it and all is great with the world. THe batteries in mine are a bit odd but Walmart (among other places) readily carries them. Even with the great hearing benefits it is equally as good to have them tone down the loud noises.

I am hoping they come out soon with a model to tune out the wifey... J/K
