My Peltor electronic muffs have just about had it, and they aren't likely to be cost effectively repaired.

I've heard some good things about the Swedish made product marketed under the trade name of Sordin. Apparently some branches of your military use it. It's quite pricey, so I'm wondering if it is worth the extra money. Also, if it is worth the extra bucks, where is the best place to get it. (Don't say "enlist", because I'm too old.) :)
