OK, after waiting until my Peltors crapped out, I ordered a set of Sordin Supreme Pro X from SRS Tactical. Hands down the best money spent on gear so far. 2 days to get them and love them. best hearing protection ever.
OK edited to add (above was made from my BlackBerry), I ordered the hearing Pro's on a Thursday and they showed up on Monday before I headed to the range, I was doing the happy dance at my post office box waiting for the delivery girl to show up (Canada post showed them as delivered on their tracking page). Once I got to the range I quickly removed them from the packaging (think Prom dress off of your date to get the sense of urgency I had), tossed the batteries in and away we went. Having been a Sordin fan for years I wasn't expecting to be blown away, but, I was. I wasn't so selfish to hog them all day though, I let everyone else there try them, including some gravel road cop instructors, who were all very impressed. Compared to Peltors, well really, there isn't any comparison. The sound quality, totally natural sounding, and no clipping, blows anything else out of the water. I also tested the MP3 plug and listened to some tunes while shooting on my own later on, probably the only place I could gather up a complaint. They limit the output to 82DB, now I'm not sure what volume I listen to my songs at normally, but it's a lot louder than that. Serviceable,ting but not these are hearing protectors, not headphones, so not a big deal. With the gel packs on them, I can wear my headphones, and still get a good seal around my ears, so if I really want to listen to music or instruction while shooting, I can (yes I listen to drills sometimes, I'm a shooting geek, what can I say).
if you buy these and don't like them, send them back, they give you a full refund. But you won't, trust me.
