Just thought I'd do a bit of a review on my 3M Peltor Tactical Sport.
So far they are great. I've only used them sighting in and load testing haven't used them in the field yet.
The amplification is great you can turn up to LOUD or dim until almost inaudible and you can clearly tell the direction a sound is coming from rather than just hear the sound which would be great hunting.
It also doesn't cut out when loud sounds happen it just compresses the sound to a bearable level so if you're at the range and yacking to the bloke next to you and someone 2 bays down fires a shot you don't have the issue of the conversation cutting in and out everytime someone fires a shot. Don't know how durable they'll be but so far they seem good!
They were about $200 on eBay. Dunno if I was ripped or not but they work good so I'm happy I'll give em 9/10
