content: The good reviews outnumbered the bad so I went ahead and purchased. Sadly, that was a mistake. These arrived today, and as another reviewer said there are three sets in the package and the "case" is a single small black cloth bag. OK. I could live with that. What I can't live with is the poor job they do! Almost like having nothing, I swear. Seems odd they're rated to 26 dB. I'd certainly not want to trust them to protect my hearing (not just for comfort) on a firing range, as the description suggests. Yes, I'm sensitive to noise, which is why I use ear plugs. These didn't even damp the light blower noise from a small personal fan, much less the other environmental sounds in my workspace. I was looking forward to not having to mash and insert the foam plugs but I'll definitely be going back to those...they WORK!
