Pretty good
I gave these a go at a few death metal concerts so far. First off, I really appreciate the durable case with keyring these came in. Once you're in the middle of a crowd at one of these shows, things can get misplaced, but I was able to anchor this case down to the rest of my keychain.<br /><br />Comfort - I had no problem leaving these in for extended periods. Of course you can tell they're there, but I'd like to see a plug that you can't. These are quite a bit more comfortable than your basic foam plug though.<br /><br />Sound quality - I don't really buy into the notion that these are much better than regular ear plugs. I couldn't tell much of a difference, nor if any such difference was merely placebo.<br /><br />Ease of use - Much easier to put in than the foam ones you have to crush down to get into your ear.<br /><br />Value - Overall, especially considering the pretty decent price of these things plus the fact that they come with a good case and are of a durable material, I'd say these are a pretty smart investment. Maybe my ears are already too far gone from years of protectionless headbanging, but I couldn't hear too much of a difference over the cheap throwaway plugs. But I imagine I'll get enough use out of these to offset the cost eventually.
