Comfy and my ears weren't ringing...
I've only really used it once (you know, winter hibernation does not exacerbate crazy partying, at least for me), but they worked pretty well. I did not have the ringing in my ears that I usually get after a hard night of loud music, which is a huge plus. I also was able to hear the music pretty well, but unlike other reviews that said that it was conducive to hearing other people, I can't really promote that piece. Everything seemed muted and if people yelled in my ears I could then hear them, but when it comes down to  the bottom line, when you don't have these ear plugs, people would have to yell in your ears to hear them anyway. This way, I'm doing the same thing, except for the losing my hearing part of that narrative. It felt like I was in my own bubble, just like if I was sticking my fingers in my ears to block out the sound and everything sounded a little nebulous. And that's the reason why it wasn't a full 5 stars; I love the convenient little container that these little earplugs are housed in which upped the ante and the HUGE important piece is that it makes me feel like I am saving my hearing! I would definitely recommend it for people, especially for the price that I paid, long term...REUSABLE is a key word for price. Enjoy!
