Earplugs for conerts?

What?

Yeah Matt8268, I concure as well. The old "tear off a piece of napkin" thing has been saving my ears for years as well!
THE ABSOLUTE BEST ADVICE I EVER GOT WAS FROM BOTH MY DAD AND A FELLOW AUDIO ASSOCIATE, IN REGARDS TO PROTECTING MY HEARING!
I look back at all the years of going to the drag races and such, and all the times my friends wanted to play their music WAY TOO LOUD, and I thank God I had people there to warn me ahead of time! In such cases, I always plug my ears up with something, or ask people to "turn it down!". I certainly know of many many people around me who don't even consider it, or presure others into thinking that "if it ain't loud, your too old"...and other FOOLISH PIER PRESSURE!
I'VE ALWAYS BEEN MAN ENOUGH TO NOT FOLD TO THE PRESSURES OF OTHERS HERE(again, thanks to good parenting and relationships I guess)Also, I think having some grandparents and relatives that have virtually lost most all of their hearing from factory work and heavy loud machinary over the years, I also learned from their mistakes and ignorance!
I like to think my hearing is excellent and very accute! So my best advice EVER TO ANYONE ABOUT AUDIO AND YOUR EARS, is "PROTECT YOUR EARS/HEARING!!!!"..YOU ONLY HAVE ONE SET!

In a similar setting, I was absolutley shocked to see how many people were NOT wearing hearing protection at the US Grand Prix when I attended it in Indianapolis. These F1 cars are LOUD, and with stands on both side of the front stretch, the sound does not escape easily!

I've used the Eytomic ear plugs for the past several years, even when mowing the lawn, etc. They offer the most linear attenuation that I've found so far. Highly recommended.

I know what you are talking about JCdem and the plugs you are asking about are a lot different than the suggestions put forth above. The ones i've heard about range from ones that are custom fit to your ears to ones that are generic fit for a lot less money. I've considered them for use when playing live. Tried the other routes and too much gets lost so the feel of the music coming out of my amp isn't the same. An ear doc may be able to direct you. Guitar player or another similar musician mag may also help. that said, i've found that the acoustics at big halls are so bad that even the cheapie plugs clean up the sound so i can hear what's going on better rather than a big cluttered noise assault.
