The most comfortable ear plugs I've worn!
I've been going to concerts regularly for around 15 years and in the past, I've either gone without ear protection (don't do that) or worn single-use foam ear plugs.  I knew I was going to be attending 4 or 5 concerts within the span of a couple of months, so I purchased a pair of Loop ear plugs and I'm happy to report they worked great!  They do a really excellent job of reducing the intensity of amplified sound in such a way that you can still hear it but it doesn't hurt or leave a ringing in your ears.  The foam ear tips fit really well and the loops stay in my ears even while bouncing around (the first time I wore them there was some slight discomfort but the next concert I could barely even feel that they were in).  My one complaint is that it almost completely shuts out non-amplified audio, so the crowds singing along at the concerts are barely audible, leaving me with the weird feeling like I'm the only one singing along... but it's so much better than disposable foam ear plugs, it's worth the slight drawback.  Bonus: the little carrying pouch is a nice feature, and I like that there are several color options so my wife and I could pick different ones and not get them mixed up.
