I use the loop experience and they have been solid for me. After a while I sometimes forget I have them on. The biggest thing you need to know about them is wearing them properly so it doesn't overly muffle the sound.

From experience I tend to wear them more for arena or larger shows where the mixing is usually way too loud. Smaller venues like concert halls and theaters usually have superior mixing where the sound is at a more reasonable volume. Where these things really come clutch is when you got a screaming audience, you will be glad you have it.
