Only ones I've used, but GREAT
Surprisingly easy to hear conversations with the person next to you at loud concerts. I'm a professional musician and semi-professional recording engineer and find these great for saving your ears at concerts. I actually enjoy listening to concerts MORE with these than without them, plus no ringing at the end of the night. As a vocalist, however, I prefer not to use them on stage because I feel like I can't hear myself as well even though I can hear other things well.
