I was waiting to review these until I actually put them to the test at a concert. These arrived really quickly and are easy to insert even with my daith, tragus, and multiple cartilage piercings on each ear. The little carrying case for your key ring is super useful and kept me from losing them on my way to the concert. I was surprised at how much these really dampened the overwhelming LOUDNESS while still allowing me to listen to all the beautiful nuances in my favorite Tool songs. I was able to head-bang and even talk to people next to me with them in. I got out of the concert and took them out — and my ears aren’t ringing or hurting! This was well worth the money and I’m really glad I had them because I was able to enjoy the show more. Thanks!
