The reason I chose these was because you don't need spirit gum to keep them on; they just slip over your ears. They were a little tricky to put on but once you get them on, you can tilt them into the position you want and they stay on. They did not affect my hearing that much. After about 40 minutes they started to bother me but 20 minutes more and I forgot they were on. They're not super comfortable but they sure serve the purpose and I was the life of the party with them. They're actually pretty perfect.
