I bought these based off of some reviews I read and I have to say I am dissapointed. I'm a very light sleeper and was hoping that it could help drown some of light noises my neighbor produces late at night. Boy, was I wrong. It did absolutely nothing! I could hear so clearly that it was almost like I had nothing at all in my ears. Plus, they don't fit well at all, so when you try to fit them in your ear, they fit for a second and then stretch back to its regular size. Don't bother.
