Works good
I bought this for my home office as I talk on the phone for work a lot. I was hoping it would block out more noise than it does, but it works how it is supposed to. To block out extra noise, I may buy another. I do recommend for those of you who do not live in as noisy of an environment, and work from home. I do live in a prety noisy environment. I am not sure about using it to sleep, although I had it on for a little while to test it and felt very tired and had to go take a nap. My bedroom is quiet enough to sleep though and I prefer the noise of the TV anyway. I think this would work for people for sleep, you might have to get used to it though.
