Query: Great product but not for the big guy.

My wife loves them, but they are really not usable in bed as the angle that you look through is not comfortable while lying down. Also, I tried them on and they are not for someone with a wider forehead. They do not comfortably fit around a bigger guy's head, but she loves them and wears them a lot around the house.Build quality is great and they do the job for her and since they were bought for her, they are fine.
