What do you think about the comfort and quality of the products?
Earproof provides not only great music-plugs, but noise-cancelling sleep plugs as well. I've got them to replace the cheap (non durable) foamy yellow ones as one happy user. I have slept better, as these plugs help my ears to breath but still cancel out a lot of noises. It will hurt the inside of the ear a little in the beginning, as the material is a bit sturdier then the foamy old ones, but at least these stay in place. The little pain i felt was just my ears getting used to them and subsides quickly.
