Title: Not good for sleep: they hurt
Review: I bought a pair of this ear plugs from Amazon. I didn't use them for swimming, but for sleep. After wear them for 10 to 20 minutes I have to take them off because they hurt in my ear channels. I tried them a lot of times, with the same result: I couldn't sleep with them in my ears. They seem very well designed, but maybe they must be used for what they were made for: swimming.
