"While I find I couldn't stand to keep these in my ears a whole night, I use these for the train, when I want to read or sleep but end up listening to someone else's tedious cell phone conversations. I can hear the train announcements, but people's voices are muffled to the point that I can't detect what they are saying, making them easier to tune out."
