These plugs stay in your ears!
I’ve used these primarily for riding my motorcycle and they are fantastic!  I also use them during the day on occasion when I’m trying to sleep since I work night shift.  I haven’t been to a concert yet since my purchase of these but I will definitely be using them for concerts in the future.  I love them because they stay in place much better than the 99 cent foam ear plugs.  Well worth the money spent!
