Love these ear plugs!
These are the best, most comfortable ear plugs I've ever used.  It's so nice they are reusable.  After a few uses, I clean them off with an alcohol wipe & they are as good as new.  They are great for sleeping, working, and cancel out noise better than any ear plug I have previously used on an airplane.  Because they are so easy to just pop in your ear, I have even been able to have my daughter use them on flights so that she can sleep.  I highly recommend these earplugs!!
