Best combination of comfort, ease of insertion, noise reduction, and price
My wife bought these for me as a gift after reading about them in a holiday gift guide. I wear these to exercise classes at the gym, to weddings and parties where the DJ likes it louder than I can tolerate, and under my over-ear protection for indoor shooting.  I have tried many earplugs and strongly recommend these as the best combination of comfort, ease of insertion into the ear canal, noise reduction, and price.  The best bang of the buck is the free foam rollers you get on the airplanes, but if you want something that looks more subtle in your ear, and which you don't have to roll in the grime of your fingers, this is the best choice I have come across.  NOTE: I have never worn these for prolonged periods of >2hrs, and I have not worn them to live music.
