Obviously, if you don't have the original Earplugs, buying this wouldn't allow you to get all the
mileage you could out of these if you had the original DVD.
Regardless, if you do, you know
how high quality these "earplugs" are. They function the same as spongeballs except really give a
MEANING to what you are doing.
I very much enjoy these. PLEASE don't buy these unless you
have the original (with the DVD) first though. Find out all the tips that Jay (the creator) gives
and really get all you can out of these.
