Nice. Which model do you use? And do they sell them in the U.S.? Not that I would mind making a trip overseas and getting away from the insanity here for a little while, but it adds to the cost.
I would assume that your local audiologist or music instrument store will know what the U.S. equivalent to these is. It seems to me that Elacin's biggest market is musicians who want a comfortable pair of earplugs with a flat frequency response.
