This is another reason I think its refurbished. I always replace my Birkenstock with another pair of Birkenstock because when a shoes as comfortable as these you dont want to replace them with anything else. Not recommended I went with the 9-10 and they fit great. Of the 4 replacement earpads that I bought, these are the best. The high frequencies are not harsh or tinny, and the low-end will never be muddy or buzzy. It did not block the wind because it was mounted behind the SUV so the vehicle went smoothly on highways. For what you pay, theyre really good chat headphones. We have purchased 2 pairs of these, a blue pair and a pink pair for my son and daughter. 5 fit perfect.
