The woman kept saying it was because of the soles, and that this is why these are less expensive. I bought 6 total. Andiamo per gradi. Also, I checked the UGG website to confirm that Orva Stores was an authorized retailer. The only reason I did not send them back is because someone threw the packaging away, before I got to test them out. It cancels various noises from an airplane, an AC fan, falling water from a tab, a car passing by me, etc. The Bose and Sony sound good but not B&O or Sennheiser good. So far so good but will update if changesTook us about 20-30 minutes to replace I?m pissed that the return policy through Amazon expired way back in January, and I?m pissed about the disconnect between a manufacturer and Amazon customers. They do not hold up well and fall off easily.
