1 audio is so much more accurate as well as much crisper and cleaner sound. In the past Ive had these but always brought the refurbish ones for like £20ish as people recommend them. Im honestly blown away at every aspect of this fan. 95; that is a phenomenal deal compared to the price of $80+ on the Keen website! Plus, I?m certain by the time I went to box this up and I?d have to get shipping tape, run to the UPS shilling store, the replacement one most likely would have the similar issues and all that would?ve been for nothing. This one got great reviews & people said it was smaller than they expected, which is perfect for my small bathroom. Amazon renewed phone. Its so difficult to know what size to order, I wear a 10, 10. See before and after pics. Very uncomfortable.
