You may or may not want to go to the shorter half size of your usual length range. They may as well be open-back with how much sound they leak even at low volumes. Wearing them already. These headphones sound great and they look great. The footprint of the desk is larger than I thought it would be, but thats only a negative because Im operating out of a small space. I love that these are slip-ons. 5 is a number 9. I consider my ankles to be a little bit large and I wear an 8 wide in tennis shoes. I was a little nervous based on the price but Im happy so far. My pair are the narrow fit and are on the very last buckle hole of the strap.
