This has a lot of space. Thats my only gripe The unit comes with a 3. Ive been wearing Reefs for decades and Ive never been disappointed, so maybe its just this particular model, but if your feet are even the tiniest bit damp, the bottom of your feet will slide ALL OVER the top of the sandal. Size is snug at best. For mastering, or in my case ripping from vinyl, you?ll hear every detail and nuance on a well structured and open sound stage. I like them but they will be only for summer quick trips to the grocery or out to eat at a casual beachy restaurant. Did not work for Arctis 7. Im an attorney and I needed a way to hang extra blazers, suit jackets, sweaters, and even my big winter coat in my office without it looking tacky. A bonus is that I might be extending the life of my bar and handles.
