We paired it with 4 strong magnetic hooks and it was known as "The Wall of Wonder" - the walls of cruise ship cabins are metal and magnetic hooks attach everywhere. The sound from these is delightful - as would be expected. I get lots of compliments all the time. Yes the noise cancellation is very slightly substandard to the Sony?s when side by side testing (though still pretty amazing) and they aren?t as loud, but they are the best for all day wearers. The mic button works, and so does the volume. No rubbing or blisters even if my feet swell during the course of the day. I wish the straps were a little longer. It also comes with ankle straps, 2 handles, a door anchor, and an I struction booklet with a detailed description of different exercises! We really love it! Only time will tell This is a very nice sandal , so your experience might be different, as far as the comfort level goes.
