Unfortunately, one morning they were working in stereo and then I only had sound coming from one earbud. I have slender, size 5 feet, but if I had flat or wide size 5 feet then the size 6 wouldve been perfect. This wheel set came with ABEC 7 bearings installed. Obviously we havent had it long so I cant say much about longevity yet, but the sound coming out of it is downright shocking, in the best way possible. Despite this issue, the ear pads on the Sennheisers are soft and the headsets light enough to make them comfortable. Original review: I wore them running once. There is no tongue like a normal shoe so the laces seem more like a decoration. I would recommend them, but dont expect a perfect fit initially until you wear them awhile (a week or two). It is cute, but I wish this didnt happen so soon. Compared to the Bose portable home speaker the cost is $499 but it also includes a halo shaped charger that is very slim and sits on a desk or table and all you do is simply set the Sonos Move in the dock and it will start charging.
