The dip bars are constructed very well, with a nice weight to them. The compression of bluetooth obviously didnt help either. Of that short list, the K712s and the Focal Spirit Professional headphones cost more than I cared to spend, and the frequency response curve of and DT-880s were not as tight as the AKG K701s and K702s. The Sony is every bit as great sounding as of the same build quality as the Soundlinks for a lot less $$. Nothing worked! It also fell over if you did not place and balance the bicycle in the holder carefully. I am very satisfied with these slides. I ordered bigger size and now my feet are within the sandal and the strap is loose so that it is quick to put it on and off for impromptu trips to outside or basement. I can no longer wear them with socks and struggle to get just my bare foot in too. On the bright side it looks okay if you dont use it for what its meant for.
