Very disappointed with these headphones, I who had yet OMX680i the old version I have kept more than 3 years and were nearly perfect I expected at least as well! Disappointment after only five strides Small jogging, headphones always fall from my ear. I have to get out the cable of the bow and shoot it to get some kind of support.
By trying to remove material and make them ultra-light, Adidas and Sennheiser have probably forgotten that what holds a hoop around an ear is both the form that a minimum of weight. To believe that they tested them on any sports practicing a dynamic activity before marketing them.
