We calculated we walked over 70 miles during the week and to have no pain or fatigue is just incredible. They connect quickly in stereo mode and in mono, individual mode. I get so many compliments on this dress! I would definitely recommend these and probably wouldnt size up, as they stretch out quite a bit over time and end up fitting your foot perfectly. I have never once had that problem because the magnets keep the wires straight and untangled. All in all, great product for the price. I purchased this a few years ago and found that the devise felt heavy in my ears and hurt sometimes. The old coffee table was an old military grade table and I wanted to replace it as a parting gift to the office. The touch controls are very responsive compared to a bunch other budget earbuds I’ve tried. I never find myself running low on charge.
