I tried with a couple different ports on the back as well (USB2 and 3) but nothing helped. I could not hear any difference with or without the cover. I like that it just has that soft hint of red going down the side. The wedge is the same as a patricia, but the top of the sandal is different and fits me even better. Li adoro. I love the fact that my feet don’t hurt in these but they are very heavy and after two weeks they are too loose. Very lightweight and flexible, i love the detachable cable that the earcup has, it can save you from breaking the cable in some cases if it catches on something, all in all - Best headphones ever. I mounted this onto a Honda Pioneer 700-4 SxS, and like it a lot. I spent a lot on these because I need comfortable shoes! Verwendung:Bevor man sie verwendet, lade ich immer meine Kopfhörer 1-2 Stunden voll auf.
