I know it says 8+ hours of use. The color is a dark and even oil rubbed bronze color. I?m able to wear these for hours without getting uncomfortable. Looking around I have seen a number of other people experiencing this exact same issue and no one seems to have been able to get any answers on the issue from Jlab. I needed an adapter for my headset to use it with my laptops dock. 5 in all shoes but my heel barely fit on the end of a medium. Glad we got it, iron look matches well with the cast iron grates on our push in range. Größe Enttäuschung. Habe vor Jahren ein paar Kopfhörer gefunden die für mich perfekt passen, die DENON AH-D1001 welche mittlerweile nicht mehr hergestellt werden und vor kurzem dann doch endgültig den Löffel abgegeben haben. I?m very happy with these.
