No problems! Light weight. Equally comfortable but not expecting them to last as long as huarache as cross straps stretch a little each time I wear them. Very happy with the result, and the Barfly mount has been carrying this heavy GPS over some very rough terrain all summer without fail. its just the sound quality is really bad for Sennheiser to put their stamp on. The tongue is attached on the sides to the upper, so it?s like a loafer with functional shoelaces. Two outputs for powered subwoofers (unchanged), much appreciated by me. I had to kind of squish em in, and even then, still had some side boob. Holds up pretty well I don?t load a lot of weight I like to go moderate so I can feel the muscle working. Full blast still crystal clear and the bass pumps!
