der Bügelverstellung und die drehbare Achse der Ohrmuscheln aus Metall gefertigt. Very pleased with these, well constructed giving a very stable shooting platform. Wore them for 2 hours and they actually gave me black and blue bruises from the tight leather. Pros:Sound is great with good fitment for me and HD sound when enabledGood voice call qualityMono Modebattery lifeCons:Case is cumbersomebuds hard to take out of casebulky case for the size of the buds This product fit. I was not satisfied with the comfort of the in-ear. There is a thick layer of cushion and I think they will last quite a while. The rack is very solidly made, bolts securely into the wall studs. I bought it for my mom whos a little on the bigger side and this dress looks great on her. I?ll let you know when my STD test comes back, but until then, keep away from these shoes
