The article is a "custom-made" from Bose and work accordingly with a corresponding Bose headphones. After I have done me an excessively expensive OE2 Headphones Bose and this was delivered with the same defective cable (which in this price range is expected to happen under any circumstances!), So I had to cable technology for replacement care. The price of this thin Käbelchen is simply too outrageous, but at least the work "earpieces" with the replacement product now works properly.
