Unfortunately repeated cable break

Actually I know Beyerdynamic as company with high quality standards. The sound of the headphones I like very much. Defined, but not overpowering lows, clear mids and highs good. However, has occurred to me that what has been feared in other reviews: The cable is broken after a month use, resulting in a wobbles on one side, who appeared at every small cable movement. Although I use the headset each day for about 2 hours - but that may not happen as quickly. So quickly replaced the headphones - is indeed very quickly and easily on Amazon. But even with the replacement headphones is exactly the same phenomenon occurred after a month, so I've been buying undone. Too bad, because the sound, the size and the price have actually voted.
