Can what it promises, unfortunately prone to broken cable

I had bought the unit, despite that already in other reviews of cable break was talk. That now seems but unfortunately the product failure that occurs not only in individual cases. The return period of one month had just expired, now therefore I turn to customer support from Sony, which previously designed is effective.
Despite the good support, as one may expect from Sony, I can the product not recommend it, because such defects are likely to occur only at unpfleglichem use, I have my headphones but always treated very cautiously (last wired headset from Sony worked for more than comparable products from other manufacturers> 4 years)
