I had found a metal quality to replace the original but it has had the same problem as his predecessor and another plastic adapter Fnac ... after a while, the thread is on the way, we is tripping over the wire and inevitably, the connector is twisted as it is rigid ...
So I was looking for a jack with a normal cable to the large jack adapter and this is exactly the scheme of this cable. No bad contact, already a good point (you could not say the same of that of the Fnac, while it is three times more expensive ...), quality construction, sound reproduced perfectly. It's all good, I recommend it!
