Good place for headset

I bought this glass head kept a little better to my Roccat Kave. The workmanship is good. But unfortunately you can see in the middle of the head but already clearly a seam. Otherwise I can not see any material or manufacturing defects at my glass head. What else do I have to complain about is that the eyes look a bit strange, so I've also covered with a red-cyan 3D glasses. Amazingly, it looks even quite good ^^. The My headset ausleiert or the earpieces are deformed, I now can not observe.
