But sound class defective after 3 months

I would advise against these listeners, even if I find it a great pity! I'm actually a fan of Roccat products and apart from the transition from receiver to cable processing and the sound is great, but unfortunately just enough a single vulnerability in order to make the product out quickly. But here are the details:

Sound: Class! Can not complain. Good bass, as well as clear highs. It's really fun to listen to music with it!
Microphone: Good sound. For telephoning and VoIPen entirely sufficient.
Play / Pause button: does what he should. (Android phone)
Unfortunately, no volume up / down button

Cable: Nice thick, robust cables.
Transition cable jack: Also very good, very long and flexible protection against kinking and damage.
Transition cable listeners: Unfortunately very poor. The cable has game, you can move it a little in and out. If you come once to the cable and pulls it provided from the ears of doing the connection is not good! After about 3 months, the left earpiece was dead and the right had a loose connection. Too bad for otherwise good headphones!

PS:
Big plus to the Amazon support! Quibble and lightning-fast replacement!
