Sound is not all - zero stars would be attached!

As here many times commented, the headphones have a super sound and rich bass really has to offer.
That was it but unfortunately already. The so-called headset is not to be used as such (have it on Galaxy S3 and S4 tries).
Part 1 - call:
Answer: sometimes goes, most of the call will be but 'rejected'.
Ending a call: Works. But the display of the mobile phone that you precisely when you hold a headset does not use in hand goes on here. And all the keys and functions on the screen are then merrily in your pocket 'pressed', such as 'emergency', a (false) PIN input etc. What a Bulls ***!
Volume buttons on the headset: No! What pray tell is that supposed ?! Is not that the elementary function in a headset? They want but just not at the device must fumble around in your pocket! And at the sales figure that can not be seen, let alone that it is in the description.

Part 2 Music player functions:
A song continues: Only works very unreliable, usually the 'double' as pause / play is recognized. Very annoying.
The lack of volume keys I mentioned ...

Part 3 processing:
Miserable! after less than a week is the rubber sleeve, which forms the transition between the plug and cable, have been already broken.
None 3 months after ordering the earphones now have their service fully acknowledged - the headset no longer is, (caller does not hear me), and when listening to music, the volume control on the phone constantly running up and down.
Get this junk now claim - rather spend a few euros more ...
