rather bad for a Sennheiser (PC8 USB headset)

The headset had many advocates but unfortunately, I can not understand that. From the great brand "Sennheiser" I am used to better, so my verdict with only three stars out rather badly. Nevertheless, three stars, since the function and description agree.
Per
- Easy
- Microphone on cable Stummschaltbar and volume control
- The sound and music quality are ok (Stereo)
- Ironing size adjustable, characterized by its light weight and does not press the headset on your head

Contraindications
- Very thin cable that after 4 weeks of use (several hours a day) aufkräuseln still be, that my was I, that the cable is still wound in and turned on the headphones moored
- Micro voice quality is very poor and not at all what a headset is feedback. This is something I've never experienced and it would not have thought of Sennheiser.
- The entire headset feels very plasticky and cheap.

I would not buy this headset!
No purchase recommendation
