Only sound from a speaker - again this defect!

This is already the third Sennheiser headphones in which this problem occurs. Had really hoped that Sennheiser provides the remedy. My old Sennheiser me were exchanged in the guarantee (cable break only one speaker). The new headphones were then PX 200-II without the controls, since my old were no longer available. After about 1.5 years of intensive use the same problem / the same defect has occurred at these headphones. Since I had no guarantee, I have the PX 200-II i done to simply use my phone even while jogging to me. After about half a year use can occur here again the same problem. That is, music comes only from a speaker.

Conclusion:
+ The sound of good headphones, which works great little shields and especially when Sportln with the remote control (music changes).
- Due to the recurrent problems with (I'm at least assume) cable breaks, the headphones fail the service or only sound unilaterally at any time (even after a short time)

Recommended Sonically, but I would look for another brand, because this model in my eyes has no longevity. In addition, these are not very cheap headphones, in which a defect would be to get over.

2 stars Good sound, comfort and impeccable service (at least with the iPhone)
