My special drawback: the microphone is so far away that the called party does not understand me when I do not think it is high and it is easy zippelig and impractical and slipping ever - had with the original headphones previously never had a problem.
Only postitiv viell. That since I can connect later possibly other headsets by the coupling connector.
Unfortunately, there are hardly any alternatives ...'m irritated. Would prefer On-ear headphones to the ears inside not to irritate ... not easy ... too bad.
