I had several different adapters from other manufacturers in use, which always held just a few months before the insulation broke up and then eventually released were the copper cable or completely torn through. Not so with this adapter. On the one hand the angled connector prevents kinking in the trouser or jacket pocket, on the other hand, the adapter is significantly more solidly than the copies previously used by me. The slightly higher price is given the better quality totally justified. Those who like me is annoyed about the short shelf life of other adapters, which this is recommended here. Also the microphone and button for answering and ending calls or starting and stopping of media reproductions without problems.
