I had bought the stretch for the first time in early January and had then carried him really every day in everyday life and sports. Already after 2 weeks the extension cord is broken me at the audio input. In the 2 weeks of the headset has been treated with care and there was no massive vibrations or the like. Have the headphones after exchanged immediately and brought me the same again. 4 weeks later the same, again cable break at the same point. For a headset is touted for its stability and also for his "special" cable, this is in my opinion simply an impertinence. From cheap headphones I know the problem with the cable to the audio input, but for a price of just under 100 euros, I expect something else. I have now bought a new extension cord (from another supplier) and was able to resolve the issue.
The remote control only works for iPhone 3GS upwards, 3G is not supported.
Bottom line: sound, comfort, optical super - processing of the extension cord is absolutely deficient.
