The use takes place on notebook with iPhone compatible headsets from AKG and Bose and the iPhone 5s. The plugs go quite hard to put what is good, but it must be noted, as in not quite complete connecting the microphone transmission / control is not active, there are connected then not all 4 poles. Unfortunately, the plug will not fit into iPhone Cases whose implementation a small diameter (= the original Apple headset plug) has, which is a shame, but not tragic. Overall, the quality has been very good and the cable has good strain relief of the plug and socket. Long-term test is made.
