For this headset I've made my decision because the good Kofhörerhersteller unfortunately produce only for iPhone (other pin assignment) and the smartphone manufacturers sell the phone only inferior headsets. This limits the selection did not quite. Since I the telephone also for listening to music using me was a good sound important.
With the sound and the design of the headset (asymmetrical cable) I was very happy and could see no difference in quality to the old Senn hoarse.
That the sound of In-Ear Kofhörern is worse than with ear umschließenen Kofhörern should be clear, especially if at that come ambient noise.
Why then still only 3 stars?
The adapter is unfortunately far too clunky (see photo) and has now led me to the cable break because the cable is much too strong bend in your pocket. This could have been solved much more elegant.
Why is there no high-quality headsets that work directly with Android devices?
Conclusion: Should be the headset for Android: Hands off. Otherwise, the price / performance ratio is absolutely top.
