I have a part now for about 6 weeks. The positives first: Undeniably a very good sound and very pleasant to wear. It is the first in-ears that I had three hours at a time in the ear without pressing somewhere. Also positive: Finally a cable that does not get tangled constantly! Now the negatives: The included strap (If something sportier is) unfortunately disintegrate after just four weeks. Here I have not even used, but always carried around only in the transport bag with. Something I did not expect at this price. And the service is rather hard to reach, slow and cumbersome. So far, at least I do not know how and where can I get replacement.
