Video at Amazon.com: class headset that really hardly noticeable, but if only with its elegant design. Connection to mobile works simply and properly, the battery lasts for several days and the easy operation via the small button on the headset goes well out of hand. Sound quality is great so far, I would even use for listening to music, and about the Sprachqulität I have to my surprise so far includes only positive. All in all for this low price a great, robust and quality product. In addition still very fast delivery. Gladly again!
