However, there is a bug ...... I am my headset since November 3rd 2012, (comment 21 January 2013) The first headset died when I made the language change, 10 November. Replacement within 24 hours by DHL, very good service. 2nd working but a problem of "firmware" was that it was not possible to change the language. 3rd received in early January 2013 - due to out of stock !!
If you're lucky (and not bad luck that I had), you will be very satisfied with this headset, which I consider better than the "Jawbone" and other ear that I had. If you have concerns, know that the service is excellent and the follow great, (as long as your product is in stock !!)
