I've used quite intensively the last few days and the battery level is still high (thanks to voice message when turning is always as informed). My expectations of the battery have ever exceeded.
Call quality is good, as long as you speak clearly. The recording quality is better than that of my smartphone or the built-in microphone on my laptop. My counterpart understands me always good and the noise reduction works. A pleasant conversation is possible over a long period.
After switching on the headset needs can start up a conversation just a few seconds. So that should naturally be.
The volume control is used to, as spoken and silent switch are not separated. So you turn on the volume button always by 5 volume levels (from very quiet to very loud) and then starts again at very softly.
The headset can be proud and wear. Small and lightweight (plastic and plastic flat), it is well on the ear, discreet LED display and modern design.
Actually, I wanted to get rid of criticism in this review, because I could not seem to connect to two devices at the same time the headset (it was connected, I had the connection only separate the then restore with the second unit).
But what I see in a review ?! Even MULTIPOINT is possible (when you turn the headset call button hold)! Discovering this function (I thank them R. Springer and Chris) makes this device perfect for me.
Finally, we can only hope that it also holds some years (my old headset after one year had a loose connection). I'll keep this review course, up to date, if there is something to report for durability.
5 stars for the headset, because all expectations were met. For this price you can not go wrong does.
Nevertheless, the suggestion: The multipoint function should be mentioned in the enclosed instructions, or at least in the product details at Amazon.
// Update (November 2013): It runs and runs and runs. Despite very intensive use the headset calls rarely for electricity. With a charging cycle can still achieve a comfortable talk time of approximately 10 hours. I have it connected to a wide variety of devices and never had any problems. There is simply nothing negative to report!
