Reception:
good to sufficient nat. not 20 meters indoors, but certainly 10, that it happens that the connection while hiking in the office or apartment separates you but it gets immediately from the headset by pleasant female voice informed "Phone 1 disconnected" and usually put them step back and it then connects each time immediately felt in less than one second - even when turning and in general: I've never seen such a fast connection to the paired devices! Therefore, here is clearly 4 of 5 stars! (A withdrawal, since the range nat. Still could be a little better, but hey, it's still for Bluetooth and the battery lasts a long time!) :)
Acoustics
Perfect! Best sound I have ever experienced. However, I am also not a fan of in-ear Kopfhoerern and therefore I do not have any comparison to equally high quality mini speaker techniques. My interlocutor both confirmed consistently me she me so well "than ever before!" understand myself - what more could you want? Even the Wind Shield technology on the bike working properly. As random even the MP3 player was launched through the headset, I have good amazed - what a rich and incredibly good sound! 5 of 5 points!
Handling
I like best the bracket to pull out and turn on. I even have a Tragebaendchen attached thereto so that I can wear the headset comfortably around your neck and it immediately with just one hand lands from there on every call in the ear - no problem. The battery life is also with 10 hours Gespraechszeit for more than a day is sufficient and with a push of a button on the "main key" gets you always announced immediately the remaining term - very convenient! Similarly Lautstaerkeregelung is blind palpable thanks differently shaped switches, which can be arbitrarily tilt even if you want to wear the headset rather right or left - and a well-rounded, again 5 out of 5!
Design
I find it much better in appearance than current competitors and it is just as hard and top-quality workmanship and the feel as I had imagined it before ordering. It's simple and not too pushy with thick logo, etc .. The idea with the on and off switch is awesome and is also wonderful to a tape to fix it (then even goes out still!) - I like the small part not to miss and do not know what you could do it better or more beautiful - OK, maybe even more stylish materials such as carbon? 4 of 5 therefore "only"! ;)
Practice
Round mega fit! It just works. No frustration when making calls, instant connection, best sound, practical design, holds bombproof in the ear and Ruck Zuck is attached with only one hand there! Battery lasts more than long enough and it can even be active 2 phones coupled. Assuming here 2 x Dual Sim phones to get to 4 active lines! : D - My conclusion: the money has more than paid off, thank you for the great product, great pleasure again!
5 of 5 stars total!
