I use the device primarily for cross-country trips and in city traffic, the phone I close the windows and turn off the radio, thinking the argument that the environment was louder than for the device does not work here before.
Nevertheless, my understanding of the interlocutor was usually very miserable. One must partially repeatedly ask, which of course not exactly in the opposite side makes for enthusiasm.
My interlocutor reporting problems with feedback, also the device has a tendency to oversteer strong, particularly on the last 2 volume levels. This is particularly annoying because now even a certain noise when driving there, so you have either the choice, nothing to understand, or try to from the crash rauszufischen the words.
The phones were used alongside a Motorola Defy + with current Android CM also an old Nokia N8 with Symbian Belle, so once Stone Age and even so new that the bits are not even cooled.
When using the Jabra I could not detect any significant difference.
On the plus side, the Bluetooth connection was with the Jabra always easily and without disconnections, only once I had to re-pair because it was no longer detected from raw agree reasons as telephony headset device.
My personal conclusion:
Either invest more money in a proper condition, or if you want to stay in price equal to adopts headset. For the same money you get a -viel- better voice quality and also as the possibility to voice dialing, which has with me always works well.
(My comparison is based on a Plantronics headset that I have "misplaced" Unfortunately, recently, to the extent to the detriment of the little things.)
