-Light Device
-Good Plantronics App's
-Sprachansagen The headset (also in German)
-Wahlwiederholung
Earhook removable
-Microfon, The people with whom I spoke on the telephone detected no difference otherwise.
What I do not like:
1. The headset is not powerful enough to operate it in noisy environments and in the car
1.1 Therefore, the volume buttons are unnecessary because the Max. Volume is recommended already.
In addition, my copy has a loose connection on / off switch, so I will send it back in any case as soon as the Sony MBH20 is there, because that will probably be a bit louder.
Addendum:
My expectations were probably too high. I ordered also said Sony. And have to say there are worlds between.
The Plantronics is:
1. much more comfortable in wearing
2. The volume is loud
3. The output speech is much clearer at Plantronics.
I have to give it seemed to me at first still very low, but I have caught me as I have found it quiet while driving with the first application itself.
That leaves little loose connection, as it does not interfere with the device in the function and I I'm the only one with such a time now would assume, I prefer considering the price is no point to the effect.
