Property me now the 4th generation of Midland bought and getestet.Die quality of materials as well as the speakers are alright. The built into the helmet, and the establishment outside the "dock" at the helm worked perfectly. By and large, with all the functions are easy to use and it does what it should. As for the range of 1.6 km, the boys and girls of Midland obviously tested in Salzwste where no Lftchen blowing and there is nothing else which can interfere. But I do not mean to complain about the coverage was in my test about 800 meters with the best weather and soothing 33 degrees and 120 km / h. We drove on a perfectly straight road in sight. The voice quality was good. Otherwise, as I said, it does what it should. Have a GPS GARMIN connected and a phone Samsung Galaxy S3 Mini. All functions in the exchange have played flawlessly together and control over the Midland headset worked fine. Also the call and then switch to intercom worked out fine. All in all a recommendable device that makes driving safer and more enjoyable!
