I have previously used about 5 plantronics, bluetooth version 1.0-3.0, love it; but, not this one!
This Plantronics has sensor to turn off once I remove it from your ear. The sensor may not work very well. Once I disabled(off) "Smart Audio Transfer" in setting/sensors&presence, it seems to work, but not much better, microphone still sounds so far away. I don't want to play with all the sensor setting, someone might have better luck.
I download/install the software with my windows 10. I run it, plug in headset, then it ask me to download update; once download complete, you can play with settings.
