In principle, this does not matter, but it consumes unnecessary power when switched on. The device connects to the smartphone within seconds of being switched on, so it is not necessary to leave it switched on. I have been using the device for 3 years and am very satisfied with the battery performance - both of the headset and the "charging station".
To wear the headset on the other ear, turn the microphone boom around,
so that the earpiece is on the other side: (page 7 in the manual).

I wear the headset with glasses and have never felt uncomfortable. But I only wear the headset when I use it and not permanently...but without any problems for up to 2 hours at a time.
