I have had the GN9350 for 3 weeks now and the call quality is great! People do not know I'm on a wireless headset. I have only wander about 100 feet from the base but, it has been in a house so, the signal has had to go through walls and I have not been dropped or had call quality issues.This headset is compatible with many forms of communication hardware and software. Because of this, it gets a little confused as to what it is supposed to do in a given situation straight out of the box. It can be adjusted but, it takes some trial by adjusting the headset and your particular software to get it dialed in. If you are not tech-savy, this may get a little frustrating! If you do take the time, it works as advertised.
