Sound quality is decent, microphone quality is decent, microphone setting is good but a bit picky about the volume and I often had to hold the microphone directly in front of my mouth raise my voice (a I have a loud Voice). It's really nice to be able to mute the mic and flip it down to unmute it. Unfortunately it was a headphone failure. After only 2 months of use, the mic detached from the headset when I turned it over during a call, just holding on to a tiny wire. I have a desk mic and other headsets so I just unplugged the mic and can still use the headset but I was very disappointed with the apparently poor quality of the plastic used.
