I use this headset in the office mainly for listening to music and isolate me from the landscape. As with VoIP calls and conferencing via Cisco softphone or Lync. It's a little warm ears which makes it uncomfortable for long periods of time (2 hours max I would say). Otherwise the sound proofing of the atmosphere is just OK. The sound is good and my callers do not complain about how they hear me. So the microphone must be correct also for this purpose. Finally the brand and the look make me stand out from my colleagues with their low-end Logitech ;-)
