The microphone worked very well.

It's significantly louder than, for example, an iPhone speaker, and the microphones seem to work well

The 2 main reasons are the better microphone and music playback

But the microphone is absolutely dismal

Just connect it via USB or Bluetooth to your laptop (or, I would imagine, any iPhone, iPad, or other device with BT capability), start-up Skype (or your phone or other VoIP app) and select the Jabra 710 as your preferred microphone and speaker for the call(s) -- and it works PERFECTLY!

Great microphone, great voice reproduction, great volume level.
