Plantronics Voyager Pro UC Bluetooth B230-M Headset with Dongle only $97.90, regular price around $155
Wow! What does this little, light-weight unit not do? Dual mic noise-canceling, WindSmart, Wideband, AudioIQ2, Multipoint and digital sound processing.
Sounds like we're just making up names now - what all of that means is you get the most incredible call clarity both in the office, and when you're out and about - irrespective of how noisy the surrounding environment is.
This little guy also connects both to your mobile and your PC (via the included USB dongle) and you can switch between receiving calls on your PC and mobile with just one button.
This model is optimised for Microsoft® Office Communicator 2007 and Lync. But will work with other vendors as well.
Save me some time googling: Is this v1 or v2?
+1 for quoting regular price comparison as opposed to RRP.
