Arctic Nova Pro Wireless Headset. I can stay connected to both my workstation (with enough range to cover my house and some of the yard) and my phone at the time. This allows me to wander/pace away from my desk during meetings, and also answer calls without taking it off. It's super comfy, and comes with two batteries so the base can charge one while the other is in use, so you have to plug it in to charge. The quality is pretty good (not as good as my Sennheisers but good), and the battery compartment has a thoughtful magnetic catch instead of a bit of plastic that will break off. The styling is muted and not super "gamery".

It's a wonderfully designed piece of kit and I highly recommend it to anyone who works on a computer or is a PC gamer.
