What is the best Headset or Mic-moddable Headphone I can get for awesome sound?
(Mainly used for Arma3 and EDM)?
If it is a Headphone, please specify the microphone add on and any mounting techniques to the best of your abilities.
This isn't particularly budget constrained, but please don't mention anything over $1,000 USD, because just no.
Thank you for your time and your patience.
That's an option - it's cheaper than the premium gaming branded one. And it sounds pretty damn good. (if it's the DT150, bit with just a mic on it, which looks like it is). http://north-america.beyerdynamic.com/shop/hah/headphones-and-headsets/intercom-broadcast-and-tv/headsets-for-intercom/dt-190.html
