Summary: The sound quality is decent, no real noise, its plug and play on win 7+, no extra drivers needed, the only problem is that the head strap is tight it presses into the side of your head which is bad for any long periods, well in fact i felt it hurting after a short, so ill probably not be using it much..
Summary: Bought this as I had received a PSU that wasn't working correctly. It immediately identified a faulty power rail, so could now return it. Bought a different unit and was able to ascertain it was workign correctly before connecting it up to my motherboard, etc. Great unit, easy to use and works.
