Today I got a new mic I ordered (it's USB and not 3.5mm thingy) and it keeps disconnecting every now and then. I tried multiple ports and it also has really, really terrible audio quality. It sounds like a legit 2 dollar mic. It was almost 30 bucks and I've checked some youtube videos on it and afaik the sound quality should be good.
I think both problems are software problems.
Anyways has experience with USB mics and windows 8.1?
