I've been having Logitech G230 for almost 2 years now and I'm not happy with them. Sound quality is mediocre, but I get a headache after few hours and also microphone is not as good as I would like it to be.
I've been thinking about buying Siberia V2, since I've heard good stories about them from your videos, but I've never noticed you never saying anything about its microphone. I would like to have a less background noise as possible. Price of V2 has also dropped by a margin, when V3 came out. I use microphone wile gaming only, but I can't have microphone catch any keyboard button pressing or anything else.
