Good wifi USB adapter and headphones compatible with windows 8.1 and USB 3.0

Ever since building my new computer my headphones haven't worked as well with windows 8.1 and USB 3.0 and my Wifi adapter is just not working as well as it should and I read that it was because of windows 8.1.

If anyone could help me find a good pair of gaming headphones for around 100 dollars, that would be great. I don't care about portability, but they need to have a good mic, be comfy, and sound better than the Siberia Steel series v2. I wear glasses all day and need something that doesn't bother me for hours of wearing with sensitive ears.

I also need a Wifi adapter for my computer, since I am upstairs and there is no way a cord can reach my computer. I don't know how much a decent one would cost, but I am pretty far away and the 40 dollar one I had worked fine, but I will be gaming and uploading videos etc. I don't really have a price range for this, but the last two I had bent really easily and were pretty fat, preventing me from placing them next to other USB devices without them bending.

Thanks for the help and remember, they must be compatible with USB 3.0 and must Be compatible with windows 8.1.
