Just got mine today and for the price I paid ($25) they’re OK. I must say the drivers suck and in no way will I ever use them again. The first thing I noticed is when I click on something instead of hearing the familiar click sound it was more like static. In fact that is the best way to describe all the sounds you hear no matter how I adjusted the settings. The only reason I tried them in the first place is because there isn’t much bass and my sound card drivers wont see the USB headset. The microphone volume went down and the quality went to crap too. Just stick with the default windows drivers the quality will be fine. I can stick use default windows drivers and live with the lower bass for now. I’m sure I will be able to fix the bass issue with little effort.
Because of the large vent holes on the sides they aren’t very good at keeping outside noises out and people around you can clearly hear what you are listening to. I don’t know how these would work in a noisy environment but for home use they would be fine unless you are near say a loud TV.
This is also the first headset with a microphone I have owned so this next small issue may be common or just a USB thing. There is a switch for the Mic and when you turn it on, it is always on, even with the supplied driver. That may be why they drop the volume down, I don’t know. I just find it weird because my webcam has a mic and it only works when a program tells it to.
All in all though the headphones seem good but I’d just go with the regular set rather than pay $10 more for USB unless you don’t have the Mic port to spare. The only difference between the two models is the USB one has an adapter with it.
