Summary: The sound is great and the mic come through clear, however the ear peices were not made for extended use and i would not suggest buying this if you plan on wearing it for more then an hour or two.
Summary: Don't go cheap like I did. Get some real headphones + mic.
Pros: I purchases these back in July. I literally plugged them in and listened to some music to make sure they work, but I didn't get a chance to try the Mic. After moving I pulled these out to use the Mic on steam. The mic is shorted out with loud popping every time you move your head. Outside newegg return, and Koss wants me to pay the shipping both ways.... Last Koss I ever buy, not even worth the shipping ($9 each way).
Summary: I will be buying a different headset asap, and wish I could get my money back for this one
Pros: Fits nicely over my ears.
Cons: The sound quality is horribly loud. I have to turn the volume way down on my computer whenever I plug them in. The mic is absolutely horrible. I sound like I'm talking over cans and string tied together.
Pros: They are cheap, the mic works well when its not messed up
Cons: They are cheap, the microphone easily gets shorted out because of how they built the wires into the side of the headphones and Koss charges you 9.00 plus you have to pay shipping there anytime they break you might as well buy new ones so the lifetime warranty is bogus and not worth using on these cheap headsets. My microphone went out less ten a month after I had them and koss wanted to charge me 9.00 plus I had to pay my shipping there which was 10 dollars not worth ...
Summary: The main reason I bought this is for the mic, and well, I am sorely disappointed because it doesn't even work! I should've spent more money on a higher quality headset. If your pair arrives with a working mic, then you are lucky!
