Pros: It works fine even with heavy load. It easy to carry around and sturdy enough.

Cons: None

Overall Review: It could have another type of usb connector in the disc, since the one that it uses tends to brake more easily than others.

Pros: It cools the right amount and you can change the fan speed. My laptop (15') fits without problems. And even playing the Skyrim with a lot of graphics enhancing mods, it keeps my laptop in a good temperature range.

Cons: None.

Overall Review: It could have the USB port on the side instead of the back, since the usb cable that it comes with it's really short.

Pros: The sound is good, not too good, but for the price(i paid it $10 on sale) you get actually a really good sound. It fits right and it's comfortable, but if you use it for too long (like more than 3 hours) it will start to hurt. But if you take it off a little bit, you can use it again with no problem.

Cons: The play/next/last song/answer phone button is not very sturdy and sometimes it seems to be pressed, but actually is not pressed at all.

Overall Review: I think it's a really good headphone if you get it on sale. The full price it's too much for it's quality.
