Pros: Sound quality is pretty good. Mute function and volume control on headset is nice. Software was useful. Wireless. Battery lasts a long time. LEDs are cool.

Cons: Microphone input was always very low for me and couldn't be raised. You cannot hear yourself speak when using these, which causes you to talk louder. Microphone stopped working after 6 months. Headset can be painful on your ears after hours of use. The wireless receiver sticks out very far from your PC, which can be hazardous if someone bumps into it. Not enough quality for the price. If you mute yourself, you have to take the headset off to check if you're still muted.

Overall Review: These weren't too bad while they lasted, but after 6 months of basic usage, the microphone will no longer pick up any sort of input. The range of the wireless is pretty decent, but don't expect to be able to leave the room and still speak to anyone. When I was first starting to use this headset, the people I was speaking to would always tell me that I sounded really quiet, even though my outbound microphone volume was all the way up. (Perhaps there was a technical problem from the start?) Also, the earpieces would begin to hurt after several hours of use. The battery life on this headset is pretty great though, and there is a slight 'beep' when the battery is about to die. The wire for recharging the battery isn't too long, but it was long enough for me. For the price, these are definitely not worth it.
