I have one of these and it works great! The only problem is some times you here a buzz in the background when using the mic. Besides that this product is comfortable and has great drivers.

Nothing fancy and gets the job done. Have had worse and have had better. For the price $30.00 at Officemax not too bad. I have had an issue with the microphone and the volume control. Will see how the warranty claim is handled. (just over 1 month old) Not complaining about the quality as things happen, that is why they have warranties for issues like this if and when they do arise. Will post on update to how the warranty claim goes! But all in all would give product 4 stars so far.

the headset itself is wonderful, i just have an issue with the seems that when they update the driver becomes corrupted and/or lost somehow and the headset becomes unrecognizable to the system. It's fixable by removing the headset from within the system, but it is really annoying :)
