Summary: This obviously does not have a sound card. Basically what you have is the complete headset with an inline controller, with a retractable microphone, and that's it. Though I had to RMA a pair of headphones because the computer didn't recognize it the first time.
Pros: Great sound Awesome fit Push-button controls, as opposed to the potentiometer control or sliding switch which get rusty when they're not moved around.
Cons: None that I'm physically aware of, apart from not being able to curve the microphone close to my face.
Summary: I reviewed this product after one day of ownership, praising its sound quality and supposed durability, but lamenting its bulk and size. http://www.newegg.com/Product/SingleProductReview.aspx?ReviewID=4062418 9 months later, my thoughts have changed.
