The best feature of this product is its compatibility with all platforms (Xbox, PS3, PC and Mac).
It produces decent audio quality with deep bass however there is a slight hum which can distract you during quiet scenes. The build quality is average however within 4 months of ownership it has already succumb to the dreaded floppy microphone which is now unable to be raised and will just fall with slight movement. Even when taking its relatively cheap price compared to other cross platform headphone/chat solutions, I have trouble recommending this product. It does the job but If you're a serious gamer, you may be disappointed by the average performance and build quality of the product. I've heard good things about Turtle Beach from friends which urged me to buy the PX21's initially but this one has fallen short in my experience.
