Great product. Makes a Big difference than "HD 8.1 or 7.1 or 5.1" or what ever you have as On Board Audio!.
I thought I had great sound in Battlefield 3 untill I risked it and popped this in. A world of difference.
If you're tone deaf and don't care, don't buy it, but otherwise the audio quality difference is tremendous!
One word of advice if you haven't already read in other reviews: don't struggle trying to disable Audio
Drivers like the manual says, instead just diable ON BOARD Audio is BIOS prior to doing anything else and your install will be flawless.
Must have Windows 7. Box is misleading about XP compatiablility!!
GREAT PRODUCT if you are a gamer and love music. I can't comment on microphone functions (good/bad) because
I use a USB Logitech mike. This has Analogue mike jack input.
If you want ultimate, supreme, super AUDIO/SUDIO professional product and are not a gamer this is not for you.
The next model up has identical Specs plus a red LED light and a microphone included. Same guts though.
