This headset will give you horrible sound if you use an on-board sound, Realtek is not a sound card, that is on-board sound and it will not work at all with these headphones. All the negative reviews and low ratings for this product are false. People don't understand that these headphones require a sound card.
Step 1 > Get a 7.1 surround sound card. Step 2 > Install it on motherboard. Step 3 > Connect headset to Sound card.
Done, easy as pie.
If you can't do that, get the Razer Kraken Edition.
