I have the call of duty black ops 3 astro a40 headset for pc. and I thought they were 5.1 channel audio. But when I hook them up to my pc there not. So I'm gonna buy new headset. Should I buy another gaming headset or should I buy some expensive headphones that are made for listening to music like beats or etc? Also, I'm gonna use them for heavy gaming and that's it . I don't play online so I don't need a mic. Also, I'm not on a budget so I don't care if there expensive.
