I recently got these headphones they are very good apart from only when I watch a video with talking in it there starts to be a background buzzing noise, it's very faint but I can still hear it and it can be annoying. The Hyperx cloud 2 come with a small external sound card, but I was thinking of getting a better internal one, but I didn't know if I can use a sound card because there is only one cable that is used for microphone and speakers there isn't two separate cables so can someone tell me if I can use a different sound card, even if mic and speaker are represented by one cable.
