I have a Hyper X cloud 2 USB headset. I want to upgrade my sound and Microphone quality. Will this be a big upgrade if I go for ether sennheisers. I own a MSI gaming 6 Motherboard so to anyone that knows I don't know if the sound will be decent if I directly plug into them. the Pc version comes with USB , would it be an upgrade if I just leave the USB on them. If go for the HD598 I'm going to probably end up getting a sound card from what people are telling me then a mod mic or a separate desktop mic. My uses for this are gaming, Music and Movies. HD598 is $150 and Pc363d is $200
