Of the two, I'd say the HyperX. If you're open to outside suggestions, you can look at the HyperX Clou(I, the first version) or Thermaltake's Level 10 headset. Provided you're looking at analog connectivity off your sound card.
The fact i'm on a budget and the two seemed fine for the price. I checked the specs of the two and saw that the SteelSeries had a highest/lowest frequency so it must sound better but i needed to check for the real life performance of the two.
Definitely the Steelseries. I had a Steelseries Siberia V3 which is basically the newer, and probably cheaper option. It was extremely comfortable but I broke it by dropping it from 6 feet while I was wearing them... I bought a Cloud to replace it and I didn't know how much "normal" headphones hurt my head with the pressure because I was used to the Steelseries almost 0 pressure on the top of my head. Most comfortable pair I've ever owned
