tbh man gaming headsets aren't really that great

But If you still want a headset of some kind please consider this.

And here are some good headphones and here and here.

But if you still want one of those two headsets you mentioned then fine. Its your money man. Whatever makes you sleep at night. The Steel looks like your run of the mill headset. The Sound Blaster looks kinda interesting but the features sound gimmicky imo and looks kinda tacky if you wear it outside. I have bad experience with wireless headphones tho.
