I’m sorry, I missed this question in my pile of Medium replies!
Both of the headsets I talked about in this article use a standard 3.5mm connection. The Cloud II also includes an optional USB sound card. The cable on the Cloud II isn’t that long, so you’d need to use an extension if it doesn’t reach your case.
Of course, if you’re not planning to use the USB sound card, I think the Alpha is the better buy! I’m also not a big fan of the card.
