I'm just using a single IKEA Adils leg to support the center mass of the Karlby. I have good feeling it'd start to warp without it.
The headphone stand is just a Omega look-alike from amazon (https://www.amazon.com/Qadira-Wooden-Headphones-Stand-Hanger-Holder-Walnut/dp/B014F37W9E)
Because its kind of an expresso finish and it doesn't exactly match the rest of my walnut themed setup.
I have a https://www.amazon.com/Qadira-Wooden-Headphones-Stand-Hanger-Holder-Walnut/dp/B014F37W9E/ walnut headphone stand and it doesn't even resemble it imo.
Found it on Amazon a bit pricey!

It's not available anymore, but you should be able to find something similar on Amazon
So I guess it wasn't $10 but still:
You don't need a hardcore case for them to be honest, you could buy a headphone stand and just keep them on it when you're not using it.
Something like this should be preferred because the HyperX Stinger doesn't have detachable cables so you'd allow them to just freely hang instead of being bent on stands such as this one
You can get the fake ones on ali or amazon for like $40.
The real original Sieveking Sound Omega Heaphone Stands are like $180.
I have had both and returned my Sieveking because it was the same identical one to the one I bought on Amazon.
