Just some cheap acrylic one off of Amazon. Apogee or something?
I suggest taking off the box that style only works with certain setups and yours isn't one of them sorry. Just don't throw it away you'll never know when you will need it. As for something else try to stick with one color or colors that compliment each other I don't know if you have the ability to get a new desk at the moment but the colors don't match.
Edit: I assume the top of the desk can come off I recommend painting that black.
Edit#2: I recommend getting a headset stand like this one. AmoVee Acrylic Headphone Stand Gaming Headset Holder / Hanger, Extra Thick - Black https://www.amazon.com/dp/B00SGW9QLS/ref=cm_sw_r_cp_api_SZGKzbWFY1DH3

Love this one. Stylish, doesn't smudge too easily, and cheap.
