I think OP has this: Amazon Page
I like how this one is held on by tension instead of just the tape / glue other ones use. I'm considering buying one now.
Awesome station, actually pretty jelly. But besides that the only thing I would suggest is a headphone stand or hanger. Here's an example if you're interested
Not OP, but it looks like something like this. I think OP has the same Sennheiser branded one that I do, but unfortunately it looks like those were discontinued (can't find them on Amazon anymore at least, not sure about other stores). The one I linked should work find though.
Any guitar hanger from Amazon will do just fine.
In case you want something that attaches to the corner of your tabel have a look at the ATH HPH300
you can get those table clamp hangers (like this: https://www.amazon.com/dp/B005LDVQ04) or start going to town under the table (like this: https://www.amazon.com/gp/product/B00P31BMHG)
Not a stand, but I use Audio-Technica's HPH300 headphone hanger. Gets the job done and is actually pretty portable.
I use the Audio Technica AT-HPH300, love that it has padding http://www.amazon.com/Audio-Technica-AT-HPH300-Headphone-Hanger/dp/B005LDVQ04/ref=sr_1_1?ie=UTF8&qid=1450050083&sr=8-1&keywords=Audio+Technica+AT-HPH300
I've got one of these http://www.amazon.com/Technica-AT-HPH300-Headphone-Hanger-Import/dp/B005LDVQ04
Dunno if it would work for that thick a desk though. They do have the stick on kind that goes under the desk, that would work. http://www.amazon.com/dp/B00P31BMHG/ref=psdc_172541_t2_B005LDVQ04

I use one of the clip on styles. Takes up about a square inch on my desk.

I bought mine for $35 from Amazon and it took 2 weeks delivery from Japan. But now it seems you can pick one up on Amazon for $24 with Prime
