Magnet and double sided tape
Style: Base Station Mount + Headphone Hanger
Double sided tape on a metal plate with the magnet works perfect for a non metal desk.

Better off leaving it on your desk cause your headset will end up on the floor

Don't wait, buy it!
Style: Base Station Mount + Headphone Hanger
I was hesitant to purchase this product, but I am glad I did. My SteelSeries Wireless Nova Pro fits perfectly into this and it looks clean being added to my desk set up. The build quality is great! I bought on for my wife's headset and I think my son will want one now.

it’s really small in depth
Very difficult to open and watch your finger so you don’t pinch them. Great idea. But too short and length or width so I have to send it back.
