I selected a nice headset holder designed by rAthus, the Simple Headset Holder (20mm to 70mm), due to its appealing design and alignment with my requirements. Nonetheless, I found it necessary to modify it to suit my specific needs. I opted to mount it beneath the shelf using double-sided tape, prompting me to eliminate the screw holes and integrate a horizontal plate instead.
