After I was back and forth with a few different mounts I finally took the leap and bought these as they are small enough but mighty. The mount is wide enough to not have to squeeze on my beat headphones and they rest on the silicone area. The best part is they come with 3M strips so if I want to relocate them I can buy replacement strips to remove and move them elsewhere without compromising quality regarding adhesion. Damage free and easy to use. Totally worth the buy to me!

Smooth, light weight but sturdy plastic, not metal. Removable without residue.

Ordered the deluxe metal version, received plastic version. Kept. It is a nice product. Smooth, shiny white plastic. Comes with 4 Brand Name Command strips for mounting, an instruction booklet. Fits my padded gaming headphones.

Love it

Style: Studio-Grade White – One Pack

I absolutely love this mount. It was incredibly easy to set up, and it feels very secure. It keeps my headphones within reach without cluttering my desk, and I love that it doesn’t damage the furniture. Highly recommend for anyone looking to clean up their setup!
