Awesome Quality great for my headphones
Color: Walnut Wood
I recently purchased the Wood Headphone & Headset Wall Mount in Black, and it has truly transformed my workspace! The space-saving design is a game-changer, instantly decluttering my desk and giving it a sleek, organized look. The curved bearing area is a thoughtful touch, ensuring that my headphone head beam remains in perfect condition without any risk of deformation or dents. The combination of aluminum alloy and wood not only gives it a modern aesthetic but also makes it incredibly sturdy and strong. I was initially skeptical about using double-sided tape, but the 3M tape provided proved to be exceptionally reliable. The mount is securely adhered to my wall, and I can trust that it will never break or fall. What I love most is its versatility – it accommodates all types of headphones, even the heaviest ones, and I've even used it to hang my handbags and backpacks. It's truly a versatile and practical solution for anyone looking to optimize their workspace. I highly recommend the Wood Headphone & Headset Wall Mount for its durability, functionality, and the aesthetic upgrade it brings to any room!

I mounted it with a drawer pull
Color: Walnut Wood, Color: Walnut Wood
Functionality: 5 , Design : 5 , Price: 3 I was looking for a way to store my headphones and not clutter my desk. I also wanted to make sure the padding doesn’t get deformed by hanging them on a hook. This wall mounted option met all my requirements, even though I feel it’s a bit pricey for just a small piece of wood and metal. It’s nicely finished and the shape will minimize leaving a dent in the padding of the headphones. I was worried that the color wouldn’t match my desk but luckily it was very close. Based on other reviews I didn’t trust the adhesive. Instead of drilling a hole into my desk I thought I would try attaching it with one of the drawer pulls. The hole of the wall hanger was just a millimeter too small for the screw of the drawer pull, but a quick mod with my power drill and it fits perfectly. I’m glad I didn’t drill into my desk, and if the position ends up inconvenient I can easily swap it to a different drawer. I would highly recommend this product.
