Sony Inzone H3 Wired Gaming Headset with 360 Spatial Sound with Headphone Mount

Knox Gear Headphone Hanger Mount with Built-In Cable Organizer

Featuring soft padded contact points, the Knox Gear Hanger Mount enables you to organize headphones underneath your desk efficiently without damaging the finish of your table. With its adjustable design, the clamp can accommodate most desks and tables with varying thicknesses. It fits snugly and can be moved around and easily repositioned.

360-Degree Swivel

Thanks to a rotating and fully adjustable headphone arm, this mount swings right under your desk to provide a discreet, non-intrusive storage option. It swings back out with one simple swipe for easy access.

Clutter-Free Cable Management

Thanks to the built-in cable loop, you can now store your headphones underneath your desk while running the cable through the loop. This means no more loose wires lying on your desk, helping you reduce clutter without having to use headset stands and take up limited space on the desktop.

Quick & Easy Setup: No Tools or Hardware

Unlike under-desk mounts which require a whole lot of effort to properly install, Knox Gear makes the installation process simple and painless. No tools, no hardware, and barely any effort is required.

Spring-Loaded: No Manual Tightening Needed

A spring-loaded C-clamp makes removing and repositioning the headphone mount effortless, with no manual tightening needed and zero issues with sticking, drilling, or instability of the holder. Soft pads on the top and bottom clamp protect your desk from scratches and won’t ruin the surface with sticky adhesives.

Great for Desks, Tables & Gaming Stations

Attach to your living room coffee table, desk, or any shelf. The clamp opens up to accommodate most desks and tables, forming a tight fit while remaining easy to remove and shift to different gaming stations around the home.
