The Kubuni is a headphone stand that does more than display and store your headphones. It lets you plug in over-the-ear wired headphones and connect them to other devices via Bluetooth. You can switch between inputs via its knob. It also has a volume control.
Crowdfunded projects pose a degree of risk for buyers, so be sure to do your research and fully read the seller's detailed description and production plans before plunking down your hard-earned money.
