Most modern laptops have some sort of volume control buttons. Usually these are a set of Fn keys on the keyboard, but convertible laptops with screens that can flip around for use in tablet mode often have volume buttons on the side.
But adjusting audio volume with buttons can be a finnicky experience that requires multiple clicks to dial things in. The SoundSlide is a laptop accessory that takes away the need to click. It’s a capacitive touch controller that plugs into a USB Type-C port and lets you control the volume on any Windows, Mac, or Linux laptop by sliding your finger across the surface.
Available for $15 from eBay, Tindie, or Elecrow, the SoundSlide is also available from Amazon, but it costs $18 if you buy it there.
