Pretty much all new laptops have Bluetooth built-in. Not all new desktops do, though, nor do many older ones. There are adapters focused on connecting to control devices like keyboards and mice, and there are some dedicated to transmitting audio to headphones. The Plugable Micro is the most popular and most reliable, and it costs very little, so it's the right choice if all you're looking for is something to connect your controllers. It also works well with Sony's DualShock 4 controller, though you may need to do a little fine tuning to get that controller working perfectly with Windows.
Then there are the many options made specifically for certain sound-related activities. Avantree's Audikast is one of the few recent devices that still has a USB input; most of the USB audio hubs released today are only charged via USB. It can connect to two headphones at once and supports the AptX Low Latency codec, but not the HD version. Fiio's BTR3 is actually one of the better and more compact USB DACs available right now, thanks to its powerful chipset and versatile codec support. The Avantree Leaf works great with the Nintendo Switch and other gaming devices. And the MakerSpot is a very specific tool that adventurous robotics hobbyists may find useful.
Finally, there's an important note to make. When you plug a compact model like the Plugable into a USB port, make certain you're using one of your computers USB 2.0 ports. USB 3.0 actually runs into interference with Bluetooth and can significantly hamper the devices. If all you have is USB 3.0 ports, you'll want to grab a USB 2.0 cable (one that is specifically not rated for USB 3.0) in order to prevent this interference and have a lag-free experience.
