4 USB Bluetooth Adapter is a plain and simple way to get Bluetooth on a desktop or an older laptop that lacks built-in wireless. 4 standard, which gives you a stable connection with less interference and better power efficiency than older versions. You can pair wireless headphones, keyboards, mice, game controllers, and even transfer files between your computer and phone. It also supports audio input, so hands-free headsets work fine.
