Review on Techkey USB Bluetooth 4.0 Adapter Dongle: Enhanced Connectivity for PC Laptop Desktop, Stereo Music, Skype Calls, Keyboard, Mouse | Windows 10 8.1 8 7 XP Vista Compatible by Tyler Markham

Great! We have a very nice old HP laptop from before bluetooth was everywhere. Windows 10 crashed it on install years ago, so HP has been happy to use Ubuntu ever since. We now have Ubuntu Studio version 19.10. We plugged in the dongle, typed "blue" into the software search, and listed "Bluetooth adapter" and "Bluetooth manager." The first adapter is simply installed with the Ubuntu machine name. Just use the Bluetooth manager to set up the dongle and you're good to go. Excellent! Remember that your Bluetooth headphones only have a limited number of slots available. So if you're trying to connect dual jack headphones that are already paired with your Android phone and Android tablet, for example, you'll need to unplug or disconnect your headphones from other devices. (But that's not the fault of this key. In fact, the simple installation made it easy to find our mistake!)
