How we chose
We compared manufacturer listings and specifications on Amazon as of November 2026. We did not test any of these adapters by hand, so every point below comes from what each listing says.
Our criteria were the operating systems each listing names, the Bluetooth version and backward compatibility claims, the number of devices each listing says can connect at once, driver requirements, and the limitations written into each listing. We also skipped size and dimension fields that did not look plausible for a USB dongle. For background on how port types and wireless versions relate, see USB-C, Wi-Fi and Bluetooth Versions Explained.

How to choose the best USB Bluetooth adapter
Start with your operating system. Several listings here name Windows 11, 10 and 8.1 as the only supported systems, and a few add Windows 7 or Linux. If a listing says macOS or Linux are not supported, treat that as a hard limit rather than a setting you can change.
Next, check the Bluetooth version and backward compatibility. Most listings here state a version, and many say they work with older devices. A newer version on the adapter does not upgrade an older headset, so confirm that your own devices fall within the compatibility the listing describes. For how versions and audio profiles relate, see our Bluetooth Audio Codecs and Profiles Explained guide. The Bluetooth SIG website covers the standards themselves.
Then look at device limits and conflict notes. Some listings say to disable built-in Bluetooth first, and some say only one Bluetooth audio device can be active at a time. If you rely on a 2.4G USB receiver or a Wi-Fi peripheral, read the compatibility notes closely, because the Avantree listing states it does not support those.
Consider drivers and setup. Some listings describe plug and play with no driver installation, while others need an internet connection or a manual download for older systems. Nano designs are described as staying in a port, which suits travel, but range figures apply only to the conditions the manufacturer states. If you connect a USB adapter alongside other devices, follow the manufacturer’s manual for safe use. For port types, see USB-C, Wi-Fi and Bluetooth Versions Explained.
What to look for
- The Windows versions the listing names, and whether Linux or macOS is excluded.
- The Bluetooth version and the backward compatibility claims.
- The listed number of devices that can connect at once.
- Driver requirements: plug and play, internet needed, or a manual download.
- Stated limits such as range, console or TV compatibility, and built-in Bluetooth conflicts.
FAQ
Do these adapters need a driver installed?
It depends on the listing. The UGREEN, Techkey and KAIY listings describe plug and play with no driver installation on supported Windows versions. The TP-Link listing requires an internet connection on Windows 8.1 through 11 and a downloaded driver for Windows 7. Cudy offers automatic driver setup on Windows 10 and 11, with manual drivers for other systems. Follow the manufacturer’s manual for setup.
Can I use one with a PlayStation, Xbox or TV?
Several listings say no. UGREEN says it cannot be used directly on PS3, PS4, PS5, Switch or Xbox consoles. Avantree and SUMEE list TVs and gaming consoles as unsupported, and KAIY says it does not support direct audio connection to TVs, car stereos or consoles. Check the listing before buying for a console or TV setup.
Will these work with a 2.4G keyboard or a Wi-Fi printer?
The Avantree listing states that it is not compatible with 2.4G or Wi-Fi devices. The other listings we compared do not mention support for 2.4G USB receivers or Wi-Fi peripherals, so check each listing against the devices you plan to use.
Should I turn off built-in Bluetooth first?
Amazon Basics and SUMEE both say to disable built-in Bluetooth before use or expect a conflict. Check your computer’s manual for how to turn its built-in Bluetooth off.
