TP-Link UB400 Nano Bluetooth 4.0 USB Dongle Adapter for Computer, Laptop, Headphones, Speaker, Keyboard, Compatible with Windows 11, 10, 8, 8.1,7, XP, Black

Even works with home assistant

Needed a Bluetooth dongle for my PC so that I could connect my Sony Earbuds to the PC. Just plug it in and that's it.

Bought to add Bluetooth 4.0 support to a 2009 MacBook Pro (built-in Bluetooth is 2.1+EDR) running OSX Sierra (10.11.6), to use a Microsoft Mobile Mouse 3600 which requires Bluetooth 4.0. As other reviewers have said, it is plug-and-play - I was able to immediately pair the mouse, and the cursor movement was smooth. I had a couple of times where the cursor movement became jumpy; disabling the built-in Bluetooth with this command in Terminal and then rebooting fixes that issue: sudo nvram bluetoothHostControllerSwitchBehavior=always

This improved my laptop blue tooth/wifi speed

Works out the box on Kubuntu 20.04 LTS. Just plug it in and it works. A couple of weeks ago I bought my first pair of wireless ear buds and had a bluetooth dongle from about 10 years ago, that kept dropping the signal and walking across the room the signal would drop. Haven't had one dropped signal with the TP link and surprisingly I can walk into other rooms and upstairs and still have a signal.

There seem to be a lot of false claims about this adapter. Namely, that it works as an adapter with the PS4 It doesn't. Do Not Buy if you want to use with the PS4.

I have a Windows10 PC with which I have been using a pair of cable-connected budget speakers as I have never used the PC as a serious music, film or gaming platform. Having recently acquired a new Bose speaker for everyday use I found myself with a relatively old (6-7 years) Bose Soundlink Mini II without a role in its life. What to do? I bought this TP-Link UB400 to Bluetooth-enable the PC. It’s brilliant. Spectacularly easy to set up. Music in minutes!

Finally, a Bluetooth dongle that works with Ubuntu.

Ordered several of these over the past years. They’re are some of the few Bluetooth dongles that work great on older Apple Macs (Mac OSX 10.4 / 10.5 etc.). The other brands or the BT 5.0 version aren’t recognized by the system but this one works flawless for headsets , keyboards etc.

Dual Band connectivity with plug-in compatibility with Windows 11

日本メーカーの Bluetooth 5.4 のアダプターでは接続が非常に不安定でしたが、この TP-Link のアダプターは今のところ問題なく使えています。 キーボードやマウスを接続する場合、Bluetooth 4.0 で十分だし、Qualcomm 製チップセットを搭載しているところが決め手でした。 あと、地味ですが、アダプターに Bluetooth のロゴが刻印されているのもよいです。他の2.4GHz アダプターとの区別がつくので。

Działa całkiem ok

It's as easy as ramming it in a USB port and all Bluetooth functionality unlocks for you to use immediately. Windows 10 acts like you have Bluetooth built in and you can start syncing with your devices straight away. The range was much better than expected and speed is just as good, if not better than my laptop's Bluetooth. Highly recommend to anybody running Windows 10. It should work with Windows 8 & Windows 8.1 too, but I've only tested on Windows 10. Many people have trouble with other Bluetooth adapters not working and most recommend this TP-Link BT 4.0. Compatible with the latest standards of Bluetooth and backwards compatible with all previous versions so you can use any Bluetooth device to it's maximum potential with minimal energy consumption.
