    This device is exactly what it says it is: a Bluetooth 5.0 USB nano-dongle. It will work under Windows with the Techkey Driver Package, and despite not being officially supported, will also work under Linux with a modern kernel (5.8.2 or later) & some tweaking.The device is essentially a rebranded ASUS USB-BT500 bluetooth dongle. It works reasonably well – i get better range and performance out of it then any other Bluetooth 4.0 nano-dongle I own. The connection is more reliable, stable, and drops out less. It’s not perfect – the range is about average, and it still has some connection issues from time to time. For $20, it’s not a terrible deal if you’re looking for a Bluetooth 5 receiver.So, about those drivers.Many reviewers have pointed out that Windows 10 doesn’t require a driver for bluetooth devices. This is correct.However…This dongle along with its cousin, the BT500, uses an RTL8761b chip. The RTL8761b chip, like many other modern devices, rely on the operating system to push firmware to the device. (essentially the code that runs inside the device, which tells it how to operate). The firmware is not provided as of yet to Microsoft or the linux-firmware package. Therefore, Windows requires an external driver to push the firmware to the device.Thanks to Meghan in one of the other review comment threads, we know that the Techkey drivers are virtually identical to the BT-500 drivers. These drivers are properly signed by Realtek, so you can be reasonably certain that the drivers are safe to use.This is the same reason that the dongle is not ‘supported’ under MacOS or Linux. It is possible to get the device working on Linux by installing the firmware manually. (essentially, taking the ‘rtl8761b_mp_chip_bt40_fm_asic_rom_patch_new.dll’ from the drivers and installing it in /lib/firmware with a proper name & copying the config from the rtl8761a. use ‘dmesg’ when you connect the device for more information.)It is unlikely that this device will ever work under MacOS unless there’s a way to load custom bluetooth firmware.This will, hopefully solve any confusion with this dongle. We can only hope that Realtek will release the firmware to the OS providers, so that this device will work without drivers on Windows and Linux.Read more

    Judging by the frustration from other people here, I’m guessing it was because they didn’t have a cd reader. I have an external cd drive since I do have music CDs and other disks still. But I tried using this without installing drivers and it wouldn’t find my Powerbeats Pros. It found my Amazon echos though. Not sure why.Regardless, after driver installation, it worked fine. Sound is good, and connectivity is what you’d expect. There aren’t too many bluetooth 5.0 adapters that aren’t actually sound cards or whatnot, so there isn’t too much competition here.The packaging and polish of this thing is unremarkable. You can tell they spent like a percentage in the single digits of their budget on packaging and presentation. They really should have made the driver available by download.So yes, you really do need a way to install driver from the disk.One might wonder why this is still USB2.0 when the world has already moved on to bigger and better things.Well… bluetooth transfer speeds are well below even the maximum USB2.0, so I guess this makes sense..Read more

    This dongle allowed my 6 year old Dell laptop computer, which never would connect with my hearing aids, to connect. It also allows more than one device to be paired with it so you can switch from one to another, such as to a speaker, then a phone or then to your hearing aids. I am more than satisfied. The brochure even explains that the Bluetooth that comes with the Windows operating system is a bare bones Bluetooth. The only difficulty will be for those that cannot find the Device Manager file on their computer. Just type Device Manager in your task bar search bar. It will show you it is in the Control Panel. Click on it and uninstall all the Bluetooth settings. Then run the enclosed disc after you have plug in the Bluetooth dongle and follow the instructions.Read more

    This works for my needs, so no complaints there.The range is a bit less than the range I can get from my phone, but my primary use for this is while I’m sitting at my desk anyway.Strangely, the drivers are shipped on a micro-cd, so if you don’t have a DVD/CD player in your computer, you will have a difficult time installing the drivers. It would be nice if they would make them available on a web site.It seems to be a Realtek rtl8761 chip, so you might be able to find drivers from Realtek directly.Read more

    It is small and discrete but works flawlessly.I had recently purchased a pair of Bluetooth over-ear headphones and paired them with my desktop. But, for some reason, my computer lost Bluetooth functionality and I was not able to restore it. My other option was to buy a Bluetooth adapter and I decided on this one.As soon as I received it I plugged it in and installed the driver provided on a mini-CD. Even though the install requires a computer restart, I was able to pair my headphones without any issues. I am now listening to music cable-free and it sounds great!If my experience changes in the near future after I have a chance to use it for a while, I will update my review with my new impressions.Read more

    Simply the best bluetooth 5.0 adapter on the market. It’s tiny and works flawlessly with windows 10, logitech mx3 and apple airpods. Better yet, I noticed it’s actually bluetooth 5.1(see picture) even they only advertise it as 5.0. Great deal!Read more

    During this social distancing situation, I needed a way to connect my beats-x and my Samsung buds to my desktop PC so I can talk during the online meetings. I like that this Adapter because it is the latest Bluetooth module and it is backward compatible additionally it has a very small profile.Read more
