Creates a systray Bluetooth icon, in which you have some options.

USB SECURE DIGITAL ADAPTER DRIVER

CSR Harmony driver v2.1.63.0 very big (418 MB zip, exactly the same as on TP-Link UB400) but also includes useful (although probably completely unnecessary for basic use) functionality/options.

Range: 4 meters + 0,5 meters inside a bathroom.

CSR 4.0 (Cambridge Silicon Radio) (REV_8891) cheap half circle shaped USB BT adapter (USB2, BT version 4.0), photo : On one day of testing (out several), with only 50cm distance without interference, the connection completely disconnected several times, then returned to normal in a few seconds.

USB SECURE DIGITAL ADAPTER WINDOWS 10

The driver: this dongle has two operation modes, either 1) Windows 10 Generic Bluetooth Radio (no external driver needed), working within вЂњBluetooth & other devicesвЂќ or 2) CSR Harmony driver = (v2.1.63.0 dated 22 March 2012, still works somewhat alright) (doesnвЂ™t have the battery indicator whereas the generic driver does have that).

Range: 4 meters + 0,5 meters inside a bathroom.

If you donвЂ™t transmit anything over Bluetooth, the WiFi works somehow, but once you listen to music over Bluetooth, the ping either times out or is 100вЂ“2000ms.

The WiFi in this dongle is completely useless.

Range: 4 meters + 2 meters inside a bathroom (exactly the same as EDUP EP-AC1661 and MPOW BH456A).

XVZ Bluetooth+WiFi USB dongle (VID_0BDA&PID_C820 and REV0200): The WiFi part worked for 2.4GHz but not at all for 5.8GHz (or almost never worked).

Range: 4 meters + 2 meters inside a bathroom (exactly the same as EDUP EP-AC1661).

MPOW BH456A Bluetooth 5.0 USB (VID_0BDA&PID_8771 and REV_0200): Realtek Bluetooth 5.0.

Range: 4 meters + many meters inside a bathroom, does not cut sound at all! Superb range compared to USB dongles!.

For comparison, iPhone 11 Pro: sound does not cut at all.

All the USB dongles operated using the SBC codec.Д¬OMPATIBLE, audio doesn't seem to cut/drop:

My test setup had the dongle 4 meters away from bathroom and I walked into the bathroom with headphones, closing the door. Compatible and non-compatible USB Bluetooth Dongles (Windows + Sony WH-1000XM3 and WH-1000XM4 compatibility). This is a bit complicated and long, but anyway, here goes. Eventually I found out that I need to disconnect all connected BT devices and then I was able to disable. At first I thought there are significant differences between those computers, but at the end I just had a problem with my MacBook, where I could not disable the onboard 'Bluetooth Radio', which prevented installing most USB BT dongles.

USB SECURE DIGITAL ADAPTER PRO

I tested with a desktop PC and MacBook Pro 16' (2019). I did not have time to test everything, but at least I'm not finding any sound quality problems/differences other than sound cutting. There are two main problems: 1) some dongles have audio dropping/cutting problem (audio pops randomly), 2) all A2DP dongles have a very, very limited range (few meters or less with obstacles).Дifferences between SBC, AAC, LDAC, aptX, aptX HD? There probably are differences, but so far I have not been able to hear any difference between those, nor have I been able to detect latency differences. It seems for example Avantree Leaf might have a greater range, but I need the controls so those won't work for me.ДЄ good A2DP (then one with the controls supported) adapter does not exist, or if it does, I haven't found it. I have not tested the audio transmitter type adapters (audio class device), which do not support 'multimedia' controls (play/pause, volume etc.). For some reason a phone can manage a fairly reasonable connection to the headphones, much greater distance or obstacle immunity than any dongle can do. It has become clear to me that at least on Windows, the A2DP Bluetooth technology for headphones is not doing very well.

I have now tested numerous USB Bluetooth dongles in order to find a reasonable, working dongle to be used with WH-1000XM4 with Windows 10.
