How to get Bluetooth 5 on an older Galago Pro with BT 4.2?

[mahesh]

Hello all,

I've been trying a few Bluetooth headphones and headsets for work (for Sjype/Meet/Zoom conference calls) but my coworkers all say the quality is always worse than my cheap wired headset. I've tried a very high quality BT 5 True Wireless headphone (Jabra Active Elite 75t) and a boom mic headset (AfterShokz OpenComm). After lots of testing, I realize the problem might be due to the older Bluetooth 4.2 version on our 2017 Galago Pro laptop. The call quality is perfect on my Google Pixel 3 XL which has BT 5.

I checked around for a Bluetooth 5.0 USB dongle but it seems compatibility with Linux is very limited.

Would anyone have a suggestion on how I could possibly get Bluetooth 5 solidly working on my older Galago Pro? Thanks in advance for any tip(s).
