*Edit: Brief summary of my questions 1) how do I get a successful connection, 15mins of trying have driven me crazy, and 2) why are there three separate devices being listed? So obviously my main concern is part 1, but even if I solve that (edit I solved that) I still wonder what and why there are three different devices being shown?
I'm trying to pair my earbuds with ubuntu running gnome, and I spotted something unusual that hasn't happened before when trying to pair bluetooth audio (my old original ear pods only showed one device).

Basically, there are three devices being listed in the Settings->Bluetooh dialog for my buds, and so far (despite one of these saying successful, a few seconds later it changed to disconnected)(2). To make things more confusing, there are multiple ways to pair the audio device, including putting the buds back in the case, closing the case, waiting 6 seconds, then simply opening the case lid again to initiate pairing mode whilst buds remain in the case. Another method is to tap and hold the touchpads of both buds for 10 seconds to initiate pairing.
The method I have always used it just to put the things in my ears, open Galaxy Wearable on my smartphone and click yes to the 6-digit number - as long as I'm nowhere near anyone else, its going to be my code. But of course, that's probably using the Samsung-to-Samsung protocol, SmartThings? I think its called, which works even when bluetooth is turned off on the smartphone. It's a little different when the broadcast device is not a Samsung, but I haven't had such trouble on a PC (or Manjaro laptop).
The guides I have found on google are either so littered with ads that they grind chrome to a crawling death; the reason I'm running the OS I am was because I want to extend the life of my two aging laptops ** outside of the home I've been (forced) using *nix since the 90s for work purposes when solutions required it, etc. But as you see from my laptop specs, I finally went 100% Linux to prolong their life and I'm now a 100% Linux convert, I'll never go back to another OS, regardless of spec!)
Any suggestions?
GNOME Shell 3.38.4, Kernel 5.15.0.56-generic, OS 20.04.01ubuntu, x86_64

My laptops are:
- Packard Bell TE69KB, 8Gb RAM, but only 1the.4Gz AMD A4-5000 cpu, running ubuntu based OS with Gnome desktop
- Lenovo s21e-20, N2840 Celeron @ 2.16Ghz, 2Gb RAM with a mere 32Gb flash drive - oh how fast that loads up! If only the capacity was bigger! This is running Manjaro which is blindingly fast compared to almost all the other distros I tried
Even my home PC which is only a couple years old, whilst it still dual boots Windows, I'm primarily booting Linux. Windows exists for Visual Studio. Thats it. Come on Microsoft, make that port! You know you want to! VS Code is awesome, but Visual Studio it's not!
