Bluetooth Earphones Issue - Both Connects under same name (no master-slave config..)

Hi,

I have Ubuntu mate 18.04 & recently I bought Haylou GT 1 Pro earbuds, which connects to mobile / laptop directly , each one connects with same name ,
So they are working fine with Android 9 mobile but not working in Ubuntu, I hear no sound and Bluetooth manager shows connected.
I have another earphone from same brand with Master-Slave configuration which is working.

dmesg :

[ 1313.700337] input: E8:EC:A3:1E:14:B0 as /devices/virtual/input/input26

bluetoothctl :

I have Samsung U-FLex

I have a similar issue in the sense that it does work well on everything else except Ubuntu-Mate install I have, i.e. I can hear sound, but can't record my own voice and people can't hear me (whatever the voice chat you can think of).

So, Mike doesn't work on Ubuntu.

If (for instance) I try Skype or messenger, their UI shows me that the UFlex is identified.... but voice sound doesn't get through.

I did search and dig for info... maybe the wrong places.

Replies / answers welcome

Thanks

p.s. Somewhere I read that Bluez would work vs Blueman. Real?

Here is what I get at my end:
