USB Bluetooth headphones problem

Using Zorin 8, on ASUS mobo with Rosewell internal port adaptor (usb, sd, etc, all in one). Everything is working great, but...
Did following steps, bluetooth is able to connect and headphones work, but have to fiddle around with settings every time I want to use my BT headphones. (Jam Transit Bluetooth headphones)

Selected Iogear adaptor from Ubuntu Hardware Support list.
Plugged in usb adaptor.
Installed Blueman. Ran detection
Went to Bluetooth in Settings and detected headset, ok.
Device does not show up in Sound.

Searched through various Ubuntu forum help sections, finally found that running the command :

pulseaudio -k 

Then my BT headset appears in the BT devices list and the Sound as expected, BUT headset shows up as mono device when I click Test and no sound.
I dunno what does it, but randomly toggling between built-in audio devices then back to my Jam Transit BT headset then actuates my headset and violla! full stereo and it works! .....until I shut my PC down and have to type pulseaudio -k again and toggle around the sound devices once more.

Obviously Im doing something wrong, why wont Zorin keep my settings and properly recognize my headphone?

Thanks
