I have a brand new Betron Portable Speaker which has been in my cupboard for 5 years. It's still in it's original box and packaging. I had it as a spare, but never opened it.
I suspect you'd need to know how to update the Bluetooth version from Version 4.2+EDR to make it work? If you're au fait with doing this and are interested please contact me.
Thanks for looking.
