I have Onyx Studio 3 sometimes it play discontinous. No matter which device android or windows. It's saying its version is 3 - 5. Are there any firmware for it?
It`s happening when 2 devices are connected in the same time. For reproduce the sound of the device #1, stop the device #2.

How do you leave it plugged in and play music at the same time? because mine does not play when it's plugged in unless I unplug it.
I have one too and it works: try to plug it in to charge and, after that, press again the start button. See if the light goes on and if it does the sound it usually does when it's starting. If yes, it will work. Maybe you will need to reconnect the bluetooth.
