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.

Asked by: Star1412
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.

Asked by: christian

Hi, I just bought a HK Onyx Studio 3. Inside the box there was a Quick Guide brochure, a Safety paper and Warranty but no full manual/guide. How can I get a full Manual?, because I can not find it in this web, I just can see a spec sheet.
