Thanks Starr.C,
I did review Resolve Wi-Fi and Bluetooth issues caused by wireless interference before and moved the speakers around, turned one at a time, used just the keyboard, used just the mouse, deleted the bluetooth device from my phone and still the problem of interference happen when I connect the JBL Flip 5 speakers with my MacBook Pro (Retina, 15-inch, Mid 2015). They work perfectly connected to the bluetooth, but when I connect my bluetooth Apple Mouse or Keyboard it cuts out and in. If I just use either one alone it cuts in and out as well. I have Contacted JBL tech support and they said to contact Apple Support. I read that another person was having the problem with her Apple Magic Mouse and she had no replies.
PLESE HELP
