A2 Black worked great for 2 years ... now it needs to be set up every time I use it AND if I change music (album) it needs a new setup. PURPLE light flashes constantly. When it is OFF dim red light it will daily at some point start flashing yellow. I like it when it works HOWEVER think it is time to change BRANDS ... BLUETOOTH would be so very much easier.
