I just got my second set. I haven’t done any of the set up stuff yet. I wanted to make sure this set wasn’t going to die, too before investing any work into setup. The number one reason I wanted these was for the music sync. As you can see, it’s fantastic. I really put it to the test. Here’s my original review that was never approved- I would have been less aggravated if they just hadn’t worked at all. But they did work. And worked well, synced with the music perfectly. I was so excited. Then it stopped completely. DEAD. I’ve tried everything. I disconnected everything and started over. Tried a different outlet. Nothing. Dead. I never made it to pairing with the app or even took the remote out of the package. I just plugged it in and turned it on. It was like a Rave in here for a minute. Then it went away. Grrrrr.
