My first attempt, I was planning on following those instructions, but I could bare the cold temperature (its actually not as bad as I anticipated the cold to be. Barely worked, we got it connected then wouldn’t work. Range is impressive too, while the headphones claim they can connect over 30ft I have managed to get connected from over 40, more than enough to connect from another room or sometimes even floor. Très solide et très lourde. Before i was using speeds of 1333. I happen to be sprouting my second bass head into the world and wanted a waterproof (for water birth) headphones i didnt care about. ;). When you first go to put it on, you think "oh dear God this isnt going to fit" but it does. Im guessing this speaker was a return for battery issues and upon inspection it checks out. Hence, no sound from either side.
