I don't see why people are hung up on this. Imagine even just 2 or 3 of the same model "JBL SpeakerName" nearby, how would you know whos is whos? Renaming is common.
You would know which one is the desired one because only the desired one would be in pairing mode at that moment. Obviously a collision (if I can say that word) is possible, but unlikely enough for most purposes.
