Funny Points:
(1) The wireless speaker is so tiny, easy to take:39*37.5Mm size, much smaller than your hand 120g weight, much lighter than mobile phoneChic and cute color as a decoration, it's not a bad choice if you put it at your bag, bike etc
(2) Interesting mixed choice:
How to do if you want to use 1 pc black and 1pc red color speaker at the same time?
It doesn't matter. You could chose 1 black color and 1 red color speaker, connect them through interconnection function.Also, you could use one by one alone.
How funny it is!
