Hello, I am facing the choice of the jbl charge 3 or flip 4 mobile speaker, I have this question for you, today I watched charge 3 in the neon and flip 4 unfortunately the charge was discharged so I did not test it. Why in charge 3, after pressing one of the side membranes, the other one as if it comes out, I know that this is an understandable problem that after pressing and holding the membrane, the second one comes out and after a second it returns to its original place, i.e. I press the second one is pushed out and returns, after pressing two at once you can hear that the air is escaping, it's not my rooms, because in flip 4 something like this does not occur and the membrane does not hide, is it normal that the charge 3 is not tight ???
