Hi arnav whenever you open something that is waterproof you break the airtight seal and if you want to go diving or swiming with it you don't open it and I know this because I warn the customers the same thing when I am working at the clockshop. That as soon as I open up a waterproof watch to replace a battery they won't be able to go swimming or diving with it on. This goes same for the speakers because all waterproof things has a rubber gasket and if you get the wrong thickness and or size the seal will not work and may have no water resistance at all and when you put the original gasket back on you are guaranteed that it will be waterproof to rain, hail and snow but that's it. I say this because when you take a gasket off you stretch it just a little bit and therefore it looses the airtight seal sadly.
