What kind of material is used for the microphone membrane? And how is it fixed on the microphone? Due to what water does not get there?
I’m not sure on the material, but from what i remember from the design announcement, water does get in, but it is an enclosed unit so water doesn’t go into the rest of the device. When you finish a workout, swim or water sport, you simply select the menu option to eject the water. That causes the microphone to vibrate at a very high speed, which ejects the water in the slot.
