Hello! Today I just received a new, unactivated, unopened iPhone 17 Pro Max with 0 charge cycles and a SIM + eSIM card. While inspecting the phone and checking the build quality, I noticed that when I pressed on the back of the iPhone, I could hear air coming out of the top speaker. I then decided to test the water resistance by removing the SIM card tray, pressing it firmly to my lips, and blowing into it. I heard air coming out of the top speaker. Then I tried the opposite, sucking air in through the SIM tray, and it also came out, but with significant difficulty. I decided to test the air leakage on my iPhone 16 Pro, and there is no such issue when I inhale or exhale through the SIM tray. There is no leakage; it is completely sealed. I ask you to check if you have this issue with your iPhone 17 Pro/Max; it may be a feature due to the new large top speaker
