When connecting a 3.5mm headphone jack to iPad, it doesn’t go in completely. It gives the impression that the jack needs to be pushed more. This doesn’t happen with the same jack on an iPhone, iPod or another MP3 player.
You wouldn’t expect a goofy mistake like this from Apple, a company that has a world-class reputation of high quality products. In fact at the beginning me and my friends thought of it as a weird feature that needs to be figured out! But a feature or not it gives the wrong feedback.
The solution is obvious: make more space in the socket so that the jack can go it entirely and the user doesn’t keep pushing it in thinking there’s something wrong with themselves or the jack.
