I've had my 6S Plus for a few days, and plugged headphones into it yesterday for the first time. I was surprised to feel there was no "click" when they were all the way in, like you get on any/most headphone jack. When you push it in, you feel the resistance before the final step that usually gives that feel, sometimes audible click. But that's just not happening here. You can tug the headphone plug out a little bit easier than on my iPhone 6 that gave a definitely click when pushed in. It just seems like the little angled metal that would usually lock into the tip isn't snapping down on to it. The headphones works fine, though turning the plug can produce a bit of static, also telling me the connection in there isn't THAT bad, but could be better. Does everyone else's give a good solid click when putting headphones in? I hate little stuff like this. I don't want to do an exchange over something like this, but it could get worse over time, and it is a little weird sometimes feeling like I don't know if I put the headphone plug in all the way. Thanks.
