I've noticed this over the last 3/4 weeks (wow already a month!) of owning my 6 Plus. It seems that the headset jack doesn't give the same "click" like my other iPhones did (iPhone 4, 5, 5s). The click is more muffled and the connector seems to slip out easier. I have yet to pull the cable out accidentally yet, but it got me wondering if anyone else has a phone like this. FWIW, I'm not returning this phone for a refurb from Apple. It seems to have escaped every -gate problem and typical early production problem iPhones have had (yellow screens, too blue screens, ghosting, etc). A slightly loose headset jack is not enough to worry me and it if it worsens, I bought AppleCare so I got two years. I just simply want to know if this is normal for this iPhone or something exclusive to just a batch or two.
