I personally feel 'cord getting caught
is the real motivation behind killing the jack. Every time I've dropped my iPhones since the first one came out, it was because the headphone cable got caught on something and yanked the phone out of my hand or pocket. I am unwilling to use bluetooth as the signal cuts out, batteries are always dead and occasional pairing difficulties. When my iPhone SE dies...(my 9th iPhone) I will likely have to switch to an Android.
