A single cable means that a user no longer must deal with two extra batteries to keep charged and two bluetooth devices to keep paired.
I have been on calls with people where their audio cuts out midway through due to charge or connection issues. Those issues are impossible and rare, respectively, with a jack based mic/headphone.
I have seen and heard of people dropping one of their buds on the street, in the sink, or into a vat of liquid nitrogen... Not something that happens with a jack.
Don't get me started on the cost. In many cases you pay 5-10 times as much for wireless buds at the same level of audio/call quality.
TL;DR bluetooth is shit, batteries are shit, tiny expensive easy to drop/misplace devices are shit.
