The headphone jack is missing from the latest versions of the iPad Pro. It’s gone. Dead. Worse yet, the headphones that come with the iPhone will not work either. Apple ditched Lightning for USB-C. Instead, Apple is selling a USB-C to 3.5mm dongle for $9.

The latest iPad Pro models follows the trend lines set by the iPhone. Just like on the iPhone, the Home Button is missing, and the headphone jack is gone. It’s a concession some users might find surprising. On the iPhone, there’s obviously less real estate to integrate a large port but that’s, in theory, less of an issue in a large device like a tablet. But it makes sense. Apple tends to maximize margins by ensuring different products use a similar set of hardware. And since the iPhone hasn’t had a headphone port since 2016, it’s about time the trend hits Apple’s other mobile device.
