This is the Moto Z's USB-C headphone jack adapter.
The Moto Z doesn't have a 3.5mm headphone jack. But this little doohickey will take care of that for you.
One of the biggest stories from the announcement of the Moto Z at Lenovo's TechWorld event in San Francisco back in June was that the phone does not have a 3.5mm headphone jack and instead relies on the USB-C port to pump out audio. Most folks are in two camps on this. That's either a nonstarter, or it's not a big deal at all.
And in reality it's sort of both. It doesn't have a headphone jack. But, Motorola is providing a USB-C adapter so that folks who prefer to listen to audio via a wired connection aren't left out in the cold.
Today, we're getting our first look at that adapter courtesy of the Moto Z Droid Edition and Moto Z Force Droid Edition on Verizon.
And guess what. It's a USB-C to 3.5mm adapter. There's really not much more to be said that that. You get about five inches of cable, with one end plugging in to the phone, and the other for your headphones. There's also a little rubber piece that (I think?) is for helping make sure they stay connected. It's one more thing (OK, two, I guess) to lose, sure. But it's also not a horrible compromise.
