But let's back up for a minute. The Moto Z (left) and Moto Z Force are Motorola's newest pair of flagships. They have a 5.5-inch display, a Snapdragon 820 processor, and run Android Marshmallow.
On the back of the devices are an array of pins that you can use to help magnetically snap on modules, or swappable components.
Like this one! It's a Kate Spade-branded external battery pack built by Incipio.
And this pico projector add-on that latches onto the devices to beam the contents of your phone onto any surface, such as a wall or ceiling.
There's also this JBL speaker that pumps out impressively loud audio -- essential for pool parties and BBQs. And it has a kickstand!
Not every item magnetically attracted to the phone's backing is a high-powered Mod. There are also a ton of slim cases in finishes and styles that cater to your self-expression.
Some are simple plastic. Others evoke leather and wood.
Collect them all!
You don't need these aftermarket covers to use the phones, either. But they do add a little something and are fun to snap on.
Taking them off isn't hard. But they're connected with four strong internal magnets, so you'll need to find a grip or slide a nail into a seam and gently pull.
Both phones are splash-resistant, and the magnetic attachments are made of gold to cut down on corrosion.
After you connect a Mod for the first time, you'll hear a chime and see some sort of message to confirm that the Mod and phone have synced.
Another look at the pico projector Moto Mod.
I snapped it onto the gold phone so you can really see its contours while you're using it. Luckily, you can quickly pull it off when you're done without turning off the phone.
A pretty loud speaker sits on the right side of this projector Mod.
JBL is one early supporter of Motorola's Moto Mod ecosystem, which gives this add-on an extra advantage.
But it won't be long before Motorola pulls in other third-party partners to expand its snappy offerings for the Motorola Moto Z and Z Force.
Here's a concept mod that projects the screen of the phone on a surface and lets you tap on the projected icons to interact with the phone.
Another concept mod, which shows that you can have another screen attached to the Moto Z and Moto Z Force.
In the US, the two phones sell exclusively through Verizon (hence that Droid Edition branding on the camera), but an unlocked version of the Moto Z is slated to come to the US and the rest of the world as well around the fall.
