That's the ZTE Axon in the middle, but one of these phones is an Axon Pro. You'd be hard pressed to tell the difference without running tests: the phones share much of the same hardware. The phone's 5.5-inch display is coated in Corning Gorilla Glass 3, and has a 1080p display.
The solid metal body feels nice and sturdy, and it's available in three colors: silver (shown here), gold and dark blue. And see those cameras? One is a 13-megapixel shooter, the other is a complementary 2-megapixel camera that helps the phone capture a wider depth of field.
The headphone jack sits up top. The phone has a pair of audio chips that work together to pump out high-quality hi-fi audio. You'll only hear the souped-up audio if you're playing music through headphones, but it sounds rather nice in our tests.
