Apple’s has two new iPhone 6 commercials featuring celebrity voice appearances by Justin Timberlake and Jimmy Fallon.

Timberlake and Fallon both manipulate their voices to be too-fast and too-slow as references to the camera’s high-speed and slow-mo capabilities.  

Each spot is 30 seconds long, and they’re embedded below:
