We told you they were coming: Apple officially unveiled its new “EarPods” earlier today. The company explained during this morning’s media event that the EarPods are three years in the making. Apple has yet to post the video of the full iPhone 5/iPod event, but now we get a look at a video played during the presentation. It features Jony Ive explaining the process of creating the new earbuds. In addition to the engineering process described by Ives above, Apple explained on its website that it tested over 100 prototypes to make the EarPods more durable and stable than its previous-generation earphones:

Apple engineers asked more than 600 people to test over 100 iterations of the Apple EarPods. Testers ran on treadmills in extreme heat and extreme cold. They performed various cardio workouts. They were even asked to shake their heads side to side, up and down. The result: Apple EarPods provide stronger protection from sweat and water, and they’re remarkably stable in the ear. Which means they stay in, even when you’re on the go.
