I ordered my AirPods on January 6. Once shipped, Apple said they'd get here on the 20th, then UPS said the 17th, then the 20th, then the 17th. They came in a tight little box, the size of which seems to be influenced more by the Lightning cable inside than the headphones and case.
Connecting AirPods to iPhone was a piece of cake. Pop the case open, hold it within a couple inches of iPhone, tap Connect, and you're done— until a few minutes later, when an iPhone Bluetooth glitch requires a restart. When first placed in your ear, they chime like a '90s PC dialog box. Switching to Mac, iPad, and Apple Watch without pairing is very nice.
Pop the case open near your iPhone at any time to see the battery charge of both the AirPods and case. Battery life is phenomenal.
Getting the double-tap right is taking a few more tries than I anticipated. Since it's about the only way to do anything (volume, answer, end calls), I'm sure I'll get the hang of it.
Siri is far more accurate when using AirPods. Pausing by taking a bud out is flipping amazing. They're comfortable—it's almost like they aren't there. You can safely jog with them. They sound good and crisp, definitely better than your usual earbuds.
"Almost magic" as a product tagline seemed over the top, goofy. But it's spot on.
