Both earbuds have dual optical sensors that sense when they’re in your ears to pause and play music, and there are dual-voice accelerometers that can detect when you’re speaking. Each earbud for the AirPods are packed with two microphones, an antenna, a battery, and the W1 chip.
Since each earbud has all that tech, you can use one without the other — all audio will automatically be routed to the earbud you decide to use.
Once you pair the earbuds to your iPhone, it will automatically pair with your Apple Watch and Mac if they’re running the latest software — watchOS 3 and macOS Sierra.
The earbuds themselves will only have five hours of playback time per charge.
The AirPods don’t come with the iPhone 7, and they’re fairly expensive: $160.
