1368148060279329-2085768816972321 Spatial audio with dynamic head tracking: Sound surrounds you. Immerse yourself in a three-dimensional experience every time you listen to music, watch a movie, or watch a TV show. The gyroscopes and accelerometers in AirPods track your head, so you feel like you’re right there in the middle of the stage. Adaptive EQ: Music automatically adapts to the shape of your ear. Inward-facing microphones detect what you’re listening to and adjust the low and mid frequencies so you hear every note clearly. Longer battery life: AirPods (3rd generation) have one hour more battery life than AirPods (2nd generation), so you can enjoy up to 6 hours of audio playback and up to 4 hours of talk time. A 5-minute charge gives you about an hour of audio playback or talk time. And with the Lightning Charging Case, you can enjoy up to 30 hours of audio playback. Water and sweat resistant: AirPods and the Lightning Charging Case have an IPX4 water resistance rating. That means you can use them in the rain and during intense workouts. Magic all the way around: All you have to do to use your AirPods is remove them from the case. They are designed to switch between Apple devices automatically and have a built-in detector that knows when you have them in and when you don't. If you turn on Announce Notifications, Siri will read them aloud to you when you use AirPods. And with Audio Sharing, you can pair two pairs of AirPods and watch a series or listen to a song with whoever you want. Refurbished AirPods / US Version / Only the charging case and stereos are original. The case, cable, and silicone tips are compatible with AirPods, not original APPLE.
