1st generation Apple announced the first generation of AirPods on September 7, 2016, at an
Apple Special Event alongside the
iPhone 7 and Apple Watch Series 2. Apple originally planned to release the AirPods in late October, but delayed the release date. On December 13, 2016, Apple began taking online orders for AirPods. They were available at
Apple Stores, Apple Authorized Resellers, and select carriers on December 20, 2016. AirPods contain a proprietary
Apple W1 SoC processor which helps optimize battery use as well as the Bluetooth 4.2 and audio connections. The advanced connectivity functions of the W1 requires devices running
iOS 10,
macOS Sierra,
watchOS 3, or later. They can also function as standard
Bluetooth headphones when connected to any device that supports
Bluetooth 4.0 or higher, including
Windows laptops and
Android devices. There are two microphones inside each AirPod, one facing outward at ear level and another at the bottom of the stem. Each AirPod weighs , and its charging case weighs . The AirPods are capable of holding a charge of around five hours. Charging them for fifteen minutes in the case gives three hours of listening time. During a complete dismantling, each AirPod was found to contain a 93 milliwatt hour battery in its stem, while the charging case contains a 1.52 watt hour or 398 mAh at 3.81 V battery. The model numbers for the first-generation AirPods are A1523 and A1722. Production of the first-generation AirPods was discontinued on March 20, 2019, after the second generation was released.
2nd generation Apple announced the second-generation AirPods on March 20, 2019. They are the same design as the first generation, but have updated features. Second-generation AirPods can be purchased with the same charging case as the first generation, or in a higher-end configuration that comes bundled with the
Wireless Charging Case, which can be used with
Qi chargers. The Wireless Charging Case can be purchased separately and is compatible with first-generation AirPods. It moves the charging indicator LED to the exterior of the case. The Wireless Charging Case was initially announced in September 2017 alongside the
AirPower charging mat, but was delayed by
AirPower's protracted development and eventual cancellation. The second generation AirPods remained on sale with a price cut following the release of the third generation in October 2021, but only available with the
Lightning charging case. The model numbers for the second-generation AirPods are A2032 and A2031. Preorders of the third-generation AirPods began on October 18, 2021. The third-generation AirPods were released on October 26, 2021, and are priced at $179. In September 2022, Apple released a $169 variant with a charging case lacking
Qi and
MagSafe charging compatibility. The model numbers for the third-generation AirPods are A2565 and A2564.
4th generation Apple announced the AirPods 4 on September 9, 2024. Currently assembled in Vietnam, they feature redesigned earbud control and speakers, the H2 chip,
Bluetooth 5.3,
IP54 dust resistance, and a smaller charging case that supports
USB-C charging. A higher-end version features
active noise cancellation and a charging case with a speaker for
Find My tracking and compatibility with
Qi and
Apple Watch chargers. The charging case no longer has magnets to mount on
MagSafe chargers due to its smaller size.
iOS 26 added Live Translation with the active noise cancellation version when used with an iPhone that supports
Apple Intelligence (
Apple A17 chip or newer). == Technical specifications ==
