AirPods Pro are wireless Bluetoothin-ear headphones designed by Apple, initially introduced on October 30, 2019.[5][6] They are Apple's mid-range wireless headphones, available alongside the base-level AirPods and the highest-end AirPods Max.
The first-generation AirPods Pro use the H1 chip, also found in the second-generation base-level AirPods. Notable additions include active noise cancellation, transparency mode, automated frequency profile adjustment, IPX4 water resistance, a charging case supporting wireless charging, and interchangeable silicone ear tips.[7]
In September 2022, Apple announced the second-generation AirPods Pro. The newer iteration incorporates the H2 chip, Bluetooth 5.3 connectivity, improved sound quality and noise cancellation capabilities, an extended battery life, volume adjusting gestures, support Find My tracking, provide compatibility with Apple Watch chargers, and extra-small sized ear tips. A revision in 2023 added IP54 dust resistance, support for lossless audio in conjunction with the Apple Vision Pro, and a USB-C charging case.
Models
First generation
Apple announced AirPods Pro on October 28, 2019, and released them two days later on October 30, 2019.[7] They include features of standard AirPods, such as a microphone. They also have noise cancellation to reduce exterior sounds background noise, accelerometers and optical sensors that can detect presses on the stem and in-ear placement, and automatic pausing when they are taken out of the ears. Control by tapping is replaced by pressing a force sensor on the stems.[8] They are rated IPX4 for water resistance.[2]
The AirPods Pro use the H1 chip also found in the second and third-generation AirPods, that supports hands-free "Hey Siri". They have active noise cancellation, accomplished by microphones detecting outside sound and speakers producing precisely opposite "anti-noise". Active noise cancellation can be turned off or switched to "transparency mode" that helps users hear surroundings. Noise cancellation modes can also be switched in iOS or by pinching the stems of the AirPods using the force sensor.[9]
Battery life is rated to be equal to the second-generation AirPods at five hours, but noise cancellation or transparency mode reduce it to 4.5 hours due to the extra processing.[11] The charging case advertises the same 24 hours of total listening time as the standard AirPods case. It also features Qi standard wireless charging compatibility.[11] In October 2021, Apple updated the bundled charging case with MagSafe.[12] Like AirPods, AirPods Pro have received criticism for their battery life.[13]
AirPods Pro Gen 1s in their charging case
AirPods Pro come with three sizes of silicone tips, including the attached medium set. There is a software test in iOS called the Ear Tip Fit Test that "checks the fit of your AirPods ear tips to determine which size provides the best seal and acoustic performance" to ensure a correct fit, as well as a feature called "Adaptive EQ" which automatically adjusts the frequency contour, claimed to better match the wearer's ear shape.[7] Starting in early 2020, Apple started selling tip replacements for AirPods Pro on their website.[14]

iOS 14 also added the ability to apply headphone accommodations to transparency mode, allowing the AirPods Pro to act as rudimentary hearing aids.[19] In October 2021, a new Conversation Boost mode was added as a customization of the regular Transparency mode. It boosts voices above background noise and music.[20]
Second generation
The second-generation AirPods Pro were announced at an Apple media event on September 7, 2022, and were released on September 23, 2022. They use an updated H2 chip with Bluetooth 5.3 connectivity, and feature improved sound quality and noise cancellation, and longer battery life. They also include extra-small sized ear tips, and AirPods support swiping up and down to adjust volume. Ear tips are physically compatible with first generation AirPods Pro as they use the same connector, but Apple notes the second generation ear tips use a less dense mesh and recommends against intermixing them for acoustical consistency.[21][22]
The charging case includes the Apple U1 chip that supports Find My tracking, and includes a speaker for locating and status updates. In addition to Lightning, Qi and MagSafe chargers, it is also compatible with Apple Watch chargers. A lanyard loop was also added to the side of the case.[23][24]
In September 2023, Apple updated the second-generation AirPods Pro with improved IP54 dust resistance, an updated H2 chip that supports the 5 GHz band for lossless audio with the Apple Vision Pro, and a charging case with a USB-C port instead of a Lightning port.[25][26]
iOS 17 added "Adaptive Audio," which dynamically blends Transparency and Active Noise Cancellation to tailor the noise control experience as a user moves between changing environments; "Press" to answer/mute/end a call; "Personalized volume" which uses machine learning to adjust volume based on user preferences over time and surroundings; "Conversation awareness" which automatically lowers the volume if the user starts talking to someone nearby.[27] In iOS 18, a user can nod or shake their head to respond when talking to Siri and Voice Isolation during phone calls was also introduced.[28] In September 2024, the United States Food and Drug Administration authorized the use of hearing aid software by Apple in the AirPods Pro.[29]
Compatibility
Support for AirPods Pro was added in iOS 13.2, watchOS 6.1, tvOS 13.2, and macOS Catalina 10.15.1.[11][9] They are compatible with any device that supports Bluetooth, including Windows and Android devices, although certain features such as automatic switching between devices and single-AirPod listening[30] are only available on Apple devices using its iCloud service.
Comparative technical specifications of all AirPods models
Devices that support Bluetooth, including Android and Windows devices, although certain features such as Siri require an Apple device running iOS 15.1 or later, iPadOS 15.1 or later, macOS Monterey 12.0 or later, and watchOS 8.1 or later.[39]
