Recently, Apple announced an update in 2023 WWDC, bringing Adaptive Audio (“adaptive” function) to AirPods Pro 2. According to the environmental conditions of the user, it dynamically combines “active noise cancellation” and “transparency mode” and automatically adjusts , so that the majority of AirPods Pro 2 users can have a better experience. After the update, AirPods Pro 2 will use machine learning (Machine Learning) to control the playback volume and noise reduction of the headset when the user speaks, and then enhance the sound in front of the user, so that the user can communicate with other people without lowering the headset.
Although the Adaptive Audio function has not yet been officially launched, if you have AirPods Pro 2 and a MacOS device that can install xCode, and your iPhone has been upgraded to iOS 17 Developer Beta, you can follow the steps below to try the Adaptive Audio function first . Friends who are interested in trying the iOS 17 Developer Beta version but have not yet upgraded can refer to my previous teaching (link:
The editor has actually measured that after the “adaptive” function is turned on, the noise reduction ability will be lower, and the system will automatically adjust. This function seems to be temporarily sensitive to human voices. I and my colleagues have tested that when someone is talking next to me, the noise reduction function of AirPods Pro will drop. In addition, the editor tried to use speakers to play the voice of people speaking, simulating broadcasts in airports, train stations and other places. The editor found that after enabling the adaptive function, the user can still hear the broadcast clearly through the AirPods Pro.
In addition to the “Adaptive” function, this update also added the “Dialogue Awareness” function. Regardless of whether the user uses noise reduction or adaptation mode, if the “dialogue perception” function is turned on, the microphone of the AirPods Pro will sense whether the user is talking. If it senses that the user is talking, AirPods Pro will immediately switch to transparent mode, which is convenient for the user to talk face-to-face with other people. After the user stops talking for about 5 seconds, AirPods Pro will automatically switch back to the noise reduction mode selected by the user.
The editor first played music in the background, and then enabled the “adaptive” and “dialogue-aware” functions.
▲Music playing in the background, “adaptability” on, “dialogue perception” on
Then the editor talked with colleagues around me, and it can be seen that the system automatically switches to “transparent mode”.
▲Music playing in the background, “transparency mode” on, “dialogue awareness” on
After the editor stopped talking for about 5 seconds, the system automatically jumped back to the original noise reduction mode.

Enable Developer Mode
Step 1: Download Xcode
To try the Adaptive Audio feature, first download Xcode and enable the iPhone’s iOS Developer mode.
Step 2: Start Xcode
After starting Xcode, you will see the screen shown in Figure 1. Click on “App”, then fill in the “Product Name” and “Organization Identifier” according to the instructions in Figure 2, and finally the screen shown in Figure 3 will appear. Now you can connect the iOS device you want to upgrade to the MacOS device.
▲Figure 1: Click “App”
▲Figure 2: Fill in “test” in the input fields of “Product Name” and “Organization Identifier”
▲Figure 3: After seeing this screen, you can connect your iOS device to this MacOS device
Step 3: Enable “Developer Mode” on the iOS device
After opening the “Settings” on the iPhone, click “Privacy and Security”, then enter the “Developer Mode”, and enable the “Developer Mode”, and then restart your iOS device. After restarting your iOS device is in developer mode.
▲Click “Privacy and Security” (green frame)
▲Click “Developer Mode” (shown in green box)
▲This option needs to be “On”, and then you need to restart your iOS device
Update AirPods Pro
Step 1: Enable AirPods to test “Pre-release Beta Firmware”
After rebooting, open the “Settings” on the iPhone again, click “Developer”, then enter the “Developer Mode”, and enable the “Developer Mode”, and then restart your iOS device. After restarting your iOS device is in developer mode.
▲Click “Developer” (shown in the green box)
▲Click AIRPODS to test “Pre-release Beta Firmware” (shown in green frame)
▲In the right column, select Open to test your AirPods Pro 2 (green box)
After enabling the developer mode of the iOS device and the AirPods testing “Pre-release Beta Program”, you need to charge the AirPods and place them near your iOS device. Wait for a few minutes to several hours, when you see the picture in Figure 1, or check the version of AirPods Pro 2 according to the steps in Figure 2, and see that AirPods Pro 2 has been upgraded to a version with a prefix of 6, it means your AirPods The Pro 2 has also been updated.
▲Figure 1: If you have completed the above steps and AirPods Pro 2 has also been updated, your iOS device will display this screen
Check your AirPods Pro 2 firmware version
After connecting your AirPods Pro with Bluetooth, first enter “Settings”, click on your AirPods Pro (shown in the green box in Figure 2), and then slide to the bottom to see what version your AirPods is now. If it is a version starting with “6 prefix” (shown in the green box in Figure 3), it means that your AirPods has also been successfully upgraded, and you can try “adaptability” and “dialogue perception”.
▲Figure 2: Click on your AirPods Pro
▲Figure 3: Check whether your AirPods Pro has been updated to the latest version of the “6 prefix”
Turn on the “Adaptive” and “Dialogue Awareness” functions
Enter “Settings”, select your AirPods Pro, and see the screen in Figure 1, which means you can try the latest “adaptability” and “dialogue perception” functions. In addition, you can also choose which noise control mode to use in the navigation bar (Figure 2).
▲Figure 1: Click the green box to use the “Adaptive” function
▲Figure 2: Select the noise reduction mode you need
