Hi hereisyannnng,
We understand that you'd like to know if AirPods Pro use Adaptive EQ.
AirPods Pro either use Active Noise Cancellation and Transparency mode or no noise-control. You can learn more about how this feature works with your AirPods here: AirPods Pro and AirPods Max Active Noise Cancellation and Transparency mode
"AirPods Pro and AirPods Max have three noise-control modes: Active Noise Cancellation, Transparency mode, and Off. You can switch between them, depending on how much of your surroundings you want to hear.
What are Active Noise Cancellation and Transparency mode?
With Active Noise Cancellation, an outward-facing microphone or microphones detect external sounds, which your AirPods Pro (1st or 2nd generation) or AirPods Max then counter with anti-noise, canceling the external sounds before you hear them. An inward-facing microphone listens inside your ear for unwanted internal sounds, which your AirPods Pro or AirPods Max also counter with anti-noise.
Transparency mode lets outside sound in, so you can hear what's going on around you. Active Noise Cancellation and Transparency mode work best when your AirPods Pro fit well.
If you have AirPods Pro (2nd generation) and the latest version of iOS or iPadOS, you can also use Adaptive Transparency to reduce loud sounds around you. While you're wearing your AirPods Pro (2nd generation) and they're connected to your iPhone or iPod touch, go to Settings > [your AirPods], then turn on Adaptive Transparency."
We hope this helps.
Cheers!
