Apple AirPods Pro (2nd generation) Truly Wireless Review

The Apple AirPods Pro 2 have an adaptive EQ, and when on, they have a slightly warm sound profile, which is great if you like genres with a bit more bass or if you like your vocals and instruments to sound cozier in your mixes. Compared to their Apple AirPods Pro Truly Wireless, they also have better bass extension, which helps improve the depth of bass in your audio. Overall, their sound is quite versatile and is well-suited for a variety of audio content. However, there are no built-in EQs or presets to help you tweak their sound. If you’re an iOS user, you can access sound customization features in your settings via the ‘Accessibility’ tab.

Thanks to their H2 chip, these headphones can adjust their bass and treble response, depending on the listening volume. However, this is only noticeable when connected to an iOS device. This change is to mitigate the effects of equal-loudness contours (and more specifically, the Fletcher-Munson curve). To simplify, this research explores the perception of constant sound pressure based on listening volume. At high volumes, the listener perceives more bass and treble than mid. However, at low volumes, the listener perceives less bass and treble than mid. These headphones counter this issue in their frequency response by increasing bass and treble at lower volumes to encourage people to listen to audio at lower volumes. You can see the change in frequency response when using an iOS device with ANC on and ANC off. This effect isn’t applicable to PCs or Android devices.

Note: There’s a slight discrepancy between the left and right driver in the raw frequency response graphs. It’s due to how the files were processed and level-matched. However, all other graphs are correct, and this difference isn’t audible. We also don’t expect users to encounter this issue with their own units.
