Frequency response notes (measured)iMeasured by a reviewer, not claimed by the maker

HeadphonesAddict reports a U-shaped response with elevated sub-bass. Its ANC-off response is more balanced, while ANC-on lifts treble. The reviewer says Adaptive EQ may affect the measured response.17Reviewheadphonesaddict.com/apple-airpods-pro-2-usb-c-reviewRead 7 October 2026Exact USB-C review publishes separate ANC on/off graphs. Method: MiniDSP H.E.A.R.S. and REW, 20 Hz-20 kHz sweeps, 94 dB earbuds baseline at 300 Hz, five repositioned measurements averaged with 1/12 smoothing. Target is its flat reference, not Harman. Test host, codec, firmware and tips are not stated. These notes retain the reviewer’s measured response description without inventing numeric target deviations.

Default sound over-emphasizes bass by a couple of dB against the SoundGuys target and under-emphasizes the mids around 500 Hz and 3 kHz by up to 5 dB.
