Custom EQ · dB

Manual EQ uses the A3951 combined EQ/HearID packet and preserves the current HearID data. It does not run a new hearing test.

Channel test

Play a short low-level tone in the left channel, right channel, or both. Test audio uses your current system audio output and does not change earbud settings.

Ready

Test levelStarts low. Set your computer volume conservatively before testing.

10%

For a meaningful test, choose Liberty Air 2 Pro as your operating system's audio output first. PairPanel does not request microphone permission just to select a speaker.
