- Turn OFF EQ to hear the natural flat response of AirPods
Volume Limit (Legacy iOS)
Older iPhones include a hard volume cap setting.
- Found under: Settings > Music > Volume Limit
- Ensure the slider is fully to the right
Mono Audio Setting
Mono audio duplicates one channel across both earbuds.
- Misuse results in perceptual drop in soundstage or imaging
- Should remain OFF for stereo content
What is audio balance and how does it impact AirPods?
Audio balance controls left-right channel amplitude. When shifted, it causes one AirPod to sound much quieter than the other, even at full volume.
Sub-entities Impacting Audio Balance
Accessibility Settings
Audio balance slider resides in iOS Accessibility settings and syncs via iCloud.
iCloud Sync Behavior
Balance settings can propagate across devices via iCloud, affecting multiple AirPods pairings.
OS Update Bugs
Updates occasionally reset or modify balance to accommodate hearing safety policies.
External App Interference
Music and podcast apps with custom EQ engines may override system audio balance, especially on older iOS versions.
AirPods rely on a stable stereo channel feed. Any shift toward one channel distorts perceived audio volume.
How do I turn off Reduce Loud Sounds on iOS?
Disabling this feature allows full playback amplitude through AirPods without iOS automatically limiting the output level.
Steps to Disable:
- Go to Settings > Sounds & Haptics
- Tap Headphone Safety
- Toggle OFF Reduce Loud Sounds
- Drag the slider to 100 dB before turning off if needed
This setting directly affects loudness and especially impacts AirPods Pro with ANC enabled. Many users unknowingly have this setting activated after iOS updates, leading to volume concerns.
Why are my AirPods quieter than before after an iOS update?
Post-update configurations often include reset volume caps, enabled “Reduce Loud Sounds,” or altered Bluetooth codec priorities.
Update Triggers
- Re-enabled Headphone Safety with decibel limits
