Adjust audio and visual settings on iPhone
You can adjust audio and visual accessibility settings to suit your hearing needs. For example, set mono audio, volume balance, phone noise cancellation, LED Flash for Alerts, and headphone accommodations.
Adjust the volume balance and mono audio
- Go to Settings > Accessibility > Audio/Visual.
- Adjust any of the following:
- Mono Audio: Combine the left and right channels into a mono signal played on both channels.
- Balance: Drag the Left Right Stereo Balance slider.
Control noise cancellation on iPhone
Noise cancellation reduces ambient background noise on phone calls when you’re holding the receiver to your ear.
- Go to Settings > Accessibility > Audio/Visual.
- Turn Phone Noise Cancellation on or off.
Flash the LED for alerts
If you can’t hear the sounds that announce incoming calls and other alerts, iPhone can flash its LED (next to the camera lens on the back of iPhone). The LED flashes only if iPhone is locked.
Tip: LED Flash for Alerts is a useful feature for anyone who might miss the tones associated with calls and other alerts in a noisy environment.
- Go to Settings > Accessibility > Audio/Visual, then turn on LED Flash for Alerts.
- To prevent LED flashes when iPhone is in silent mode, turn off Flash on Silent.
Set headphone accommodations
With supported Apple and Beats headphones, you can amplify soft sounds and adjust certain frequencies to suit your hearing. These adjustments help music, movies, phone calls, and podcasts sound more crisp and clear. If you have an audiogram in the Health app , you can use the audiogram to customize your audio.
- Go to Settings > Accessibility > Audio/Visual > Headphone Accommodations, then turn on Headphone Accommodations.
- Tap Custom Audio Setup, then follow the onscreen instructions. Or manually set any of the following:
- Tune Audio For: Choose Balanced Tone, Vocal Range, or Brightness.
- Level: Choose Slight, Moderate, or Strong amplification of soft sounds.
- Phone: Apply these audio settings to phone calls.
- Media: Apply these audio settings to media playback.
- Transparency Mode: Turn on Custom Transparency Mode and adjust the amplification, balance, and tone to help you hear what’s happening around you (available when you have AirPods Pro connected to iPhone).
