Where to find headphone settings on your iPhone

Headphone settings on iPhone live in the Settings app, under a section called Accessibility. Open Settings, scroll down past the first few options, and tap Accessibility. From there, look for Audio/Visual near the middle of the list. This is where most headphone controls live, though some settings scatter across other parts of Settings depending on what you want to change.

If you're looking for volume controls or basic audio output, those are in Settings > Sounds & Haptics instead. The distinction matters: Sounds & Haptics handles ringer volume and notification sounds, while Audio/Visual handles how audio plays through headphones and speakers during calls, videos, and accessibility features.

Key Takeaways

  • Most headphone settings are in Settings > Accessibility > Audio/Visual, where you can adjust mono audio, balance, and call audio routing.
  • Volume limits for headphones are set in Settings > Sounds & Haptics, and you can lock them with a passcode to prevent accidental changes.
  • Bluetooth headphone pairing happens in Settings > Bluetooth, and you can forget a device there if it stops connecting properly.
  • Spatial audio and surround sound settings appear in the Music or TV app itself, not in the main Settings menu.
  • If headphones aren't working, check Settings > Bluetooth to confirm they're connected, and restart both the iPhone and headphones.

Adjusting volume limits and safety settings

Go to Settings > Sounds & Haptics > Headphone Safety. Here you can set a maximum volume limit so headphones never play louder than a level you choose. Slide the volume bar to your preferred cap, then toggle on Reduce Loud Sounds if you want the iPhone to automatically lower sudden loud noises.

To lock this limit so it can't be changed without your permission, tap Use Volume Limit and then Lock Volume Limit. You'll be asked to create a four-digit code. This is useful if children use your iPhone or if you want to protect your hearing without accidentally turning the limit off during a call.

Turning mono audio on or off

If you have hearing loss in one ear, mono audio combines left and right channels into a single channel that plays through both sides of your headphones. Go to Settings > Accessibility > Audio/Visual and toggle Mono Audio on. When it's on, you'll hear the full mix in both ears instead of missing sounds that would normally come from one side.

You can also adjust the balance slider just below Mono Audio to shift sound toward the left or right ear if you prefer not to use full mono. This is useful if one ear works better than the other but you still want stereo sound.

Changing how audio routes during phone calls

When you're on a call, your iPhone normally routes audio through the speaker at the top of the phone, not through headphones, unless headphones are already connected. If you want to change this behavior, go to Settings > Accessibility > Audio/Visual and look for Call Audio Routing. Tap it and choose whether calls should default to Speaker, Bluetooth Headset, or Automatic.

Automatic is the safest choice for most people—it will use whatever audio device is already connected. If you choose Speaker, calls will play through the speaker even if headphones are plugged in, which can be jarring. Choose Bluetooth Headset only if you always wear the same headphones during calls.

Managing Bluetooth headphone connections

To pair new Bluetooth headphones, go to Settings > Bluetooth and make sure Bluetooth is toggled on. Put your headphones into pairing mode (check the manual for how—usually it's holding a button for a few seconds), and they should appear in the list under "Other Devices." Tap the name to connect.

If headphones won't connect or keep disconnecting, go back to Settings > Bluetooth, find the headphones in the list, tap the info icon (the small circle with an "i"), and select Forget This Device. Then repeat the pairing process from scratch. This clears out old connection data that sometimes causes problems.

Enabling spatial audio and surround sound

Spatial audio creates a three-dimensional sound effect in compatible headphones during movies and shows. This setting isn't in the main Settings app—it's inside the app where you're watching. Open the Apple TV app or Apple Music app, start playing a video or song, and look for an audio icon (usually three dots or a speaker symbol). Tap it and toggle Spatial Audio on if the option appears.

Not all content supports spatial audio, and not all headphones can play it. AirPods Pro and AirPods Max are the most common headphones that support it. If the toggle doesn't appear, the video or song doesn't have spatial audio mixed in.

Fixing headphones that aren't working

Start by checking Settings > Bluetooth to confirm your headphones are connected. If they're listed but show as disconnected, tap the info icon and forget the device, then pair them again. If they don't appear in the list at all, make sure they're in pairing mode and try again.

For wired headphones, check that the cable is fully inserted into the headphone jack (if your iPhone model has one—newer iPhones don't). Try a different pair of headphones if you have them. If nothing works, restart your iPhone by holding the power button and swiping to power off, waiting ten seconds, then powering back on. Also restart your Bluetooth headphones by turning them off and on again.

Frequently Asked Questions

Can I set different volume limits for different apps?

No, the volume limit in Settings > Sounds & Haptics applies to all audio on your iPhone. However, individual apps like Spotify or YouTube have their own internal volume controls that work within that limit. The iPhone's limit is a hard cap that nothing can exceed.

Why do my headphones keep disconnecting from Bluetooth?

This usually happens when the headphones are too far from your iPhone (more than 30 feet), when another device is trying to connect to them, or when the pairing data is corrupted. Try forgetting the device in Settings > Bluetooth and pairing again. If it keeps happening, restart both the headphones and iPhone.

Do I need to turn off Bluetooth when I'm not using headphones?

You don't have to, but turning off Bluetooth when you're not using wireless headphones saves battery life. Go to Settings > Bluetooth and toggle it off. You can also use Control Center—swipe down from the top right and tap the Bluetooth icon to toggle it quickly.

What's the difference between mono audio and balance adjustment?

Mono audio combines both channels into one, so you hear everything in both ears equally. Balance shifts the volume between left and right ears but keeps stereo sound. Use mono if one ear doesn't work well; use balance if both ears work but one is stronger.

Can I use headphones with an older iPhone the same way?

Yes, the settings are in the same places on older iPhones. The main difference is that iPhones 6s and earlier have a headphone jack, so wired headphones plug in directly. iPhone 7 and newer require Bluetooth headphones or a Lightning adapter with wired headphones.
