Bluetooth audio that keeps cutting out on a Mac is usually caused by interference, low battery, a weak connection, incorrect audio settings, or a temporary macOS or Bluetooth problem. Start by charging the headphones or speaker, moving it closer to the Mac, disconnecting other Bluetooth devices, and reconnecting the audio device. If that does not help, work through the steps below.
Quick Answer
- Charge the Bluetooth headphones, earbuds, or speaker.
- Keep the device within a few feet of the Mac and remove obstructions.
- Turn Bluetooth off and back on in Control Center.
- Select the correct output in System Settings > Sound.
- Forget and reconnect the audio device.
- Restart the Mac and the Bluetooth accessory.
- Test with other audio apps and, if possible, another Bluetooth device.
- Install available macOS updates and check whether nearby wireless devices are causing interference.
If audio still cuts out with multiple Bluetooth devices, the problem may involve the Mac’s Bluetooth hardware, system software, or wireless interference rather than the headphones themselves.
1. Check the Bluetooth Audio Device
Before changing Mac settings, rule out simple problems with the headphones, earbuds, or speaker.
Charge the device
Low battery can cause dropouts, distorted sound, or repeated disconnects. Charge the device fully, then test it again. If you are using wireless earbuds, place both earbuds in their charging case and charge the case as well.
If the device uses replaceable batteries, install fresh batteries. Some accessories continue to appear connected even when their battery is too low for reliable audio.
Move the device closer
Bluetooth is designed for short-range connections. Keep the audio device near the Mac while testing—ideally within a few feet. Avoid placing the Mac behind a monitor, inside a cabinet, or under a desk surrounded by metal objects.
Do not test from another room. A connection that works nearby but cuts out at a distance may be affected by range, walls, or interference.
Test the accessory with another device
Connect the headphones or speaker to an iPhone, iPad, or another computer. If the audio cuts out there too, the accessory may need charging, a firmware update, repair, or replacement.
If it works normally with another device, continue troubleshooting the Mac.
2. Reduce Wireless Interference
Bluetooth shares the 2.4GHz radio spectrum with some Wi-Fi networks and many other wireless devices. Interference can make audio stutter even when the Bluetooth connection does not fully disconnect.
Temporarily move the Mac and audio device away from:
- Wi-Fi routers and mesh network nodes
- USB 3 hubs, docks, and external drives
- Wireless keyboards and mice
- Game controllers
- Cordless phones and other radio transmitters
- Crowded areas with many nearby Bluetooth devices
If your Mac is connected to a 2.4GHz Wi-Fi network, try switching to a 5GHz or 6GHz network if your router supports it. This can reduce congestion, although it will not fix every Bluetooth problem.
Also disconnect Bluetooth devices you are not using. A keyboard or mouse usually does not need to be removed permanently, but temporarily disconnecting extra devices helps determine whether the Mac is managing too many active connections.
3. Confirm the Correct Audio Output
The Mac may be connected to your headphones while sending sound to another output, or an app may be using a different audio device.
- Open Control Center from the menu bar.
- Select Sound.
- Choose your Bluetooth headphones, earbuds, or speaker.
- Play audio and check whether the connection remains stable.
You can also check the setting in macOS:
- Open the Apple menu and choose System Settings.
- Select Sound.
- Under Output & Input, select the Bluetooth audio device.
- Adjust the Output volume if necessary.
If the device appears as an input option, avoid selecting it as the microphone unless you need to use its built-in microphone. Bluetooth headsets can switch into a lower-quality hands-free mode when their microphone is active. This may make audio sound worse and can sometimes contribute to unstable playback.
Quit video-call, meeting, voice-chat, and recording apps temporarily. Then test audio in a normal music or video app.
4. Disconnect and Reconnect the Bluetooth Device
A fresh connection often clears a temporary communication error.
- Open System Settings.
- Select Bluetooth.
- Find the audio device in the list.
- Click the Info button next to it, if shown.
- Choose Disconnect.
- Wait a few seconds, then click Connect.
If the device does not reconnect, turn it off, wait several seconds, and turn it back on. Put earbuds or headphones into pairing mode according to the manufacturer’s instructions.
You can also toggle Bluetooth:
- Open Control Center from the menu bar.
- Select Bluetooth.
- Turn Bluetooth off.
- Wait about 10 seconds.
- Turn Bluetooth back on.
- Reconnect the audio device.
If Bluetooth itself is missing, unavailable, or failing to turn on, follow a broader guide to fixing Bluetooth not working on a Mac.
5. Forget and Pair the Device Again
Removing the saved Bluetooth connection and pairing the device again can fix corrupted or incomplete pairing information.
Warning: This removes the device from the Mac’s saved Bluetooth connections. It does not erase files from the Mac or reset the headphones, but you will need to pair the device again.
- Open System Settings.
- Select Bluetooth.
- Find the affected device.
- Click the Info button next to it.
- Choose Forget This Device or Remove, depending on the options shown.
- Confirm the removal.
- Put the headphones or speaker into pairing mode.
- Find it under nearby Bluetooth devices.
- Click Connect and follow any prompts.
After pairing, select the device under System Settings > Sound and play audio for several minutes.
If the accessory is still connected to a phone, tablet, or another computer, turn Bluetooth off on those devices temporarily. Some headphones automatically switch between remembered devices, which can interrupt Mac audio.
6. Restart Both Devices
Restarting clears temporary software and connection states.
- Turn off the Bluetooth headphones, earbuds, or speaker.
- Save your work on the Mac.
- Close apps that are playing or recording audio.
- Open the Apple menu and choose Restart.
- After the Mac starts, turn on the Bluetooth audio device.
- Reconnect it through Control Center or System Settings > Bluetooth.
If the Mac cannot restart normally, avoid holding the power button unless necessary. A forced shutdown can cause unsaved work to be lost. Use it only when the Mac is unresponsive.
7. Check Individual Apps and Audio Settings
If Bluetooth audio cuts out only in one app, the Bluetooth connection may not be the main problem.
Test sound in at least two apps, such as a browser and the Music or TV app. If only one app has trouble:
- Quit and reopen the app.
- Check the app’s volume and output settings.
- Close other apps that use the microphone.
- Try a different audio source.
- Update the affected app if an update is available.
A browser tab, meeting app, or game may take control of the audio device or microphone. Close those apps temporarily and test again.
Also check whether the problem happens only during calls. During a call, Bluetooth headsets may switch audio profiles to support the microphone. This can reduce sound quality and change how the connection behaves. If possible, use the Mac’s built-in microphone or a separate microphone for testing.
8. Install macOS and Accessory Updates
Software updates can correct Bluetooth, audio, and device-compatibility problems.
To check for macOS updates:
- Open the Apple menu.
- Choose System Settings.
- Select General.
- Choose Software Update.
- Install any available update after saving your work.
If the headphones or speaker has a companion app, open it and check for firmware updates. Follow the manufacturer’s instructions carefully. Keep the accessory charged during the update, and do not turn it off unless the app tells you to.
9. Test in Safe Mode or With a New User Account
Third-party software can interfere with audio routing, Bluetooth utilities, VPNs, system cleaners, or device-management tools. A limited startup test can help identify that type of conflict.
Safe Mode instructions vary depending on whether your Mac has Apple silicon or an Intel processor. Apple’s startup procedure is different for each type, so use the method appropriate for your Mac. After starting in Safe Mode, connect the Bluetooth device and play audio.
If the problem disappears in Safe Mode, recently installed software, login items, extensions, or utilities may be involved. Review System Settings > General > Login Items and temporarily disable nonessential items. Restart normally after each change so you can identify the cause.
You can also test with another macOS user account. If Bluetooth audio works there, the problem is likely limited to settings or software in your usual account.
10. Reset the Bluetooth Accessory
Many headphones and speakers have a factory reset procedure. This can remove old pairing records and correct problems that persist after forgetting the device on the Mac.
Warning: A factory reset may erase the accessory’s saved devices, custom settings, equalizer preferences, or other personal configuration. It may also disconnect the device from every phone and computer.
Look up the reset procedure in the accessory’s manual or the manufacturer’s support app. After resetting it:
- Turn Bluetooth off on nearby devices.
- Reset the headphones or speaker.
- Put it into pairing mode.
- Open System Settings > Bluetooth on the Mac.
- Pair the device again.
- Test audio before reconnecting other devices.
Do not use a reset procedure from a different model. Button combinations vary between products.
Troubleshooting Specific Symptoms
Audio cuts out when the Mac is under heavy load
Close unnecessary apps and browser tabs, especially those using video, voice chat, recording, or screen sharing. Then test again. If dropouts occur only during demanding tasks, check whether a dock, USB hub, or external drive is positioned close to the Mac or Bluetooth device.
The audio pauses when you use a mouse or keyboard
Disconnect other Bluetooth accessories one at a time. If the problem stops, reconnect them individually to find the device or connection that contributes to the issue. A Bluetooth mouse that repeatedly disconnects may require separate troubleshooting; see this guide to fixing a Bluetooth mouse that keeps disconnecting from a Mac.
Only one earbud cuts out
Check that both earbuds are charged and seated correctly in the charging case. Clean the charging contacts carefully with a dry, lint-free cloth. Re-pair the earbuds and test them with another device. If the same earbud fails elsewhere, the issue is probably with the earbud or case rather than the Mac.
Bluetooth disconnects whenever the Mac wakes
Forget the device, restart the Mac, and pair it again. If the issue returns after sleep, disconnect unnecessary Bluetooth accessories and install available macOS and accessory updates.
Nothing fixes the problem
Test a different Bluetooth audio device with the Mac. This comparison is important:
- If only one device fails, troubleshoot or replace that accessory.
- If every Bluetooth audio device fails, investigate the Mac, macOS, interference, or third-party software.
- If wired audio also fails, check the app and broader sound settings rather than Bluetooth alone.
If the problem remains after updates, re-pairing, interference testing, and Safe Mode testing, contact Apple Support or an authorized service provider. Describe whether the issue affects one accessory or all Bluetooth audio devices, whether it occurs in every app, and whether it continues in Safe Mode.
Frequently Asked Questions
Why does Bluetooth audio keep cutting out on my Mac?
Common causes include low battery, distance, wireless interference, an incorrect audio output, outdated software, or a damaged accessory. Start by charging the device, moving it closer, and reconnecting it.
Will forgetting a Bluetooth device delete anything?
No. Forgetting a Bluetooth device removes its saved pairing from the Mac. It does not delete files from the Mac or erase the accessory. You will need to pair the device again.
Can Wi-Fi interfere with Bluetooth audio?
Yes. Bluetooth and some Wi-Fi networks use the 2.4GHz band. Switching the Mac to a 5GHz or 6GHz Wi-Fi network, when available, may reduce interference.
Why does Bluetooth audio sound worse during calls?
Many Bluetooth headsets change audio profiles when their microphone is active. This can reduce playback quality. Test with the Mac’s built-in microphone or another microphone to see whether the headset profile is involved.
Should I reset the Mac’s Bluetooth settings?
For most users, forgetting and pairing the device again is safer than manually deleting system files or running reset commands. Avoid Terminal-based resets unless you understand the changes and have a specific reason to use them.
Final Thoughts
Most Bluetooth audio dropouts on a Mac can be resolved by charging the accessory, reducing interference, selecting the correct output, and pairing the device again. If multiple accessories continue to cut out after updates and Safe Mode testing, the problem may require Apple or accessory-manufacturer support.
