You plugged your USB-C earbuds into the Nothing Phone (3) and got silence, or your Bluetooth headphones keep cutting out mid-track. Before you write off the headphones as broken, most audio failures on this phone trace back to how the device has to connect, a stale Bluetooth pairing, or a media slider sitting far lower than you think. The fixes below start with the quickest, safest checks and only move toward the official reset and support steps if nothing earlier works. Work through them in order, since the earliest steps take only seconds and clear the majority of headphone complaints on their own.
It helps to confirm what actually works before changing settings. Run a left and right audio test, note which channels and frequencies play correctly, and match the result against the steps below.
How headphones actually connect on the Nothing Phone (3)
The first thing to understand is that the Nothing Phone (3) has no 3.5mm headphone jack. Per Nothing's official support, there is no analog jack on Nothing Phone, so wired headphones can only connect through the USB-C port, while everything else connects over Bluetooth.
That means a wired set has to be a genuine USB-C headset, or standard headphones plugged in through a working USB-C-to-3.5mm adapter. If a wired pair will not produce sound, confirm it is truly USB-C compatible, or that your adapter itself is working, before you go any further. Once you know which path your headphones use, the rest of the fixes will make far more sense.
Rule out a muted or low media volume first
It sounds obvious, but a low or zero media level is one of the most common reasons audio seems dead in headphones that are actually connected. The media stream is separate from your ring and notification volumes, so it can sit muted while the rest of the phone behaves normally and still plays alerts out loud.
Go to Settings > Sound & vibration > Media volume and raise the slider to maximum. Play something with your headphones connected and listen for output before you assume there is a deeper problem to chase. If you adjust the side volume keys while audio is actually playing, the on-screen slider should move the media level rather than the ringer, which is the level that matters here.
Reseat the cable and remember wired audio outranks Bluetooth
For USB-C headphones, unplug the connector and firmly re-insert it so the contacts seat fully. A loose or partially inserted plug can pass power without passing a clean audio signal, which leaves you with intermittent sound or none at all. Try the cable or adapter with another device too, since a failing cable or adapter is a common and easily overlooked cause.
There is also an important priority rule on this phone. When a USB-C audio cable, or a 3.5mm cable through an adapter, is inserted, it takes priority and automatically disconnects Bluetooth; removing the cable triggers automatic Bluetooth reconnection. So a forgotten wired accessory can silence your Bluetooth headphones, and an active Bluetooth link can be the reason a freshly plugged cable behaves oddly. Make sure only the accessory you actually want to use is connected at the time.
Cycle Bluetooth and keep the headphones in range
If you are on Bluetooth headphones, turn the phone's Bluetooth off and back on to clear a confused connection. Confirm Bluetooth is switched on again before you try to reconnect the headphones.
Distance matters too. Keep the headphones close to the phone, with no thick walls or other busy wireless devices crowding the signal in between, then reconnect once the radio settles. It also helps to close and reopen the app you are listening in, so it re-establishes the audio route to the freshly reconnected headphones.
Restart the phone, and force a restart if it is frozen
A normal restart clears the temporary audio and Bluetooth glitches that build up while a phone stays on for days at a time. Power the phone down and back up, then test your headphones again.
If the phone is frozen or unresponsive, force a restart instead. Hold the power button and volume up button simultaneously until the Nothing logo appears on the display. If the screen is fully unresponsive, you can also long-press the power button for 15 seconds or more to force the restart.
Forget the Bluetooth headphones and pair them fresh
A stale or corrupted pairing record can keep a perfectly good headset from working. Removing the old pairing and starting over fixes a surprising number of Bluetooth audio faults.
- 1.Go to Settings > Connected devices and tap the gear or 'i' icon next to your headphones.
- 2.Choose 'Forget This Device' to clear the old pairing.
- 3.Back on Settings > Connected devices, tap Pair new device.
- 4.Put the headphones into pairing mode and select them to pair again from scratch.
Install the latest Nothing OS update
Nothing OS, which is based on Android 15, receives over-the-air updates that frequently fix audio and Bluetooth bugs. Running an outdated build can leave a known headphone issue unpatched on your phone for no reason.
Go to Settings > System > System update and check for an update. Connect to Wi-Fi, keep the battery at roughly 50 percent or higher, and do not interrupt the phone while the upgrade installs.
If your headphones are a Nothing-brand set from the Ear or Headphone series, their firmware updates separately through the Nothing X app rather than through the phone's system update. Keeping both the phone and the earbuds current rules out a version mismatch between them.
Test another app, then remove a suspect app
To find out whether the fault is system-wide or limited to one app, play audio in a different app. If your headphones work everywhere except one place, the problem is that app, not your headphones or the phone's hardware. Streaming apps, calls, and games can each route audio differently, so trying two or three of them gives you a clearer picture of where the fault sits.
If the trouble began right after you installed a third-party app, that app may be interfering with audio routing. Uninstall it through Settings > Apps > See all apps, where you select the app and tap Uninstall, or open the app's Storage & cache screen and tap Clear cache to reset it.
Factory reset only as a last resort
If headphones still refuse to work after everything above, a factory reset clears deeper software corruption. Treat this as a final software step, not an early one, because of what it erases.
Back up your data first, then go to Settings > System > Reset options > Erase all data (factory reset). Nothing warns that this clears all apps, contacts, messages, and other data and cannot be restored, and you may need your lock-screen or Google account password to confirm. Do not start this unless your important files are safely backed up somewhere else.
When to contact Nothing Customer Support
If the problem survives a factory reset, you are most likely looking at a hardware fault rather than a setting, whether that is the USB-C port or the headphones themselves. At that point, further tinkering on your own is unlikely to help.
Reach out to Nothing's official Customer Support for further assistance or service. They can advise on repair or replacement based on your phone's condition and warranty status. Have your phone's details and a short list of what you have already tried ready, as that usually speeds up the support conversation.
Frequently Asked Questions
Does the Nothing Phone (3) have a headphone jack?
No. Per Nothing's official support, there is no 3.5mm headphone jack on Nothing Phone, so wired headphones connect through the USB-C port, using a USB-C headset or standard headphones via a USB-C-to-3.5mm adapter, and other headphones connect over Bluetooth.
Why do my Bluetooth headphones go quiet when I plug in a cable?
That is expected behavior. When a USB-C audio cable, or a 3.5mm cable through an adapter, is inserted, it takes priority and automatically disconnects Bluetooth. Removing the cable triggers an automatic Bluetooth reconnection.
How do I force restart a frozen Nothing Phone (3)?
Hold the power button and volume up button simultaneously until the Nothing logo appears on the display. If the screen is fully unresponsive, you can instead long-press the power button for 15 seconds or more.
Will a factory reset fix my headphone problem?
It can resolve deep software faults, but use it only as a last resort. Nothing warns that a factory reset, found at Settings > System > Reset options > Erase all data, clears all apps, contacts, messages, and other data and cannot be restored, so back up first.
How do I update my Nothing Phone (3) software?
Go to Settings > System > System update and check for an update. Connect to Wi-Fi, keep the battery at roughly 50 percent or higher, and avoid interrupting the phone during the upgrade.
