You plug your USB-C earbuds into the Huawei Pura 70 Pro expecting your playlist, and instead you get silence, sound that only comes from the phone speaker, or a Bluetooth headset that pairs but refuses to play. Because this phone has no 3.5mm headphone jack, every wired connection runs through the USB Type-C earjack, and everything else goes over Bluetooth 5.2, so the fix depends on which path you are using. The good news is that most "no audio" problems on EMUI 14.2 come from a temporary routing glitch, a loose plug, or a Bluetooth setting, not a broken phone. Work through the steps below in order, starting with the quickest and safest, and only reach for a reset near the end.
Start With a Clean Restart
A simple restart clears the temporary audio-routing glitches that often cause sudden silence, and it costs you nothing. On the Pura 70 Pro, press and hold the Power button until your phone displays the Power off and Restart menu, then touch Restart. Once it boots back up, reconnect your headphones and play something to test.
If the screen is frozen and the menu will not appear, force a restart instead by pressing and holding the Power button for 10 seconds or longer. The phone will reboot on its own, after which you can try your headphones again.
Check the USB-C Port and Reseat Your Wired Headphones
Since the Pura 70 Pro routes all wired audio through the USB Type-C earjack, a dirty or obstructed port is a common cause of dropouts and dead channels. Shine a flashlight into the port and look for lint, dust, or any foreign object, then gently clear out any debris you find.
- 1.Inspect the USB-C port with a flashlight for liquid or foreign objects and remove any debris.
- 2.Remove the headset completely.
- 3.Reinsert the plug firmly and push it all the way in so it seats with secure contact.
- 4.Play audio to confirm both sides are working.
If you see signs of liquid inside the port or suspect water has reached the phone, stop here. Back up your data and take the device to an authorized Huawei Customer Service Center rather than forcing a damp connector.
Turn On Media Audio and Call Audio for Bluetooth
If your wireless headphones connect successfully but play no sound, the phone may simply not be routing audio to them. Go to Settings > Bluetooth, open the connected earphones' settings, and enable Media audio and Call audio. With both enabled, music and call audio will flow to the headset instead of staying on the phone.
After changing those toggles, restart whatever audio player you were using and try again. If the problem only happens during a phone call, switch the audio output to the earphones from the in-call screen so the voice path uses your headset.
Pair Your Wireless Earbuds Again From Scratch
A stale or half-finished pairing can leave Bluetooth headphones connected in name only. Removing and re-pairing them forces a fresh handshake. The exact pairing-mode step depends on your earbuds; the sequence below uses HUAWEI FreeBuds as the example.
- 1.Place the earbuds in the charging case and keep the lid open.
- 2.Press and hold the Function button for about 2 seconds until the indicator flashes, which puts them in Pairing mode.
- 3.On the phone, go to Settings > Bluetooth.
- 4.Touch the name of the earbuds in the device list to pair.
If pairing still fails, you can restore the earphones to their factory settings using their own reset procedure and then connect them again. For ongoing management of HUAWEI wireless earbuds, the HUAWEI AI Life app or the HUAWEI Audio Connect app (available from the app store or AppGallery) is the tool Huawei recommends; no companion app is needed for basic wired USB-C use.
Swap Headsets to Find the Real Culprit
Before you change anything else on the phone, it helps to know whether the fault lives in the headphones or in the device. Testing with a second headset, or testing your headset on a second phone, isolates the problem quickly.
If you use a HUAWEI headset, try it on another HUAWEI phone. When the issue follows the headset to the other phone, the headset itself may be damaged. For a non-HUAWEI headset, try a HUAWEI headset on your Pura 70 Pro to confirm the accessory is actually compatible with the phone.
Look Closely at Your USB-C Adapter
If you are connecting older wired earphones through a USB-C adapter, the adapter is a frequent point of failure. Switch to the original, directly compatible headset and play audio again. If sound returns with the direct connection, the adapter is incompatible and should be replaced with a compatible one.
Reset the Network Settings to Unstick Bluetooth
When Bluetooth pairing problems keep returning no matter how many times you reconnect, resetting the network settings often clears the stuck state without touching your personal files. Go to Settings > System & updates > Reset and touch Reset network settings. This resets your Wi-Fi, mobile data network, and Bluetooth settings; it will not change any other settings on your phone or delete any data.
After the reset finishes, pair your headphones again from Settings > Bluetooth as described earlier. You will also need to reconnect to your Wi-Fi networks, since those credentials are cleared by this step.
Install the Latest EMUI Update
Audio bugs are sometimes resolved in firmware, so keeping EMUI 14.2 current can fix a problem you cannot see. Go to Settings > System & updates > Software update, then choose New version > Download & install. Connect to Wi-Fi while downloading to avoid using your mobile data, and let the phone finish installing and restart before you test your headphones again.
Factory Reset When Nothing Else Clears the Fault
A factory reset is a last resort because it wipes the phone, so only use it once the steps above have failed. To start it, go to Settings > System & updates > Reset > Reset phone, touch Reset phone, and follow the onscreen instructions.
Before you do, read Huawei's warning carefully: "This operation will erase all the data on your phone, including your accounts, app data, system settings, installed apps, music, images, and all files on the internal storage. Make sure to back up your data before restoring your phone to its factory settings." Back up everything you care about first, then proceed only if you are sure.
If the phone is too unresponsive to reach the menu, you can reach the same reset through Recovery mode: press and hold down on the Power and Volume up buttons until Recovery mode displays, then select Clear data > Reset phone. The same data-loss warning applies, so a backup beforehand is essential.
Bring It to Authorized Huawei Support
If your headphones still do not work after a factory reset, the most likely explanation is a hardware fault in the port or the audio components. At that point, back up your data, then take your device together with your proof of purchase to an authorized Huawei Customer Service Center. The technicians there can diagnose the port or board and handle any repair under the correct terms, which is safer than opening or forcing the phone yourself.
Frequently Asked Questions
Does the Huawei Pura 70 Pro have a 3.5mm headphone jack?
No. Huawei's official specifications list only a USB Type-C earjack (digital audio over USB-C) and Bluetooth 5.2. That means "headphones" on this model are either USB-C wired headphones, wired earphones connected through a compatible USB-C-to-3.5mm adapter, or wireless Bluetooth headphones and earbuds.
My Bluetooth earbuds connect but play no sound. What do I do?
Go to Settings > Bluetooth, open the connected earphones' settings, and enable Media audio and Call audio. Then restart your audio player and try again. If audio is missing only during calls, switch the audio output to the earphones from the in-call screen.
Will resetting the network settings delete my photos or files?
No. Reset network settings, found under Settings > System & updates > Reset, only resets your Wi-Fi, mobile data network, and Bluetooth settings. It does not change your other settings or delete any data, though you will need to reconnect to Wi-Fi and re-pair your devices afterward.
How do I force restart a frozen Pura 70 Pro?
Press and hold the Power button for 10 seconds or longer. This forces the phone to restart even when the screen is unresponsive, after which you can reconnect your headphones and test the audio.
