Audio distortion in headphones can ruin calls, music, and videos on your OnePlus 15. You may hear crackling, muffled sound, or uneven volume that comes and goes. This issue is usually caused by simple software settings, connection problems, or audio processing features that need adjustment.
Why Your OnePlus 15 Has Audio Distortion in Headphones
- The headphone jack or USB-C port has dust or debris.
- Bluetooth audio settings are conflicting with the codec in use.
- Sound enhancement features are overprocessing audio.
- The headphones themselves are not fully compatible.
- Temporary system glitches after updates in 2025.
1. Restart Your Phone
Restarting clears temporary audio glitches and refreshes the sound drivers. This step often fixes distortion that suddenly appears without warning.
Swipe down from the top of the screen, and then tap the Power icon.
Tap Restart, and then wait for the phone to boot back up fully.
2. Check the Headphones on Another Device
Testing your headphones on another phone helps confirm whether the issue comes from the OnePlus 15 or the headset itself. If distortion follows the headphones, the problem is likely hardware-related.
Connect the headphones to another phone, and then play music or a video.
Listen carefully, and then compare the audio quality.
3. Turn Off Sound Enhancement Features
Audio enhancement features can sometimes overprocess sound, causing crackling or distortion. Disabling them helps deliver a cleaner, more natural output.
Open Settings, and then tap Sound and vibration.
Tap Audio effects, and then turn off any sound enhancement options.
4. Reset Bluetooth Audio Settings
For wireless headphones, Bluetooth settings can become unstable over time. Resetting them forces the phone to establish a fresh audio connection.
Open Settings, and then tap Bluetooth.
Tap the connected headphones, and then select Forget.
Reconnect the headphones and test the sound again.
5. Clean the Audio Port
Dust or lint in the port can interfere with audio signals, especially with wired headphones. Cleaning it carefully can restore proper contact.
Turn off the phone, and then inspect the port under good lighting.
Use a soft brush or compressed air to gently clean it.
6. Update the System Software
Software updates often include audio bug fixes and performance improvements. Keeping your phone updated reduces the chance of persistent sound issues.
Open Settings, and then tap System updates.
Check for updates, and then install any available version.
Most headphone distortion issues on the OnePlus 15 are easy to fix once you identify the cause. After adjusting audio settings or refreshing connections, sound quality usually returns to normal.
FAQs
Why does distortion only happen at high volume?
At high volume levels, audio drivers and headphones are more likely to distort. Lowering the volume slightly often eliminates the issue.
Does Bluetooth codec affect sound quality on OnePlus 15?
Yes. Different codecs handle audio differently, and some headphones perform better with specific codecs supported by the phone.
Should I replace my headphones if distortion keeps happening?
If the issue persists across multiple devices, the headphones may be damaged. Replacing them is the best long-term solution.
