How To Fix Muffled Sound on Bluetooth Headphones (Win 10/11)

You can resolve software and driver-related issues by checking the Windows sound settings and device manager and updating the Bluetooth audio drivers. But You can only fix the hardware-related issues by servicing or replacing the headphone.
- Audio Source Issues
Another audio output source attached to your computer likely conflicts with your Bluetooth headphones. As a result, you are experiencing muffled sounds from your headphones. This conflict distorts the audio signals affecting the sound of your Bluetooth headphones.
You can solve this issue only by selecting your Bluetooth headphones as your default audio device. You will have to select its drivers as default as well. For this, first, click on the speaker icon on the bottom right corner of your taskbar and change the audio drivers for your headphones.

Bitrate settings are the sound settings that allow you to adjust the sound quality. Incorrect settings can lead to distorted and muffled sounds in headphones. Headphones are usually set to a bitrate of 48KHz, but you can adjust this to higher or lower bitrates depending on your preference.

At the backend of your hardware, drivers act as a bridge between the hardware and the software. Using outdated sound drivers or corrupt audio drivers can also cause sound to be muffled or distorted. These drivers don’t support your headphones or Bluetooth. As a result, you hear the muffled sound.
To update your Bluetooth drivers, open “Device Manager” and click the Bluetooth device icon. Now select the “Update” option from the file menu. Another option window will pop up. Select the “Search automatically for drivers” option.

To eliminate this problem, ensure that all of these are current and do not miss an important update.
Open the Windows search bar and, type “Check for updates,” open the settings. Once you are in the settings, click “View optional updates,” Here, you can find the list of Windows additional updates. If any update is related to audio or Bluetooth, install it immediately to avoid the issue.
- Windows Audio Enhancement Settings

A window will pop up where you need to select the option named “System.” Select the “Sound” option from the list on your left-hand side in the next window to appear. Now, open the “Device Properties.”
Select the title with the blue text “Additional Device Properties” on the next user interface. Now, a small window with multiple tabs will appear where you need to open the tab named “Enhancements.” You can enable and disable the Windows audio enhancement settings and sound effects here.

- Wireless Connection Issues
Wireless connectivity is the key aspect to consider when discussing Bluetooth headphones. As Bluetooth headphones use a wireless connection, they are prone to lose their connectivity in the area with more wireless devices or when more than one device is connected to your computer.
Due to this unstable connection, your headphones may have a muffled sound issue. To avoid this issue, remove all other sound devices (wired or wireless) from your computer/laptop.

The greatest enemy of any electronic device is water. Even a few drops of water can damage the internal components of your Bluetooth headphone, causing sound muffling or distortion. Water has salts and minerals in it that can conduct electricity. Hence they cause a short circuit in your devices.
Apart from this, water can also cause short circuits in the headphone hardware. Such short circuits also cause unwanted sounds while using headphones and often suppress the sound. To avoid such issues, keep your headphones away from your drinks and use a waterproof headphone cover.
- Accumulated Debris in Headphone
Due to constant usage, the headphone speakers can get clogged with dust particles and debris. This debris in the speakers acts as an obstacle and doesn’t let them vibrate properly. As a result, sound waves do not produce properly. It results in a muffled sound in your Bluetooth headphones.
