How to solve the distortion of the sound of a cell phone Bluetooth headset

If the Bluetooth headset can be paired, the sound appears to have numerous issues. For example, the sound quality may be lower than intended, or the sound may be intermittent. These circumstances may suggest a Bluetooth connectivity issue. This article explains how to fix distorted sound from Bluetooth headsets for cell phones.

1. Examine the music's source. Check the sound file's quality before you begin debugging the Bluetooth connection. Many streaming media services are configured to use lower-bit-rate MP3 files. Next, test using another pair of Bluetooth headphones to check whether this is a Bluetooth failure. Lastly, ensure that the Wi-Fi or cell phone signal is strong. If the network connection is too slow to transfer Spotify audio smoothly, the sound may become distorted or stutter.

2. Re-pair your Bluetooth headset. As with all troubleshooting, "turn it off and back on" should be the reflex of many people when there is a problem with their Bluetooth headset. Unpair the headset and turn it off, then restart your phone's Bluetooth function and start pairing from the beginning.

3. Bring the Bluetooth headset closer to the media player. When the distance between the Bluetooth headset and the connected device is too great, or there are too many impediments in the way, the signal transmission between them is disrupted, resulting in distorted or stuttering sounds. To check whether it helps, get close to the playing device and avoid other electrical equipment that generates signals.

4. Properly pair monaural. Many true wireless Bluetooth headphones can be worn in one ear, but they need to be done correctly. Check the manual for the correct way to listen in one ear.

5. Disconnect from other devices. Bluetooth audio may be distorted if the phone is connected to other Bluetooth devices, such as a smartwatch or other Bluetooth headset that is not enabled. Try disconnecting other devices or turning them off to see if the problem goes away.

6. Update the firmware. When some Bluetooth headsets experience sound problems, downloading the official app and updating the firmware can fix all the problems. Check to see if the Bluetooth headset you are using offers an affiliated mobile app.

7. Turn off any audio processing. If there are apps that use Bluetooth headsets, try turning off their additional features such as equalizers, noise reduction effects, and other features that may cause distortion or other anomalies in the sound. If the phone has built-in audio features (such as Samsung's Adapt Sound feature), turn them off as well.

8. Adjust the Bluetooth audio transcoder. In the Bluetooth settings of your playback device, tap "i" or the settings cog next to the headset to see what Bluetooth audio transcoders are available (some phones do not have this feature). Some Bluetooth headsets offer HD Audio or other similar HD transcoders that can be turned on or off to see if the sound improves.

9. Switch off your Windows PC's hands-free mode. When a Bluetooth headset is attached to a PC, the Windows sound settings may show two inputs, one for stereo music and one for phone calls. Select the speaker icon in the lower right corner, then select the audio source from the list, making sure to select Headset rather than hands-free. (This can be disabled by navigating to Console > Hardware and Sound > Devices and Printers, right-clicking on the selected Bluetooth headset, and selecting Properties. Uncheck Hold-Free Phone under Service Settings.)
