If your headphones are playing muffled sounds and drowning out voices, there are a few potential causes and troubleshooting steps you can try:
Audio settings: Check the audio settings on your device. It's possible that the audio balance is skewed towards certain frequencies, making voices harder to hear. Adjust the equalizer settings or audio presets to see if it improves the clarity of voices.
Physical obstruction: Inspect your headphones for any physical obstructions, such as debris or dirt in the ear cups or on the driver units. Clean them gently using a soft, dry cloth or a small brush to remove any blockages that might be affecting the sound quality.
Loose connections: Ensure that all connections are secure. If you're using wired headphones, check that the audio jack is fully inserted into the device's audio output. For wireless headphones, make sure the Bluetooth connection is stable.
Audio source issues: Test your headphones with different audio sources, such as a different device or media player, to determine if the problem lies with the headphones or the source. If the issue persists across multiple devices, it's more likely a problem with the headphones themselves.
Driver or speaker damage: It's possible that the drivers or speakers in your headphones have sustained damage, which can result in muffled sounds. If the headphones have been dropped or subjected to physical stress, it may have affected the internal components. In such cases, professional repair or replacement may be necessary.
If none of these troubleshooting steps resolve the issue, it would be advisable to contact the manufacturer's customer support for further assistance. They can provide specific guidance or initiate a warranty claim if applicable.
