Due to continuous use, the headphones get overheated, the same can happen with your device. So, stop using your headphones and let them cool down.

Too much distance between your headphones and a connected device like laptops, smartphones can also cause a muffled voice.

Because Bluetooth functions well within 30 feet range. So, make sure that both devices are placed closer to each other.

If you are using a cable for connecting your headphones, make sure the cable is functioning. Also, confirm that the wire is connected firmly.

Always use a compatible cable that is provided with your headphones instead of a cheap and third-party product.

The audio connection port on your headphones should be in good condition-not broken or loose.

Headphones Sound Muffled: Causes and Solutions

In this section, we will describe the common causes of the muffled sound and will also suggest you the best solutions.

1. Weak Connection

Since the headphones are wireless, they are likely to get muffled due to a weak connection.

For example, you have connected your headphones to your smartphone via Bluetooth and you are listening to calls or music.

If the Bluetooth connection is weak, the sound will come muffled. In addition, there may be a compatibility issue; the Bluetooth version is older.

The Bluetooth 4.2 or 5 is considered ideal for headphones. Further, if you are playing music live on your device, a bad internet connection can also cause a muffled sound.

In case of making or receiving calls, the weak phone network can also cause a muffled sound.

Solution

One handy solution for this problem is to disconnect your headphones from the device. Reboot your device and connect the headphones again.

Another trick is to restart your mobile or computer. Workload, temporary bugs, and caches can cause a muffled voice.

If the battery is low, charge it fully and then reconnect. Change your position and orientation, this will help solve the weak connection issue.

Make sure your internet connection is strong. A temporary issue can be solved by disconnecting and reconnecting the headphones with the Wifi.

2. Trapped Dirt or Debris

You use headphones both indoor and outdoor. So, they are likely to accumulate dust in speakers and ports. Over time, the dust gets hard and clogged into the openings.

So, it causes muffled sound through your headphones. Because the air has to pass through the small gate of the dirt and some of it is lost on the way.

Earwax can also trap inside the audio ports and gives muffled sound.

Solution

Even if you cannot see dirt in the ports of your headphones, still you should clean them thoroughly.

One common method is to suck your earbuds, it will remove the earwax and dirt. It may sound odd, but this method worked well for many users.

Alternately, you can use cotton buds, move them gently around the cup area and speaker.

Another method is to blow the dirt out using a compressed air can. Take a paper clip and straighten it by unfolding it. Tightly, wrap the sticky tap at one end of the paper clip.

Now, insert this combo into the audio jack and other small openings on your headphones. The tiny dust particles will stick to the tap, change it once it gets dirty.

3. Liquid Damage

Sometimes, water or moisture enters your headphones and damages them. This can be caused due to careless handling.

For example, using the headphones with wet hands, wearing them during the shower or while your hair is wet, walking in rain, or spilling some liquid accidentally.

But, maybe your headphones are water-resistant as most of them are. But, it does not mean you can freely use them in water.

You have to check the IP rating of your headphones; some are only splash and moisture-proof. Water can harm the speakers of your headphones as well as corrode metallic components.

Solution

If you are sure that your headphones have contacted water then try to dry them out.

Take a cotton pad and dip it into the 91% isopropyl. Remember you have to make the cotton a little wet, it should not be dripping liquid.

Now, rub this pad onto the parts of your headphones that are wet or rusty.

Next, take a big-sized airtight jar and fill it with silica gel. Leave your headphones in this jar for 12 hours so that they can dry completely.

If you do not find the silica gel, you can use rice. But, this method may have side effects as your headphones can capture the dust from rice.

4. Incompatible Audio Format

Another common reason for muffled headphones is the incompatible audio format. A low-quality audio format results in a sound loss.

For instance, low-bitrate MP3 files are unable to output the file data. Hence, the sound reaching your headphones is muffled.

Solution

The sole solution to this problem is using high-quality audio sources. Whenever, you play a track on your phone or PC, make sure that it has a compatible format.

You can check the source issue by playing multiple audio files. If only a few are muffled then your headphones are working well and the problem is in particular audio files.

5. Software Issues in the Devices

Certain software issues in your headphones, computer, or phone can also cause a muffled sound. For example, pending software updates, glitches or bugs interfere with the sound quality.

Solution

You need to reset your headphones and clear the Bluetooth pairing list on them. The method differs across various headphones models and brands.

You can check the reset method in the user guide or online. Another solution is to install the software update on your phone or PC to which your headphones are connected.

Also, check the audio drivers on your devices, they should be running the latest firmware.
