How to Fix Static Noise in Headphones? (Bluetooth & Wired)

Why Headphones Sound Staticy?

That static sound coming from your wired headphone is often caused by a faulty audio cord, a bad plug-in, or an outdated Noise Cancellation feature.

For Bluetooth headphones, the static sound is often caused by a bad Bluetooth connection, signal interference, bad amplifier, or faulty sound card in your PC.

To stop the static sound, you need to find the cause. On your Windows PC, run the Windows Audio troubleshooter to find the cause. Then update the audio device driver and replace the sound card to fix the problem.

On your smartphone, reconnect the devices, clean the audio jack port, or reset the headphones. You should also check the Bluetooth and Sound settings on your devices.

What Causes Static Noises in Headphones?

Things that cause static noises in headphones, are as follows.

1. Faulty Cables

A faulty cable will cause static noises in wired headphones. Inspect the wire to see if it’s broken, damaged, or cut and replace it if you can. Some headphones don’t allow wire replacement, so you must replace the headphones.

2. Bad Phone Case

A bad phone case can prevent a proper connection between the wired headphones and the phone. This can cause the wire to move and produce static sounds. The phone case shouldn’t cover the audio jack port. Try removing the phone case and check if the static sounds are gone.

3. Noise Cancellation Feature Is Outdated

An outdated noise cancellation feature can cause static (or similar) sounds in your headphones. Outdated noise-canceling technology might not be compatible with newer audio devices or software updates. This can lead to compatibility issues, connectivity issues, and static sounds.

Usually, the hissing (static sound) will stop once you play music if the issue is the noise-canceling feature.

Note: Wired headphones don’t have the best noise-cancellation feature.

4. You are Using a Bad Amplifier or DAC

A bad or low-quality amplifier or DAC can cause a hissing sound. DAC (Digital-to-Analog Converter) is an electronic device or circuit that converts digital audio signals into analog signals. If the DAC is low-quality, it will send low-quality audio signals to your device and cause static sounds.

Amplifiers can pick up electromagnetic interference from nearby electronic devices and cause static sounds. A bad or faulty amplifier, damaged wire (that connects the amplifier to the headphones), and improper grounding will cause static sounds.

5. Faulty PC

A faulty sound card in a PC can produce static sounds. The sound card processes and converts digital audio signals into analog signals that can be played through headphones. If the sound card is faulty or damaged, it can introduce different audio issues, including static or crackling noises.

To fix this, install the latest driver for your sound card.

6. A Third-Party App is Causing The Noise

A third-party application, such as Spotify or Youtube, can cause static sound. It’s recommended to change the music application to troubleshoot the issue.

7. Bad Bluetooth Connection

Out-of-range Bluetooth connection, interference, or a signal jammer can cause static sounds. It’s recommended to keep both devices within the Bluetooth range (10 meters or 30 feet) and avoid Bluetooth interference.

How To Fix Static Sound on Headphones for iPhone/Android?

To fix static sound on headphones for iPhone or Android, do the following.

1. Re-connect Bluetooth

Restarting or re-connecting Bluetooth can fix (or bypass) software issues that are causing static sounds.

To re-connect or restart Bluetooth, do the following.

  1. Go to Settings and locate Bluetooth Settings. On some devices, Bluetooth settings are located under Wireless Connections.
  2. Find the list of Paired Devices, find your “Headphones’ name”, and press the ““. Then select Forget or Remove Device.
  3. Turn off the Bluetooth on both devices for a few seconds and turn it back on.
  4. Put your headphones on Pairing Mode and pair them to your phone.

2. Clean The Audio Jack Port

A dirty Audio Jack Port can lead to compatibility issues, connectivity issues, and static sounds. This is because the dirt will prevent proper contact between the Audio Jack Connector and Audio Jack Port.

To clean the Audio Jack Port, use Q-tips, a cotton swab with rubbing alcohol, or blow air inside it. Dip the Q-tip or cotton swab into rubbing alcohol, and use it to clean the inside of the port.

You can also rotate the headphones jack or push it inside more to see if that fixes the problem.

3. Avoid Bluetooth Interference

Bluetooth interference from nearby devices can cause static sounds and different connectivity issues. Bluetooth interference refers to the disruption or degradation of Bluetooth wireless communication caused by external factors or other devices operating on similar frequencies (2.4 GHz).

Move the headphones away from the devices or causes of Bluetooth interference.

Here are common causes of Bluetooth interference:

  1. Other wireless devices.
  2. Physical objects.
  3. Radio frequency interference.
  4. Crowded wireless environment.
  5. Electrical interference.

4. Close Other Apps

Running multiple apps on your device, especially audio apps can cause different sounds. One app very common for causing this is radio so ensure you aren’t running multiple audio-playing apps on your phone.

5. Check Audio Settings

Check the sound and audio settings on your device. Is the equalizer enabled? Check the sound balance settings too. You can switch between different audio settings to see if any stops the hissing sound.
