1. Check if the left earbud has power

The first step in troubleshooting your ATH-SQ1TW left earbud is to check if it has power. Sometimes, the earbud might not turn on due to a drained battery or other issues.

To check the power, simply place the earbud in the charging case and see if the LED indicator lights up.

If it does, then the earbud has power, and the issue might lie elsewhere. If not, try charging the earbud for a while and then check again.

2. Clean the left earbud

Dirt and debris can accumulate on the earbud, causing it to malfunction. To clean the left earbud, gently wipe it with a soft, dry cloth.

Avoid using any liquids or cleaning agents, as they may damage the earbud. Pay close attention to the speaker grill and the charging contacts, as these areas are prone to buildup. Once cleaned, try using the earbud again to see if the issue persists.

3. Ensure Proper Connection

Sometimes, the left earbud may not work due to a poor connection. Make sure that the earbud is properly seated in your ear and that the ear tips are securely attached.

Additionally, check the Bluetooth connection on your device to ensure that it is paired correctly with the earbuds.

If the connection seems weak or unstable, try moving closer to your device or removing any obstacles that may be blocking the signal.

4. Perform a Reset

Performing a reset can resolve issues like the left earbud not working by clearing any software glitches or connection errors.

It essentially restores the earbuds to their default settings, potentially fixing any underlying issues causing the problem.

To perform a reset on the ATH-SQ1TW earbuds:

  • Place both earbuds in the charging case and close the lid.
  • Hold down the button on the charging case for about 20 seconds until the LED indicator flashes rapidly.
  • Open the charging case and remove the earbuds.
  • Reconnect the earbuds to your device by pairing them again via Bluetooth.

5. Update the firmware

Firmware updates can sometimes fix bugs and improve the performance of your earbuds. Check if there are any available firmware updates for your ATH-SQ1TW earbuds and follow the manufacturer’s instructions to install them.

This process usually involves connecting the earbuds to a computer or mobile device and using a dedicated app to download and install the update. After updating the firmware, test the left earbud to see if the issue has been resolved.

6. Play audio from another device

To rule out device-specific issues, try playing audio from another device with your ATH-SQ1TW earbuds. This will help determine if the problem lies with your primary device or the earbuds themselves.

Connect the earbuds to a different device and play some audio to see if the left earbud works properly. If it does, then the issue may be with your original device’s settings or Bluetooth connection.

Pay attention to the charging contacts and the area around the speaker grill, as these are common areas for damage to occur.

If you notice any damage, contact the manufacturer for further assistance or consider getting a replacement earbud if the damage is severe.

If all else fails, reaching out to Audio-Technica’s customer support is a wise step. Explain the issue, your efforts to troubleshoot, and any relevant information.

They can provide further guidance, potential solutions, or information on warranty options. Customer support is there to assist in resolving more complex issues that users may encounter.
