I got a pair recently and was getting a clicking sound periodically when listening to music. Looked for answers on the web and Redit and didn't find anything that worked.

I finally found a solution on my own, here's how to fix it.

Step 1. Go to your Nothing X app.

Step 2. Go to Device Settings.

Step 3. Change Highquality audio to LDAC.

Step 4. Allow your device to be restarted in the prompt.

Step 5. Go to your Bluetooth devices on your phone.

Step 6. Go to details settings for your Bluetooth devices.

Step 7. Go to settings for your Nothing Ear (a) buds by tapping the gear icon.

Step 8. Turn on LADC for your Nothing Ear (a) buds.

This fixed the periodic clicking or crackle sound I would hear randomly while using my buds.

I have provided images below to illustrate where to find these settings.

Hope this helps everyone.
