Check that the headphone jack is clean and free of debris.
Use a flashlight or other light source to check if any lint or debris has entered the headphone jack on the device, which can interfere with the connection.
Be sure the buttons on your product are not stuck.
When you push a button on your product, you should feel it depress. When you release the button, it should snap back to its original position. If it does not, it may be stuck. Check for and clean any debris around the button.
Remove the connected device from any case or protective sleeve.
A case or sleeve may prevent the audio cable from seating properly into the headphone jack. If using a case, remove it and try again.
Remove and reseat the audio cable in the connected device.
On the connected device, disconnect the cable that connects to your headset then reconnect it to be sure it is fully connected and secure. If you rotate the plug in the jack and hear crackling or intermittent sound, there might be debris inside the jack or on the headphone plug.
If connected, bypass any adapters or extension cables.
If your product connects to the device using an extension cable or adapter, disconnect the extension cable or adapter to determine if the issue is related to it.
Make sure the device is compatible with the headset.
Some devices are not compatible. See
Compatibility Guide.
Check the condition of the headphone cable.
If the plug or any part of the cable is damaged, replace the headphone cable.
