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.
Reboot the connected device.
Electronics might need to be reset from time-to-time—much like rebooting a computer. Power off the device, then power it back on and try again.
Try connecting the headset to a different device.
If the headset works with one device but not another (with or without an adapter), there may be an issue with that particular device.
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.
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.
