Humming, buzzing or rattling noise heard from product | QuietComfort® 20 Acoustic Noise Cancelling® headphones— Samsung devices
If you hear an unexpected noise from your product:
Try the following:
Make sure the connected device is grounded.
When connected to or charging from an ungrounded device, such as a computer or TV or USB wall charger, it is possible for the headset to produce a humming sound. If possible, disconnect the device from power to eliminate this noise when listening, or find a grounded power outlet.
Unplug and reconnect the audio cable in the connected device.
On the connected device, disconnect the cable that connects your headset. Then, reconnect it to be sure it is fully connected and secure. (Tip: While connected, if you rotate the plug in the jack and hear crackling or intermittent sound, there might be debris or an issue with a contact inside the jack.)
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.
Try connecting a different audio device.
If available, connect another audio device using the same cables and connections to determine if the issue is related to the first device or its settings.
Plug in a different pair of headphones.
Connect another pair of headphones to the audio device to determine if the issue is with the device or its settings.
