No audio from product

If your product seems to be set up properly but does not produce sound, try the following:

On the audio cable, try changing the Hi/Lo switch position.

The Hi/Lo switch on the audio cable connector is useful if audio is too loud or too quiet in the headset, even after adjusting volume. Be sure it is set properly. For more info, see Setting the audio attenuation Hi/Lo switch.

Check the volume level on the source.

Its possible the volume is too low or muted. Increase the volume gradually

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.

See if the light is lit on the right earcup.

To produce sound and cancel noise, they headset must be powered on. Flip the switch on the right earcup to the on position: If the green light does not turn on, see No power.

Check the condition of the headphone cable.

If the plug or any part of the cable for your headphones is damaged, you can replace the cable.

Remove and reseat the input cable at both ends.

For the best sound quality the input cable must be securely connected at both ends. This may require an extra amount of pressure to properly seat the cable into the earcup. Carefully, but firmly, press the connector into its socket at the earcup until a slight click is felt.

Try a different audio cable.

Two audio cables were included with your headphones. Connect your headphones to the same audio device with both cables to determine if the issue is one of the cables.

Try a different app.

If the issue only occurs with a particular app, it is likely related to the app or app settings.

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.

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.
