No audio from product

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

Bluetooth® operation is disabled while charging.

The headset begins charging when connected to a charger or powered USB jack. While charging, Bluetooth functionality is disabled. To play audio from and/or pair Bluetooth devices, disconnect the headset from the charger once it is sufficiently charged.

Alternatively, you can listen to audio while charging the headset by using the supplied backup audio cable.

Confirm the headset is connected to the Bluetooth® device.

Power on the headset, then press any button to view the Bluetooth and battery lights. If the Bluetooth light is flashing or not lit, the headset is not connected. Try reconnecting the headset in the Bluetooth settings of the device. If is still doesn't connect, see Cannot connect a Bluetooth® device.

Reboot the Bluetooth® device.

Electronics might need to be reset on occasion to correct minor issues. This is typically done by shutting down the device, then powering it on again.

If adding a device to Windows 10, be sure to connect to the Bluetooth® device with the headset or speaker icon.

In Windows 10, your product shows up twice in the Bluetooth device list: once with a device icon and LE before the product name and once with a headphones or speaker icon. Select the option with the headphones or speaker icon. Do not select the LE listing.

Tip: If you already paired to the device icon, just connect your product again and choose the listing with the headphones or speaker icon. For more info, see Connecting a Bluetooth® device.

Windows 10 Add a device screen

Try connecting the device with the included audio cable.

Note: When the audio cable is connected to the headphones, Bluetooth® functionality is disabled.
  1. Connect the smaller end of the audio cable to the jack at the bottom of the left earcup
  2. Plug in the other end of the cable to the 1/8" (3.5 mm) headphone jack on your device.

Try a different app.

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

Determine if the issue occurs with another Bluetooth® device.

The source device currently paired to your product may be causing the issue. Try pairing a different Bluetooth source to see if the issue is isolated to that device.

Clear your product's memory of previously paired Bluetooth® devices, then reconnect.

Your product remembers the last several devices it connected to so it can quickly reconnect to them. In case of an issue with the device memory, clear it, then reconnect your device. For more info, see Clearing the product memory of paired Bluetooth® devices and Connecting a Bluetooth® device.

Remove your product from the memory of the Bluetooth® device, then try again.

In the Bluetooth settings of the Bluetooth device, find the list of previously connected products. Remove your product from the list, then reconnect it to the device. For more info, see Connecting a Bluetooth® device.

Reset your product.

Much like rebooting a smartphone, your product might need to be reset on occasion to correct minor issues. For more info, see Resetting your product.
