If you are not able to turn Spatial Audio on and the option is greyed out on the JBL Smart Tx, then you need to do the following.

• Open the JBL Headphones app
• Disable High-Resolution Audio (LDAC)
• The headphones will turn off and reboot
• You can enable Spatial Audio after the reboot

If your teammates can not hear you, make sure of the following:

To have the best Active Noise Canceling performance possible, we advise you to keep the earbuds clean as much as possible. In case the IR sensors are covered with dirt of any kind, the Active Noise Cancellation performance will not be as effective. Sometimes, it may not give you the desire outcome to enjoy your music. 

Make sure both headphones are fully charged to ensure that the issue is not due to one of the earbuds lacking power.

Check that the contact points on the headphones and the charging case are clear of dirt, so the issue is not due to the product not being able to charge.

The LED on the headphones will show a blue light when correctly inserted in the charging case.

Try to reset the headphones if the product is fully charged but are still only working in Mono mode.

A reset guide for the headphones can be found here: Reset guide

1. Your Citation device is turned on
2. Check the password you have entered, and re-enter it again (typos can happen).
3. Make sure your mobile device has the initial support needed:
   1. Android 4.4 OS and higher
   2. Apple iOS 10 OS and higher
   3. The latest version of Google Home app
4. Your phone needs Bluetooth to be on 
5. Enable Location Service (Android only)
6. Plus you need to permit Google Home app to access your location on the phone (Android only).

The basic check is done, and we are now moving into your Wireless network setup.

1. Try moving your speaker closer to the Wireless network router 
2. Have you previously connected the speaker to your WiFi network?  If yes, look below or move to "Troubleshooting"
   1. Did you recently make any changes to your network, such as buying a new router, adding an extender, or maybe changed settings?

   2. Maybe your ISP (Internet Service Provider) did some changes, possibly even updating your Wireless router software.

Troubleshooting

1. Your WiFi router might need a reboot, unplug power for 1 minute and connect power again.
   1. While you are rebooting your WiFi router, we advise doing the same for your speaker. Simply disconnect power and reconnect power again.
   2. In case rebooting the speaker didn't work, let's try resetting your speaker by pressing the Reset Button for 5 seconds (Front LED will light up).
2. Go ahead with the setup again (remember to open Google Home app )
3. Reboot your mobile device

WiFi Network Troubleshooting

• Check your WiFi router settings. Be sure that UPnP (Universal Plug and Play) is enabled.
• Change Wireless channels on your WiFi router on 2.4G or 5G..
  • Avoid using other channels on 2.4G other than 1, 6 and 11. The rest are a NO-GO.
  • Keep a maximum of 8 devices in total on 2.4G (that is including our speakers).
  • Move products to WiFi 5G band, if they support it, to reduce the stress factor on the 2.4G band
• Check your WiFi router to see if there is a MAC address limitation.
  • MAC address limitation is when your router is set/fixed to a maximum of 20 devices (or whatever it may have been configured for).
  • When you want to add the 21st device your router will deny access because you have filled up the 20 devices.
  • You need to clear or delete old devices that are not in use anymore. This may require someone with technical knowledge.
  • We advise that you don't have any MAC address limitations at all.
• Avoid bad extenders (Cheap ones are often not powerful enough to deal with or handle the kind of data required to transmit high quality audio).
  • With extenders, the connection between "router and extender" is decreased by 50%.  That said, your data will be even slower,. having to processes it while the speed is decreased.

10 minutes before the time limit has been reached, a voice prompt will be played on the headphones. When reaching the time limit, the volume will be muted, and a new voice prompt will inform that the listening limit has been reached.

Getting started with the checklist

• A JBL LINK device(s).
• Latest version of the Google Home app installed on your mobile device.
• Latest version of the Google app  (Android only) installed on your mobile device.
• A Google Account (you can create one online via Google).
• A mobile device with either iOS or Android support.
  • ​Must have iOS 10 or higher
  • Must have Android 5.0 and higher
  • There is no support for PC set up.
• An internet connection from your local ISP (Internet Service Provider).
• Your Wireless Network must secured with WPA2 Encryption (Enterprise mode NOT supported). 
• Availability and performance of certain features, services and applications are device- and network-dependent and may not be available in all areas; subscription(s) may be required, and additional terms, conditions and/or charges may apply.

Wi-Fi requirement

• Wi-Fi routers must have Encryption enabled to install JBL LINK speakers (WPA2 etc).
• Wi-Fi Extenders need to feature support of Multicast forwarding and UPnP.
• Always use 5 GHz Wi-Fi for best performance and less interference.
• For routers that have 2.4G Wi-Fi support only, make sure that they are using channels 1, 6 or 11 only.
