Are all Sennheiser products supported by the Smart Control App?

Yes, you can browse on the discover page and get latest news from Sennheiser or check the user account where you check sign in for the newsletter. But, of course there are much more configurations options with Sennheiser products.\n

Can I use the app without having a Sennheiser product?

There could be several reasons for it. Please check following:

- Ensure the product is nearby and turned on
- Make sure Bluetooth is turned on your smartphone
- Only on iOS: App will ask you by the first launch to allow the app access Bluetooth.
- Check in the smartphones settings if this permission is in place.

- If you were already connected with this product and removed it from the device list, ensure you removed all product items also from the Bluetooth menu of your smartphone. Otherwise app will not be able to connect this product again.

- Only Android: Smart Control uses BLE scan to find your product. Android requires location access in order to run BLE scan. Please make sure app has permission to access location in order to scan for new products. Once your product is found by the app and connected once, you can switch location access again. Smart Control app will not collect or track your location for any other reasons, except you use the Sound Zones features where location access is required.

- If you want to connect a Soundbar, enable access to local network.\n

Why doesn't the Smart Control App find my device?

\nTry to turn the product off and on to restart the app. If it still doesn’t work remove the product from the device list (use the dot menu on the top right corner) and remove Bluetooth item of the product from the Bluetooth menu of your smartphone. Restart the app and try to scan for new products and to connect.
If connection to a Soundbar cannot be established, follow instruction in the app in order to set up the Wifi connection.\n

I can see my product on the device page, but connection cannot be established. What can I do?

\nYou can easily update your product with the Smart Control app. Once new firmware update is available you will be notified about it in the app. If you signed in for the push notifications, you will receive the notification even the app isn’t active.
Please follow instruction in the app in order to update your product. Depending on the size of the firmware package and your smartphone update can take from 2 to 60 min. Smart Control will inform you about estimated update time, so you can decide to update now or later.
If the firmware tile on the setting page is showing your product is up to date, there is no new firmware package available for your product.\n

How can I update my device?

\nPlease check your internet connection (Wifi or mobile network), make sure Smart Control is allowed to use mobile network if not connected to Wifi. Restart Smart Control app and wait a couple of minutes. Contact our service team in case it still not work.\n

I know there is a firmware update available for my device, but the app keeps saying “your product is up to date”. What can I do?

\nNo, depending on the product there can be different feature set available in the app.\n

Do all products have same feature set?

\nYes, with version 4.0.0 you can configure the product page and remove feature tiles from the main product page. All features will be placed to the setting page.\n

The product page is overloaded, I just want to have 2 feature tiles on my product page. Can I configure it?

\n1. Please go to the Bluetooth settings of your smartphone and click "Forget This Device" (refers to your Soundbars Bluetooth name). Retry searching for your Soundbar again.
2. If you still don't see the Soundbar, please reset the App via app settings and search for the device again.\n

I open the Smart Control App, but the App doesn't find the Soundbar.

\n- If your Soundbar appears in the device list with the state "Not found on WiFi scan", please scan for devices again. If this does not help either, please turn off your phone's WiFi and turn it on again.
- The Soundbar and your smartphone are connected to different networks. Please connect your smartphone to the same network the Soundbar has been connected to and scan for new devices again.
- Your Soundbar is connected to a guest network which does not allow device communication. Please reset your Soundbar with the reset button on the rear side and set up the Soundbar with another network.\n

After setup, I see the Soundbar in App, but it states "not found on WiFi scan."
