Bluetooth® disconnects from paired device

If the Bluetooth connection between your system and a connected device (i.e. laptop, smartphone, or Bose app) is intermittent or is lost unexpectedly, try the following:

If your headset is charging, disconnect it from the charger.

While the headset is charging, Bluetooth® is disabled. Charge the headset as needed, then disconnect the charging cable to connect a Bluetooth device.

Be sure your product is within 33 feet (10 meters) of the Bluetooth® device.

Bluetooth range is about 33' (10 m). This range can be reduced by obstacles (i.e. walls, doors, pockets, nearby Bluetooth devices, etc.). Try moving the device and product closer together.

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.

Reboot the Bluetooth® device.

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

Clear your Bose product memory of previously-connected Bluetooth® devices.

Your Bose product remembers the last several devices it connected to so it can quickly reconnect to them. In case there is an issue with the device memory, clear it and then try to reconnect the 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.

If connected to a Windows computer, check the power management setting for the Bluetooth® adapter.

  1. On the computer, click the Start menu and begin typing device manager
  2. Click Device Manager in the search results to open it
  3. Click the > next to Bluetooth to expand it
  4. Right-click your Bluetooth adapter and select Properties
  5. Click the Power Management tab and uncheck Allow the computer to turn off this device to save power
  6. Restart your computer and try again.

If using your product outdoors, check for differences when used indoors.

Since there are fewer boundaries and reflective surfaces outdoors, Bluetooth® signal might not reach as far. Check if the product functions better indoors to determine if the environment is the issue.

Determine if the issue occurs with another Bluetooth® device.

Try pairing your Bose product to a different device to determine if the issue is related to the first device or its settings.

Connect a different Bluetooth® device.

Try another Bluetooth device to determine if the issue is related to the first device or its settings.
