Bluetooth disconnects from paired device

If the Bluetooth connection between your system and a connected device (e.g. 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.

Reboot the Bluetooth® device.

Electronics, such as cell phones, tablets or computers, might need to be reset on occasion to correct minor issues. This is typically done by turning the device off, 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 information, 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, including any duplicate listings labeled LE (Low Energy), then reconnect it to the device. For more information, 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.

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.

Try connecting a different Bluetooth® device.

If your Bose product can connect to another device, Bluetooth functionality is working. In cases like this, the issue could be with 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.
