How to connect the BOOST Luna 50 amplified speaker via Bluetooth?
Frequently Asked Questions - 31/12/2025
Response Notice-Facile

To connect your BOOST Luna 50 amplified speaker via Bluetooth, you first need to set the speaker to Bluetooth mode. Press the MODE button located on the top panel of the speaker, or use the MODE button on the remote control (button 3), until BT appears on the screen. The speaker will then automatically enter Bluetooth pairing mode.

Next, position your device (smartphone, tablet, or computer) within 10 meters of the Luna 50 speaker, and then enable the Bluetooth function in its settings. Search for available Bluetooth devices and select BOOST-LUNA50 from the list of detected devices. Pairing will occur automatically without requiring a security code.

Once the connection is established, you can control music playback directly from your device or use the provided remote control. Briefly press the PLAY/PAUSE button (button 10 on the remote) to start or stop the music, and use the navigation buttons (buttons 11 and 2 for next/previous track) to browse your titles. You can also adjust the main volume with button 9 located on the speaker panel or button 19 on the remote control.

Important points: ensure that the speaker is not in standby mode (waiting via the remote), as the internal battery does not charge in this state. If you do not change the input source for 30 minutes, the speaker will automatically switch to standby mode. If the Bluetooth connection is lost, restart the search on your device or press the MODE button on the speaker again.
