Common questions about manuals, registration, and support for this brand.
Turn on the speaker; it usually defaults to Bluetooth mode (indicated by a flashing light). On your mobile device, search for the pairing name (e.g., 'SOONBOX-S3900' or 'S9500') and select it to connect.
Turn on two identical SOONBOX speakers. Long press the specific TWS or Mode button on one unit (refer to your specific model's manual) to initiate pairing. A tone or light change typically confirms the connection.
SOONBOX speakers include a power-saving function that automatically powers off the device after 10 to 15 minutes of inactivity. It may also shut down if the battery voltage is too low.
Insert the Type-C charging cable to act as an antenna (do not connect to power). Switch the mode to FM using the Mode button, then single-click the Play/Pause button to scan for stations.
Generally, a red light turns on while the speaker is charging and turns off once the battery is fully charged.
