When it may not be suitable

The feature set focuses on convenience and portability rather than high-end audiophile performance or professional sound reinforcement.

How to use

Charge the built-in battery using the supplied charging cable until the indicator shows full charge. For wireless playback, pair a Bluetooth-enabled device by enabling Bluetooth on both devices and selecting the speaker from the device list. To use FM radio, switch the unit to radio mode and tune to the desired station. Insert a compatible USB flash drive into the USB port to play stored audio files directly. Connect a karaoke microphone to the dedicated mic input for live vocals; adjust the volume and microphone level using the unit controls. Refer to the included user manual for details on button functions and charging times.

What to consider before purchase

• Intended use: suitable for personal and small-group events, not for large professional venues
• Battery runtime expectations: actual playback time depends on volume level and playback mode
• Connectivity needs: Bluetooth and USB covered; check if auxiliary or other inputs are required for your setup
• Portability versus sound demands: compact size favors transportability over high-volume output

Usage recommendations

For extended outdoor use, keep the speaker charged and carry a power bank if you expect long playback sessions. Place the speaker elevated and unobstructed for better sound dispersion, and lower microphone gain if feedback occurs during karaoke. Use USB playback for offline playlists and Bluetooth for convenient streaming from mobile devices.
