Usage recommendations

Place the speaker on a flat, stable surface for optimal sound projection and avoid covering vents or drivers. Use high-quality audio files (FLAC or APE) on the MicroSD card for improved clarity. For prolonged listening sessions, monitor battery or power status and use a compatible USB Type-C charger when required.
