To use a wired connection, insert a 3.5 mm cable into the AUX input.

Use the front panel controls or included remote (if provided) to adjust volume, change tracks, switch inputs and tune the FM radio.

Usage recommendations

Place the speaker on a stable surface and avoid blocking the front-facing drivers to maintain clear sound; keep the device away from moisture and extreme temperatures. Charge the battery regularly if the speaker is not used for extended periods to preserve battery health, and use appropriately encoded audio files for best playback compatibility from USB and Micro SD media.
