For consistent playback quality, keep the speaker within Bluetooth range of the source device and maintain a clear line of sight where possible. Use AC power for extended listening sessions to avoid battery depletion; switch to battery power when moving the speaker between rooms. Clean fabric and aluminium surfaces with a soft, dry cloth and avoid exposure to moisture.
