Found black JBL speaker near Castillo de San Marcos

I found a black JBL speaker this afternoon around 2:15 pm on the Castillo de San Marcos promenade, tucked behind a bench near the brick path by the water. It's about the size of a forearm, with a fabric grille and a small dent along the rim. A short bright blue charging cable is still plugged into it, and there's a faint coffee stain along the edge. Otherwise it's in decent condition, no cracks or obvious damage. If anyone recognizes this, please ping me and I’ll help reunite it with its owner.
