Found small black portable Bluetooth speaker on the beach near Lido Key, Sarasota-Bradenton.

I found a small black portable Bluetooth speaker while walking on the beach near Lido Key in Sarasota-Bradenton. It looks like it has been there for a little while, as it was partly buried in the sand. It has no visible brand markings but has a rubberized exterior and pairs easily with devices. I would love to return it to its owner if they can describe it or provide any identifying features.
