This Bluetooth Speaker from Braven has been one of my favorites. It's not a new one, but it's still a great speaker. It's a ruggedized speaker that can handle drops, water, anything you through at it, basically. It's made to go to the beach, or to a construction site. Which is why it's not the most amazing looking speaker out there, but it does its job, and does it well. With great audio that can play for around 10 hours before needing to be recharged.
