Sure, this wireless Bluetooth speaker can be used anywhere—outdoors or inside. It is specially made to cut through the wind and other environmental challenges. The Turtlebox Bluetooth speaker is relatively compact and, despite its $300 plus price, is a tremendous value compared with other similar speakers. Its sound is its primary draw, but as a side benefit, it's completely waterproof to survive the elements and can also charge other devices from an on-board USB-C port.
