Whether you clip it, hold it, or pack it, the SoundLink Flex Portable Bluetooth Speaker from Bose makes it easy to take and enjoy your favorite music anywhere. The Flex is small enough to hold in your hand or store in a bag, or you can use the built-in nylon sport utility strap and an optional carabiner to clip it to a backpack strap. It’s possible to take the Flex anywhere, thanks to its silicone-wrapped body and robust construction that makes it dustproof, waterproof, and resistant to drops, shock, crushing, and rust.
