JBL Wind 3 is a portable Bluetooth speaker designed for cycles, which includes two models: WIND3 and WIND3 Slim. Both are Bluetooth-enabled speakers, but the WIND3 supports additional playback options such as FM radio, AUX in, and TF/microSD media playback. You can choose the option that best suits your needs. Clipped onto your backpack shoulder strap, looped on a lanyard or tether, or docked onto your bicycle handlebars, JBL Wind 3 delivers sound wherever you go.
