These water resistant nylon amplified stereo speakers attach to your bike handlebars or frame with velcro-like straps and allow for a safer biking experience by eliminating the use of earbuds. The water resistant zippered storage compartment has a removable eyeglass case and a pouch to hold your MP3 player, iPod, or iPhone while using the 3.5mm connecting plug or the lightning plug adapter for iPhone 5-10X. Easy-to-use controls on the face of the speakers let you turn the unit on and off and adjust the volume. Though designed for biking, you can also attach the speakers to your stroller, sports equipment or use them at the beach or pool or on your desk. Available in black with gray zipper. Operated on four AAA batteries (not included). Gift boxed.
