Listen to music during any activity with the Zulu Audio Wearable Bluetooth Speakers. Designed for use on the move, these speakers use strong magnets to lock onto your clothing. Patented magnet-to-speaker technology ensures the speakers stay on your shirt or jacket, allowing you to enjoy music or take calls anytime. A thin, lightweight magnet goes under your clothing while the other magnet in the speaker goes on the outside. The two magnets hold the speakers in place on your apparel regardless of what you’re doing. The magnets are actually so strong that you can even wear them while skydiving. The Zulu speakers also provide a safer way to listen since they don’t block out ambient sounds. Just place the speakers on your shoulders to send sound straight to your ears without disturbing the people around you. Finally, the bluetooth speakers offer four hours of battery life.
