Loop it. Palm it. Now we can carry our sound our way with the new Pushlock interchangeable accessory system. All that power at the push of a button - Wrist strap and carabiner included in the box.· Why is there no USB-C charging cable included with my product? To minimize e-waste, we consciously choose not to include a charging cable in our packaging. However, you can use any standard USB-C cable to charge your JBL product.
