Using your Koss Porta Pro 2.0 Wireless Bluetooth Headphones is easy. First, if you want to use them wirelessly, turn on the headphones using the power button on the side. Pair them with your device via Bluetooth. If you prefer a wired connection, just plug in the provided USB - C to 3.5mm cord. To control playback, use the on - board buttons for play, pause, volume, and track switching. When it's time to charge, connect the USB - C charging cord. For the best performance, keep the headphones away from extreme heat or cold. Clean the ear cushions regularly with a soft, dry cloth. Don't use harsh chemicals as they might damage the foam. When not in use, fold them up and store them in the carrying case to protect them from scratches and dust.
