Multi-Function button on each ear-bud will play, pause, volume adjust, answer/end calls, and activate Siri or Google Assistant for convenience. These ear-buds have an IP54 waterproof rating to help protect them when you are out in the rain, working out in the gym and are perfect for sports and exercise.
