109 Pro is a demonstration of our commitment to go beyond the faithful reproduction of sound to deliver pure emotion. It all started with a purpose – creating joy. It’s about letting yourself get lost in sound, about that intimate connection you have with your favorite artist, song or instrument when all distractions are removed.
