Pioneer's history in quality audio equipment began 80 years ago, with the vision of 'delivering the joy of music to people far and wide'. In 1937, we produced the A-8, the first dynamic speaker to be produced in Japan, and we have been committed to high fidelity sound reproduction ever since. Whether we are making home speakers, car speakers or headphones, our focus is always on the pure, faithful reproduction of sound. We have been developing and producing ground-breaking headphones for more than half a century, starting with the SE-1 headphones in 1960. Now we're writing the next chapter in our long history of technical supremacy and purity in sound design.
