State of the art headphones for studio level sound reproduction

Delivering the exhilaration of music to the world. One vision at the heart of our history in sound.

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 are writing the next chapter in our long history of technical supremacy and purity in sound design.

The flagship se-master1 continues our legacy. Welcome to the future of sound reproduction.

Made in Japan - handcrafted by a master

Meticulous attention to even the finest detail was given to the production of the SE-MASTER1. Each unit is assembled by a master craftsman at the Tohoku Pioneer Plant in Japan; the birthplace of many iconic speaker models. We pour our advanced technological know-how into every step of the journey-from design to production and quality control- so your headphones deliver excellence without compromise.

Air studio approved monitor reference headphones

AIR Studios in London is world-famous for its matchless music production facilities and is the recording studio of choice for many iconic artists. The SE-MASTER1s are the first headphones ever to be named AIR Studios Monitor Reference Headphones, a rare honor that we wear with pride.

Industry's first membrane with ceramic coating

The lightweight 25μ-thick aluminium membrane is treated with a ceramic coating to give the headphones strength, to increase its natural performance and to ensure excellent sound quality. The result is high-definition sound across the entire frequency range.
