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-B, 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, our speakers or headphones, our focus is always on the pure, faithful reproduction of sounds.

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.

THE FLAGSHIP SE-MASTER1 CONTINUES OUR LEGACY. WELCOME TO THE FUTURE OF SOUND REPRODUCTION.

MONITOR REFERENCE

SE-MASTER1

Approved AIR Studios Monitor Reference Headphones

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

PUTTING THE SE-MASTER1 TO THE TEST WITH AIR STUDIOS

AIR Studios's technical director Tim Vira-Lott was integral in the tuning of the 50-MASILTVs. Tim's discerning ears helped us to compare the headshones to premium reference speaker systems and identify the adjustment needed to ensure the headphones delivered the same sound quality. This process of line-tuning was repeated until, the headphones met AIR Studios high standards, delivering faithful reproduction of all sound sources from this reason to the most subtle nights to the deepest base.

AIR Studios was established in 1962 by world famous producer Sir George Martin. Since them has earned a reputation as the world's most recording source, earning the trust of many world famous artists.

TIM VINE-LOTT

AIR Studios Technical Director

I've tuned many audio products in the past, but tuning the SL-MASIL. It was an interesting and challenging experience, completely different to working with amplifiers and speakers. Headphones have none of the adjustable electric circle you'd find an amplicator or speaker systems, and the smallest change could have unexpected effects on sound quality - e.g. it was slightly altered the size of the hole controlling the backpressure of the driver units. But working with Pioneer's engineers, we were able to achieve the best sound quality. I really hope everyone will enjoy the wander in sound of the SL-MASIL FRT.

As technical director at AIR Studios, Jim Vine-I still has been involved in producing countless albums for artists and soundtracks for films. Responsible for granting AIR Studio Certification to audiovisual products that pass strict standards, he works with Pioneer in tuning our amplicators, speakers and now headphones.
