Each product in Alex’s portfolio has helped set the stage for the RAD-0 and all Rosson Audio Design products to come.



OUR CRAFT: RAD-0

Sound is essential to the human condition, it helps us explore the visceral depths of who we are and brings us closer through shared experiences. Inspired by the soundscape of our lives, Rosson Audio Design was born to breathe new life into one of the most fundamental elements of human existence.


At Rosson Audio Design, we prefer quality over quantity. By allowing our small team to leverage their unique expertise, we can confidently craft a headphone that is built to last, delivering a high fidelity sonic signature with exceptional aesthetics. Created by the hands of a craftsman, critiqued with the eye of an artisan, and tuned with the ear of an engineer, the RAD-0 delivers the accuracy demanded by professionals and the refinement craved by audiophiles.

 

The RAD-0 is born from years of R&D and a love for our craft. In order to create the best planar magnetic headphones on the market, our refusal to be rushed ensures that every component is inspected multiple times during its creation and assembly. Our team then thoroughly tests the final construction and preburns every unit for over 300 hours. All this is to say, let us worry about the gear, so you can indulge your obsession with music.



HOW WE MAKE THE MOST UNIQUE HEADPHONES ON THE PLANET

[ 66MM TRANSDUCER ]
Designed and manufactured at our lab in Reseda, California, the 66mm transducer lies at the heart of the RAD-0. With our use of a composite diaphragm material, unique circuit design, and array of 11 N52 neodymium magnets, the listener is able to enjoy the most responsive and pleasing sound of any planar magnetic headphone ever built.


[ RINGS ]
Our goal from the start was to create an aesthetic design worthy of our premium sound. Using materials such as Micarta, stabilized choice woods, rocks, gems, and other unusual materials we can fit into our casting mold, no two rings will ever be the same. The rings are a chance to express your style and personality. Short of concentrated dark matter, if you have a special object that you want casted into a pair of one-of-a-kind rings, visit our custom shop.


[ HEADBAND ]
Weight management is always a difficult factor with planar magnetic technology, which is why we pay close attention to the headband. We focus on offsetting the weight with balanced headband curvature, proper clamping force, and perfectly dense ear pads. The result is the most comfortable planar headphone with the smoothest size adjustment design ever created.


[ ASSEMBLY & TESTING ]
While one team works on the rings, another team assembles the headphones in small batches. We “preburn” every pair at 120dB for a minimum of 15 days to ensure they are ready for our listeners to enjoy. The speakers then go through a final round of testing to validate they are within +/-0.3dB for both left and right channels.


[ CASE ]
For safe transport, every headphone ships in a durable, water resistant “Pelican” style case. Every case has custom cut foam to carry your headphone, cables, and accessories you’ll need for listening away from home.
