Rosson Audio Design RAD-0 Open-Back Planar Magnetic Headphones

Our Craft
We make open-back, over-ear, planar magnetic headphones for discerning music-lovers. Each pair is custom made with durable and premium materials, no two headphones will ever be the same. The headband, housing, and transducers are all hand made by a small team of craftsmen. If you’re looking for mass-produced, plastic audio equipment, these are not for you.

66mm Transducer
Designed and manufactured 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.
