Driver Coating
The ultimate upgrade for Grado/Alessandro headphones

The driver is the heart of any headphone system, and Symphones’ proprietary driver coating is the apex of our upgrade technology.

A newly developed coating material was created to address unwanted bending modes within the diaphragm surface. A unique ability to ‘tune’ driver response results in increased clarity throughout the frequency extremes. The coatings attributes together with its precise application ensure accurate and dynamic reproduction of even the most complex musical passages.

The sound? Clean, pure, and smooth—our driver coatings bring a new level of performance to headphone modifications.
