Before and After
Rollover for the Magnum Advantage
The ultimate upgrade for Grado/Alessandro headphones

Your original headphone has its plastic chambers removed and replaced with all-aluminum designs. We have not simply duplicated the original part; it has been engineered to allow greater air volume behind the headphone driver to extend low frequency response.

Aluminum materials are pretreated using a special anodizing method optimized to increase surface porosity. This process helps reduce ringing by absorption and damping of undesirable vibrations. The result is an ultra-strong headphone assembly with perfect resonance control. Click here to discover why aluminum was selected as the material of choice in the Magnum enhancement.


The ultimate upgrade for Grado/Alessandro headphones

Following the removal of plastic assemblies, we extract the existing drivers and carefully mill away excess plastic until we are left with the exposed driver surface – a process of delicate precision as the driver is permanently bonded to its plastic assembly.

Once the driver has been carefully milled, we use a special solution to remove the manufacturer’s original “destressing” compound. The goal of the new coating is to offer appropriate damping while being feather-light in order to promote ideal transient response. Drivers are verified throughout production to ensure they maintain 0.05db matching. Find out more about our coating technology.
