Eidolic 3.5mm TRRS jack

S$25.00


The Eidolic 3.5mm plug is a clean-slate effort to revolutionize this stand-by connector for personal audio, for a product that allows for a simplified installation process, enhanced durability, superior ergonomics, and a unique appearance.

Design Elements:

Perfect size and shape.  The 3.5mm connector must be small enough to fit all electronics, while large enough to accomodate substantial headphone and interconnect cables.  We have a streamlined 10mm barrel diameter that will fit very compact jack layouts, but a 6.5mm rear opening will fit the vast majority of cables.  The extended, narrow collar behind the plug shaft allows it to fit into recessed openings such as cellphone and music player cases. 

Ideal installation conditions.  The solder contacts inside the plug are thoroughly insulated and properly spaced to allow effortless cable installation, without the risk of shorts or compromised insulation.  In this way, we avoid tiny, stacked contacts that are easy to short and difficult to maneuver around.  This design has been prototyped and tested over an extended period to ensure it goes the distance.  The barrel offers ample room inside and is treated to ensure its interior is nonconductive, and the plug avoids the use of magnetically charged materials wherever possible. 

The best metallurgy for each design.  A high-conductivity, high-copper bronze alloy with superior strength to other base metals is employed for this connector.  We offer nickel, gold, and rhodium-plated variants for a complete range of choices.  Nickel offers superior hardness while gold is most conductive; rhodium is the best of both worlds at an additional cost.  Superior plating thickness and complete plating of all plug surfaces set this connector apart. 

Unique barrel aesthetics.  The Eidolic 3.5mm plug is incredibly light and compact due to the choice of materials, which also confer a near-indestructible exterior.  The anodized aluminum shell is accented with a interference-repelling carbon fiber ring, and the metal surfaces are textured with a proprietary process that yields a tough, matte finish that sparkles in the light.  A subtle Eidolic logo is screened and heat-cured onto the upper area of the barrel.  Nothing short of a hacksaw can damage the exterior.
