NEW - 2016 Model is now in stock. Featuring a recessed silver carbon barrel for better grrip and slightly improved internal dimension.
All Eidolic 1/4" connectors come with rubber grommet for step down to smaller cables and strain relief without needing to use heatshrink.
Eidolic 6.3mm Plug
The Eidolic 6.3mm (1/4”) connector for headphone & professional audio makes its debut with unique, unmistakeable styling, formidable build quality, and optimal electrical performance. The focal point and nerve center of the best headphone cables…
A design first.
This connector is the headphone world’s first glimpse at new carbon fiber finishes, featuring silver carbon fiber inlaid into a custom-textured aluminum barrel that combines low mass and high strength. All contact surfaces are plated with pure rhodium and the barrel is highlighted by a dark grey Eidolic icon. The Eidolic 6.3mm connector stands alone in aesthetics.
Function over form.
Before Eidolic could offer the most refined 6.3mm connector in audio, a number of variables had to be considered. The plug barrel features a generous 10mm rear opening that fits an included rubber grommet, obviating the need for heatshrink. All the inner barrel surfaces are anodized, preventing shorts, and the contact tabs were optimized to easily take up solder with low heat. The engineering plastic used for insulation can withstand extended applications of intense heat without breaking down & losing form or disrupting the integrity of the signal connection. The contacts are widely spaced so that any cable design can be amply accommodated. The needs of the production cable technician are the foremost concern.
Superlative audio performance.
The nonconductive aluminum barrel provides ample shielding for the signal wires and the copper alloy plug chassis is the best blend of rigidity and conductivity. The connector’s heavy layer of rhodium plating endures relentless cycles of connection/disconnection without losing plating to abrasion; rhodium is prized for its combination of conductivity and hardness.

IACS (International Annealed Copper Standard)
The IACS rating is the metric used to describe a metals conductivity as compared to the standard of copper.
First take a look below at pure metals conductivity ratings.
(1) OCC Pure Silver - 107%
(2) OCC Copper - 103%
(3) Copper (common grade) - 100%
(4) Gold - 73%
Silver is the best there is, in pure form, period.
If you take a 1"x 1"x 1" cube of pure silver and compare its conductivity to an identical 1"x 1"x 1" cube of gold, the gold is considered 32-35% less conductive than the pure silver.
An alloy, by definition, is less pure than the original pure metals it is comprised of. Alloys are in existence largely for strength / hardness properties and are not meant for high end audio cables. When you alloy a metal, say gold with silver, you quickly decrease its purity and IACS rating. Even at just 1% gold alloyed with silver the IACS rating drops down well below plumbing grade copper. Alloys in the audio world came about purely as competition increased and there was desperation for new ways to try and market a cable to the uneducated masses.
Norne Audio will always utilize the purest form of a metal and will always use pure silver occ litz, pure copper occ litz, spc occ litz or mixes thereof. Our goal is the design that possesses the absolute top specifications of the highest possible quality.
