The Eidolic 3.5mm TRRS 4-pole balanced plug is a complete solution for the balanced 3.5mm connections, featuring a simplified installation process, enhanced durability, superior ergonomics, and a unique appearance. These connectors fit the following diverse applications:
Cell phone remote/mic compatible 3.5mm plug
Hifiman balanced music players (HM-901 and more)
Sony NW-ZX2 and other balanced Sony players
Geek Wave, Geek Out V2, Geek Out V2+, and other balanced Light Harmonic Geek gear
Oppo PM-3 balanced earcup connection
Customized players like Red Wine Audio RWAK240 and RWAK380 and MZAK240
JH JH3A digital connection
Or use it as any 3.5mm connector by joining the two innermost contacts together.
Perfect size and shape. The varied dimensions of 3.5mm headphone jacks offer a unique challenge to the audio cable industry and anyone looking to build a high-performing cable. There are few if any high-quality balanced 3.5mm plugs. We have a streamlined 10mm barrel diameter that will fit very compact jack layouts, but a newly-expanded 8mm rear opening and 8mm front opening will fit the vast majority of cables. We have also shortened the barrel slightly to make the plugs less obtrusive.
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. 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 strength combination of gold and brass is employed for this connector. Superior plating thickness and complete plating of all plug surfaces set this connector apart.
Unique barrel aesthetics. The Eidolic 3.5mm balanced plug is incredibly light and compact due to the choice of materials, which also confer a near-indestructible exterior; the revised dimensions reduce weight slightly. The new black anodized aluminum shell is textured with a proprietary process that yields a tough, matte finish that sparkles in the light. A distinctive crimson Eidolic logo is screened and cured onto the upper area of the barrel. Even the most abrasive conditions will not harm the exterior of these connectors.

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.
