Eidolic 2.5mm “spacious barrel” for Astell & Kern 4 pole TRRS


Perfect size and shape.  The 2.5mm connector must be a perfect fit for the exacting specifications of the Astell & Kern lineup, while allowing an easy installation of a variety of headphone, interconnect, and in-ear-monitor cables.  We have a streamlined 10mm barrel diameter that will fit very compact jack layouts, but a 8mm front and rear opening will fit the vast majority of cables.  The flush front face allows dimensional stability when mated with the music player, preventing jack stress.  Barrel length has been reduced slightly for better portability.

Ideal installation conditions.  The solder contacts inside the plug are thoroughly insulated and properly spaced to allow effortless cable installation.  While all 4-contact plugs require extra attention to install, there is even more room inside the barrel than before so that your cable can be soldered with less difficulty than before.  This design has been prototyped and tested over an extended period to ensure it goes the distance – over the past 2 years its track record has been stellar.  The barrel 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 2.5mm balanced plug for Astell & Kern 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 gunmetal gray anodized aluminum shell is textured with a proprietary process that yields a tough, matte finish that sparkles in the light.  A distinctive gray 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.
