Eidolic IEM connectors are the new industry standard for durable, functional, and beautiful IEM cables.  Featuring a complete re-engineering of the popular IEM connection types, Eidolic has solved the durability and fit issues that have plagued the hobbyist-grade connectors currently being sold, while allowing anyone to build enduring, truly custom cables for most in-ear monitors.  Eidolic now offers a true flagship MMCX plug, with the best possible insulators, platings, and contact material, plus an industry-best barrel locking method.  Unique styling marks this plug as the completed evolution of the IEM connector.

Compatibility.  With the Eidolic Premier MMCX connector, there is excellent compatibility with Shure, new Westone, Campfire Audio, and countless others with the round MMCX locking plug.

Features.  The connector barrel is made of media-blasted aluminum rod stock lathed to precise specifications, with a new pure white Eidolic logo and engraved ring on each barrel.  The Eidolic Premier CIEM plug easily catches the eye with a silver-white motif.  Colored elastic rings which nest in the barrel’s engraved ring serve as a left/right label.

Premier insulation.  The Premier MMCX connector brings a gold-plated tellurium copper center pin to the MMCX connector.  The connector features strong Teflon insulation for worry-free soldering.

Improved dimensions and ease of assembly.  These connectors offer a little more space inside the barrel compared to other IEM connectors, allowing a variety of cables to fit and providing secure strain relief & protection of the solder joints inside.  Just solder the worry-free heat-resistant contacts, push on the barrel until it clicks, then fill with hot glue for strain relief.   The nonconductive, anodized aluminum barrel will not short the solder contacts in the event that it is in contact with wires or solder joints. There is no tapering on the 4.4mm rear hole to maximize the amount of glue (and wire) that can fit inside, for improved reliability.  We guarantee these IEM plugs are faster and less tedious to assemble than any previous connector.

Superior conductivity.  The materials we have chosen for the connectors’ center pin is both durable and highly conductive.  The specific choice – tellurium copper – is 93% as conductive as pure copper, while being a strong and machinable metal suitable for audio connectors, far exceeding the 20-30% conductivity rating of brass, steel, or bronze.  Eidolic goes beyond simply employing a TeCu center pin – the entire body of the contact (including the negative/ground contact) is tellurium copper – an industry first.  Years of titrating the exact right pin dimensions yields a pin that is neither too thick for brand new IEMs, nor too loose on older, more worn IEM sockets.

Upgrade to titanium.  

Bringing the brilliant functionality of the Eidolic E-STB titanium modular barrels to the tiny scale of CIEM/MMCX, the E-STBC features a three piece titanium design that retains the click-lock functionality of the Premier Eidolic IEM series while allowing modular customization. The upper and lower parts of the barrel thread together, securing a contrasting high polish aluminum insert in place. The Eidolic logo is laser-engraved, the barrel is circular-polished, and the edges are chamfer polished. Complete the ultimate titanium cable with E-STBC and Eidolic’s matching slider, splitter, and amp-end barrels.
