Symbiote SP IEM Cable for Sirens Series:
JH Roxanne/Layla/Angie/Rosie/New JH13v2/Lola
4-wire or 8-wire Silver Peptide OCC Litz
We are finally offering a Sirens Series (JH 4 pin) cable of our own design, with a unique concept that has been slowly refined since the release of the first Roxanne IEMs. This cable features the same top-grade materials & design as our Symbiote SP flagship for CIEM/MMCX, but customized for JH Sirens series.
The Eidolic JH Sirens Series connectors are now the cornerstone of this remarkable cable. These plugs were custom designed from the bottom up with all beadblast aluminum barrel & nut, white Eidolic logo, ultra high strength insulator, and gold-plated phosphor bronze contacts. These are light-years ahead of any other Sirens Series connector on the market in build quality and fit, and are standard on all Sirens series cable orders.
No more adjustable bass controls. The 4-pin JH standard uses over-tuned bass combined with selectable bass attenuation (a resistor or volume control) to control the bass “boost.” With DHC, audiophile-grade resistors are hidden inside the amp-end termination plugs. This design is our creation and sets the bass level using discrete, non-moving, precise parts that are exactly matched between left and right channels and will never wear out or break. The bass is set to an optimal 50% (50 ohms) setting, comparable to “12 o’clock” on the stock cable. We can accomodate requests for more or less bass but 50% sounds best to our ears (25%, 75%, 100% bass also available – leave a note during checkout).
For 8-wire, we use full-size Dale PTF resistors, which have some of the tightest specs of any resistor ever designed, way outside of what is required for this application.
For 4-wire, we bypass the need for extra wires by having the bass level be set with tiny MELF SMD resistors with super-strict specifications soldered directly between the plug contacts inside the Sirens plug.
DHC’s best wire. Our “Silver Peptide” (SP) OCC silver type 4 litz wire is the most conductive, highest performing litz wire on the market. It has no downsides or drawbacks other than cost – it is a more detailed, transparent, revealing version of OCC copper litz. It will never oxidize or degrade due to the invisible litz enamel on each strand, and is internally damped by a pure cotton core at its center. This wire is extremely compact and flexible, and will not weigh you down or make its presence felt. This no-compromise 8-wire design offers the best possible sound for Sirens series.
We also offer a more compact and economical 4-wire model – this cable is so travel-friendly and light that it bears no resemblance to the stock cable…
DHC does not use alloys or add gold to its wire, as these impurities reduce conductivity. Adding just 1% gold to wire reduces conductivity by more than 15%, and defeats the purpose of using high purity silver or copper. We also do not gold-plate wires, as gold is less conductive than silver and slows down frequencies traveling near the wire’s surface.
Eidolic connectors. The top-performing, best-looking 3.5mm and 2.5mm plugs money can buy – their quality has never been equalled or surpassed. The pure aluminum, beadblast-finish IEM plug barrels from our other Symbiote IEM cables are a perfect fit for the JH Roxanne/Layla/Angie connector piece.
Y-split greatness. The y-split — the point where the cable splits off to left and right earpieces – is DHC’s chance to perfect the cable’s appearance. Our ultra-compact “Capsid” V2 y-splitters are tiny cylinders of CNC machined, beadblasted aluminum wrapped in real black carbon fiber – and are available in silver or black anodized finishes. For a truly exclusive cable, pick one of our 3D printed splitters – designed by us and professionally printed in investment-cast, hand-polished metals like sterling silver, pure bronze, or rose gold plated brass. For the most bold styling choose one of our Eidolic splitters with unique color & material combinations.
Upgrade to titanium. Eidolic offers a one-of-a-kind titanium alloy upgrade barrel with laser logo and choice of decorative insert. For more information, click here. Check the boxes above to opt for these truly unique styles. For 4-wire Sirens cables, we also offer the Eidolic titanium slider, an amazing invention incorporating a titanium frame and silicone band that securely cinches your cable while looking amazing. To bring it all together, opt for the ultracompact Eidolic E-SXT y-splitter. All Sirens cables include a free upgrade to the DHC titanium CNC logo tube in lieu of the standard DHC CNC aluminum logo tube. See below:
Why are fixed resistors/bass level the only option?
The bass control box is fine for the stock cable, but its parts (Tocos G43 trimpot resistors) are only rated at 100 uses before they reach end of life. If you use the stock cable to decide which bass level you most prefer, we can get a close match with our fixed resistors. It follows that one would not change the bass for every song, or else even the stock cable will wear out; even changing it whenever your mood changes would lead to the same result. Once you know the right setting, it should be consistent over time for that particular music player/amplifier.
Beyond that, it is impossible to set the bass to the exact same level for left/right using the included screwdriver – you have to use a multimeter to check resistance for the cable’s left & right connectors to see whether they’re configured identically. With DHC, bass levels are matched.
50% (50 ohm bass) is standard; we also carry resistors for 25% and 75% bass, leave a note in the order comments.
