Description
Enhanced Cable Structure: Shielded, Oxidation-Resistant, and Luxuriously Soft
The 2DualCPS cable is ingeniously named for its dual-twisted, Teflon-coated conductors, encased in a medical-grade TPU sheath. This intricate design offers a triple advantage: firstly, shielding against both internal and external electrical interference; secondly, preventing oxidation of conductors; and thirdly, providing a comfortable, aesthetically pleasing, and soft user experience.
Concentric Stranded Conductors: Precision in Signal Transmission
Crafted with concentric stranded conductors, the cable's central core wire is enveloped by helically laid wires, ensuring a regular pattern that eliminates signal loss. Coated with Teflon, these conductors undergo a swift manufacturing process, limiting oxidation to less than 4 days.
C - Concentric-Lay Structure: Stability in Signal Transmission
The Concentric-Lay Structure is employed to counteract the negative magnetic effects. In contrast to irregular patterns found in ordinary structures, the Concentric-Lay conductors have a circular cross-section, distributing signals evenly. This design ensures stability in high-frequency response, even under external forces like bending, as the internal structure remains organized.
P - Purified Process: Purity Throughout the Manufacturing Process
Impurities are systematically removed through a meticulous purifying process integrated into every stage of manufacturing, ensuring the 2DualCPS maintains exceptional purity. The wire drawing process occurs in a protective liquid to prevent oxidation.
S - Silver: Achieving Balanced Sound
Utilizing the OCC method, with impurities less than 10PPM, the 2DualCPS incorporates silver for optimal electrical conductivity. Thanks to a smooth surface achieved through natural diamond-made peel holes, the sound produced is balanced, eliminating the traditionally associated excessive highs.
Unrivaled Sound Quality in Three Aspects
Clear - Supreme Sound Resolution: The 2DualCPS offers unparalleled clarity, projecting even the smallest musical details, setting a new standard for sonic precision.
Sound Stage - Expansive and Interference-Free: The cable's unique structure creates a vast sound stage with a clear background, minimizing interference between vocals and instruments.
Steady - Powerful and Balanced Bass: Recognizing bass as the foundation of sound, the 2DualCPS ensures a steady and lively bass response, complementing a diverse selection of connectors.
Connectors: Craftsmanship at Its Best
The connectors, sourced from the OEAudio supply chain, boast 3U Gold Plating for superior conductivity. Using double injection molding technology, these connectors surpass hand-soldered alternatives in quality. The earhook-free design, paired with a soft plastic slider, allows versatile connections to various earphones.
Customized Oyaide Solder: Enhancing Detail in Sound Performance
Employing customized Oyaide solder with 4.7% silver content, the 2DualCPS undergoes low-temperature soldering for precise sound performance down to the minutest detail.

6. OSTs from movies and anime.
7. Instrumentals (mostly jazz and jazz fusions).
As clear from the above list, most of my music is mid focused. I am not a bass head, though I appreciate bass if the music calls for it. I prefer a detailed, neutral and natural sound signature.
I had purchased Penon Voltage recently. This IEM has a 2 DDs / 4 BAs and 4 ESTs configuration. The stock cable of this IEM is Obsidian from Penon itself which has a higher cost than OE. It was immediately clear that the stock cable is inhibiting the performance of the IEM since the resolution and the imaging while good, were not on par for the driver configuration on offer. I had a feeling that the IEM needed a cable which had silver (not silver plating) in it. I picked this cable which is a 4 wire purified silver cable. Lo behold! the technicalities of the Voltage just jumped 2 levels - resolution, imaging, separation and the layering improved very noticeably. I had my doubts as to whether the silver will affect the bass of the IEM as silver wires typically tend to increase the speed and make the upper mids and treble sharper making the IEM brighter. However to my ears, the quantity of bass of the IEM remained the same (compared to the stock cable) while the note definition for the lower ranges became more defined. The treble became more etched without any kind of sibilance. The note weight is very good throughout the range and sounds very natural.
Comparisions:
Penon Obsidian cable (priced $150 - roughly INR 14,000/-): Superior to this cable in all the aspects be it Lows, Mids, Highs and technicalities. Bass quantity roughly the same for both, but basslines noticeably more cleaner and defined with OE.
EA Cadmus 8 wire (priced INR 24,000/-): Technicalities: Better detail retrieval, separation and layering on OE than the Cadmus. Cadmus has a wider soundstage. Better treble extension on the OE. Both Cadmus and OE are very good in the mid range with different strengths. OE is more clearer and detailed in the midrange (my requirement for Voltage) while sounding natural. Cadmus has a thicker note weight in the midrange which sounds really good for vocals. Cadmus has more bass quantity with good definition in the bass lines. However OE has noticeably more tighter and defined bass while losing out to the Cadmus on the quantity of the bass slightly (mainly in the mid bass).
This cable is very comfortable as it is thin by the cable standards these days. You forget that there is a cable within a few seconds of wearing this. Honestly I find it difficult to correlate the quality of the sound provided by this cable to its unassuming appearance. This has to be one of the best deals when it comes to cables.
Who would I recommend it to: 1. To those who are looking for added technicalities and treble extension without sibilance 2. Those who have warm IEMs and want more resolution and bass definition.
Thanks, Pritam for the prompt delivery. Always a pleasure dealing with you.

The carry case is spacious enough for keeping one IEM and one small portable DAC with cable. Like I have kept Muse M4 dac with dihifi cable and one IEM in it. And the shell is hard so no chance of anything happening to the IEMs.
Was the cheapest option for a replacement cable I could find anywhere. And it works flawlessly too, no complaints
Amazing product
I recently purchased the Castor Pro KC earphones, and they have exceeded my expectations. The bass is deep and punchy, yet it doesn't overpower the mids and highs, ensuring excellent instrument separation. The tuning switches offer great flexibility, allowing me to customize the sound signature to my preference. Build quality is solid, and they are comfortable for long listening sessions. Overall, these IEMs deliver an impressive audio experience at their price point!

Very good cable
Works with 0.78mm 2pin iems
Using LG g8x thinq and output is higher than the smartphone's 3.5mm output.
