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.

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.

These are my fourth pair of IEMs, and honestly, I can’t find a single fault with them. The sound signature is beautifully smooth, well‑tuned, and perfectly balanced. Vocals come through with striking clarity, making every track feel alive. Totally worth it — they deliver an experience that goes beyond expectations.
I’m really impressed with the Hiby R1 — such a compact device, yet it delivers powerhouse performance. The raw specs on a spreadsheet don’t capture the real experience. Once you pair it with Type‑C IEMs and play FLAC files, the sound quality speaks for itself: clean, detailed, and surprisingly dynamic for something so portable. It’s proof that great audio isn’t just about numbers, but about how the gear actually performs in your hands (and ears).
It was neatly packed and unexpected case has been delivered along with the DAC. Had a nice experience too with the product. Loved it!
I've previously owned some budget iems like kz zex, tangzu wan'er and chu 2 but Ohh boy the sounds on STA HI-END is so soothing and melodious and it handles eq like a champ so no complaints from there too. Absolutely go for it you won't regret
Powerful, clear and you can hear the complete trace of audio.
I have been using the Tanchjim Bunny DSP for a while, and for the price, it’s honestly a very good set of earphones. The build quality is very simple but good, and the light weight makes it very comfortable for long usage.
The sound quality is very balanced for the price. The bass is good and controlled rather than overemphasized, and the mids are good so that the vocals are very natural, and the trebles are good and detailed but not harsh. This makes them very good for all types of music.
The Tanchjim Bunny DSP is a very good earphone for the price, and I would recommend it for people who are looking for a very simple plug-and-play earphone with good sound quality.
Sound is very good and accurate.. Soundstage is also wide and deep.. Like this Bunny...
Overall good quality
WelI i loved the iem Its good for my studyinh and music session go for it iems
Bets budget dac that gives you clear mids and more treble extension... If you are into edm trance symphony orchestra style music... then you will hear better instrument separation...
The cable is soft material so not for on the go will wear and tear... If you are musichead and always hooked then better go with audiocular beam it has cavlar braided cable for good rough n tough life space
Heard a lot of stuff on internet about this dac like hitching or buzzing sound and was bit nervous , but after purchasing I haven't faced any problem with it and I'm fully satisfied with the build and sound quality of the product.
This is one of the best case I have used till today. Definitely beats other cases at this price range. It is much better than the generic cases available on Amazon, Flipkart, etc.
I have recommended this case to my friends who were so impressed on seeing it.
Why?
The quality of music that it is deliveing is Awesome . I was not sure if it is worth investing before buying. But after I tested it , it was phenomenal .
Also I would like to thank The Audio Store , they packaged this box so nicely , it has 4 to 5 level of protection, Also I was not expecting the case , it is cherry on the cake, I was bored of that low quality cases.
Thank You The Audio Store
You're the best
