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.

I purchased these during christmas- and my initial impressions were that these were packaged well, and felt very premium in hand, except for the cable.
The bazz is very lacking, and the iems are unusable without tuning. After tuning these sound full, and have beautiful clarity. Definitely recommend if you can tune them. Also very good for video editors and others who need stock audio
It sounds wonderful 👍
I am very satisfied with my purchase and currently enjoying hi-res audio with my iem. Best looking and build quality is also good under 1K
This is my first IEM. I like the way it sounds. Though I expected much better soundstage but it is good. After using this, I will definitely buy my second IEM. Trust The Audio Store, they delivered as expected. Actually someone suggested me on reddit to go with audio store and I will definitely recommend others the same.
Just got some time with these and here's my honest take:
Comfort: These things are stupid comfortable. Lightweight shells that disappear in your ears, zero fatigue even after long sessions. Stock tips are meh though—nothing special, you'll probably want to tip-roll.
Sound:
- Vocals are pushed forward and warm with less sparkle/energy up top. Great for that intimate, smooth vocal presentation but not if you want bright, analytical vocals
- Bass is elevated and textured but definitely not basshead levels. Hip-hop/EDM heads will find it lacking
- Treble rolls off early = excellent sibilance control. Zero harshness or fatigue, perfect if you're treble-sensitive
Who's this for? Warm vocal lovers and anyone tired of harsh, sibilant treble. Long listening session champs.
Who should skip? Bassheads, treble sparkle chasers, people wanting analytical/reference sound.
For the price, these carve out a nice niche—they're not trying to do everything, just warm and smooth really well. Worth it if that's your vibe.
Very Crystal Clear Sound And balanced Bass as human ear appreciates (Harman Tuned). For me my expectations matched. Now it's time to see how longer time it's sustain .
After using 4–5 budget to mid-range IEMs, the Simgot EW300 feels like a refined upgrade after one month of use. The sound is well-balanced with clean mids, smooth treble, and controlled bass, No fatigue after long use. Clarity and instrument separation are noticeably better than my other IEMs. Thanks to the TAS and Pritam for auditioning multiple IEMS and helping me choose the this IEMs.
This is an all rounder headphones. Sub bass is extended which can be easily EQ d. Treble is decent.The mids are a bliss. A note for AUDIO STORE: PLEASE DON'T CHEAP OUT ON THE DELIVERY. The headphones were sent by road claiming to be more than 2 kg. It was just 845 gm. Also if bluedart is not working out please get another delivery partner. Imagine a 30k headphones bumping around for a 1000km. The headphones wires came attached which is not correct. Despite all this thank God there was no damage to the headphones.
If you have a budget of Rs 4000 and looking to buy an IEM which can do it all, look no further than Kefine Klean. With two tuning nozzles, one warm and other bright, you are sorted for multiple musical genres.
GREAT Product under 2000,must buy
to be concise this is probably the best iem under 35k,
Pros:
- Sub bass and mid bass clarity, quality and volume is amongst the best, this is not a basshead iem but will definitely please a basshead.
- Mids are not recessed and are as accurate as they can be, however are not vocal forward per se but are slightly elevated compared to "v" shape iems, giving this iem a mild "W" shape signature.
-treble is good but for me was very much dependent on the tips I used, when using with sancai wide bores trebles were nice and clear, bright, might be too energetic for some, however with regular tips was perfectly tame and not sibilant to a point of discomfort and had decent air.
So use wide bores if you want to open up the iems, get a little better imaging and seperation but might make the highs a little too energetic, and with regular tips you get more boomy bass but might lose a little of the stage width but is better for treble sensitive folks.
Cons
Condensation issue might be there on rainy days, the wing style fit may not work for all, the iems are medium size and can fit many ear sizes especially with smaller tips but if you don't do well with wings or have atypical ears it may not be for you.
is reminiscent of new meta style tuning, so if you have iems with similar tuning this may be redundant.
Overall:
9/10 literally doesn't get much better than this whether you're putting in 5k more of 1 lakh more, this is the point of diminishing returns, atleast in my opinion, and from this price point on its mostly accesories or timings which actually make a difference.
fit and comfort was amazing for me, i have normal ears, with smaller canals, fits very well for me with small tips, but might have a few pressure spots depending on the ear.
build quality is very good with a nice metal shell.
The cable is very good and premium, accessories are good, and has a premium feel and looks beautiful with good presentation, over-all worth for the money, atleast for me lol.
however you may want to wait for more reviews on the hype 4 mark 2 and the new tea pro SE, and if you're a basshead the martillo is going to be potential endgame.
Very smooth, once you find the appropriate size it will work wonders.
Got the KZ Castor Pro (Harman Target + improved bass) and I’m honestly happy with it right now.
Bass hits nicely and feels punchy without covering up vocals.
Songs sound clean and balanced, and details come through pretty well.
Comfort is good for longer listening too.
Overall, feels totally worth the money.
* might update Review later If my views and experience changes
It's hard cast to secure your IEM and soft on inside to don't scratch the IEM & good space on in side
One year review: incredible audio quality, strong bass, clean highs, and no wear or tear. These IEMs are truly reliable
