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 great, every element of a song is well balanced. However, that balance is a double-edged sword, as it lacks bass. So, if you're looking for a strong base signature, you might want to choose something else or use an equalizer, which is what i'm doing.
This is a solid cable, which delivers stunning sound. I use this cable to connect my Hifiman EF400 to Fiio K15. This is a major upgrade to the sound (as compared to the two standalone).
I bought Cadenza as my first IEMs, before buying these I researched a lot about every kind in this budget I could go for, I streched and bought these as something which sounds, harmonious, smooth and comfortable for long sessions, even then the details and the sound still puts me in awe beating any earbuds and in ear sound system I have ever tried.
One of the best IEM.
EarAcoustic STA-Hi End Series IEM is too warmform me which is my sound signature. Beryllium driver tuned so fantastic. When was received this never go off from my ears to 4 hrs. I have so many brands and so many chifi IEMs used but this EarAcoustic STA-Hi End Series IEM is totally blowned me away. That's why this EarAcoustic STA-Hi End Series IEM is highly recommended. Thanks once againMr Pritam Ji for suggesting me so wonderful IEM in audio library collection.
The product came with all the accessories it should have, the box wasn't damaged at all and delivery was quick. It only took 2 days to be delivered and came with good enough packaging.
Overall, Very satisfied by theaudiostore. While this was my first time buying from them, It definitely won't be the last.
When I was a kid, somewhere around 2005–2007, I was gifted a Sony cassette Walkman. I was too young to care about model numbers or sound signatures. I just knew that pressing play felt important. That Walkman is gone now. Probably sacrificed to the great black hole where old chargers, socks, and childhood joy go to die. But the want never left.
So years later, I did what any emotionally stable adult does. I bought a Walkman again. This time, the Sony NW-A306. And no, this is not nostalgia cosplay. This is something else.
-> A Small Device With Strong Opinions:
The NW-A306 looks like a cute mini smartphone that went on a digital detox retreat. No camera. No speaker. No SIM. No “bro just one notification”. It exists only for music and has zero interest in your productivity apps or reels.
Physically, it feels solid and intentional. Buttons still exist. Sony clearly assumes you might listen to music without staring at a screen like it owes you money.
-> Android, But With Discipline:
It runs Android 14 and yes, streaming apps work. YouTube, YouTube Music, Spotify, Apple Music, Tidal, ... etc all fine. But here’s the thing, you can choose how modern you want it to be.
With Google services running, I casually listened for about 6 to 7 hours and still stayed under 60 percent battery usage. That’s respectable. Disable Google services and background nonsense, and suddenly the battery life becomes “arre yeh toh chale hi ja raha hai” level good.
Sony didn’t brute-force anything. This device feels tuned, not overpowered.
-> Sound - Sony Being Sony:
Let’s clear this upfront. Walkman is the legacy on which the iPod later thrived. Apple polished the idea. Sony invented the feeling.
And yes, it is Sony, so bass exists. No question about that.
The bass here is not the shaadi DJ type that enters before the song does. It is controlled, confident, and supportive. With KZ ZAS and Sony XM4s, the sound is clean, warm when needed, detailed when it matters, and never tiring.
As a USB DAC, this thing is frankly ridiculous for its size. Plug it into a PC and it behaves like a serious audio device pretending to be small for fun. Stable, clean, no tantrums.
This is not five-minute wow sound. This is “ab bas ek album aur” sound.
-> Local Music and the Joy of Making Things Difficult:
Now comes the part streaming apps will not like.
Yes, we have everything. Spotify, Apple Music, Tidal, Amazon, Qobuz, YouTube. Music is everywhere. And somehow, nothing sticks.
Algorithms keep suggesting. You keep skipping. Half the time you don’t even remember what you listened to two hours ago. Music becomes vibe. Background. White noise with feelings.
Owning music changes behaviour.
Ripping CDs into FLAC, fixing metadata, web scraping album art, organizing albums. This is effort. And effort creates attention. You listen to albums. You read lyrics. You notice production. You sit still.
Sony Music Center on Windows actually helps instead of testing your patience. Metadata, album art, even 12-tone analysis. Organizing music feels intentional, not like punishment for liking files.
The NW-A306 makes music feel yours. Not rented. Not borrowed. Yours.
Ironically, it uses modern tech to make things slightly complicated on purpose, so listening becomes simple again.
-> So Why Does This Exist?
The NW-A306 is not trying to replace your phone. It is reminding you why music once deserved its own device.
It is focused. It is disciplined. It does not beg for attention. And that is rare now.
If you treat music as something to truly listen to and not just something playing while you scroll, this Walkman makes complete sense. Emotionally. Practically. Logically.
Also, it feels really good to own your music again. Like, irrationally good.
Some loops are worth closing.
i was scared what if i will get scammed, or will the put stone in the box ,
but nothing happened like that, best unboxing experience, do take video, as its mentioned in the package either,
product 10/10
the only issue the extra included case has no guide how to put earbuds in it and as i am an idiot i inserted it wrong took 45 minutes reinserted, fites to tight,
if you are stuck just like me - [****] email me i will help,
best audio , ANC is decent, call good, battery decent, overall excellent package, didnt find in ear detection, or find my earbuds only thing which arnt deal breakers
Amazing product and quick delivery.
There is no hissing sound with Kefine Klean iem
It's really a good beginner iem who qre comes into the iem first time
From perspective the wide bore tips were very flat in term of eq, normal bore and silicon tips performanced the best
Alleviated my qualms about wax entering the vents of the softears volume s.
Would recommend, works as advertised.
I picked up the Xenns Tea Pro from The Audio Store a couple of months ago, and after using them daily, I feel ready to share my thoughts.
First off, huge shoutout to The Audio Store team in Pune. The buying experience was smooth, and they were super helpful with my queries. It’s always reassuring to buy from folks who actually understand the gear they sell.
As for the Tea Pros—they are special. I’ve had them for a while now, so the "new toy" excitement has settled, but I’m still reaching for them every single day. The fit is incredibly comfortable for my ears, even during long listening sessions.
Sound-wise, they have that magic "Tea" DNA but feel more evolved. The vocals are lush and front-and-center, which makes tracks feel intimate. The bass has a solid, authoritative punch without bleeding into the mids, and the treble is detailed but smooth—I’ve never felt any fatigue, even after hours of use. The soundstage is holographic; you can really pinpoint where every instrument is coming from.
If you’re on the fence, just go for it. They have been a fantastic upgrade for my setup.
