The EarAcoustic STA Pro is a precision-engineered dual dynamic driver in-ear monitor built for audiophiles, professionals, and critical listeners who demand clarity without fatigue. Featuring a 10mm ultra-clear composite diaphragm for authoritative bass and natural mids, paired with a 6mm high-speed composite driver for crisp, controlled highs, the STA Pro delivers a wide soundstage, clean transients, and rich micro-details across the frequency spectrum.
Powered by Tesla-level N50 magnets producing ~10,000GS magnetic flux, the STA Pro achieves ultra-low distortion (<0.5% THD), lightning-fast <3ms transient response, and a tightly controlled ~50ms bass rebound. The result is a smooth, balanced, and immersive sound signature with excellent instrument separation—ideal for long listening sessions, studio monitoring, and high-resolution music playback.
At the heart of the STA Pro is a dual-core dynamic driver array.
The 10mm graphene-infused diaphragm handles lows and mids with authority, texture, and speed
The 6mm composite diaphragm delivers extended, airy treble without harshness or sibilance
This configuration ensures natural timbre, fast decay, and distortion-free dynamics, allowing vocals, instruments, and ambience to remain clearly defined even in complex tracks.
The EarAcoustic STA Pro is tuned for neutral-leaning balance with musical warmth:
Tight, controlled bass with realistic impact
Forward yet natural mids for vocals and acoustic instruments
Smooth, airy treble that reveals detail without fatigue
Its holographic presentation and wide soundstage make it versatile across genres—from EDM and rock to jazz, classical, and film scores.
Inspired by the 2025 Year of the Snake, the STA Pro features serpentine resin faceplates with iridescent scale detailing and flowing contours. Crafted in Shenzhen, the shells blend mythical artistry with modern acoustic engineering, making the STA Pro as visually striking as it is sonically refined.
Designed using real-ear canal data, the STA Pro’s lightweight zinc-alloy shells offer:
Secure, low-profile fit
Effective passive noise isolation
Reduced pressure points for extended listening
Multiple eartip sizes ensure optimal seal and comfort, whether at a desk, studio, or on the move.
Included is a 1.2m high-purity 0.78mm 2-pin detachable cable, constructed from oxygen-free copper and silver-plated mixed-weave strands. Professionally built for pure signal transmission, it offers:
Zero audible microphonics
Minimal signal loss
Durable, tangle-resistant construction
The detachable design also allows easy upgrades with aftermarket cables.

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,

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.

Kz edc pro iem are the best for the beginners and in budget segment under 1000 rs love the audio the audio is crisp clear
I like em
Coming from a guy who upgraded from the KZ EDX PRO,
The Fatiguing treble and the bass bleeding into everything really annoyed me and it was tiring to listen to for long sessions
After purchasing the Tanchjim bunny, all of these problems just, VANISHED!
Excellent sound separation
Clean vocals
Well-tuned tight bass which feels intentional, and doesn't bleed into any other frequencies - It hits when it needs to!
Every detail is noticeable.
It was better than the One I purchased previously.just that it has more based which gives unclear information while gaming that can also be removed by EQ
Great earphones for the price! Kefine Klean has strong bass that hits hard, clear vocals, and nice treble. Build is solid metal, feels premium. Super comfy for long use. Best under 4000rs, highly recommend! 5 stars.
Nice and premium
They sound great, with loads of detail and a decent soundstage, they're not very dark like some reviewers say, at least in my opinion. I'd say they're mildly u-shaped, pretty musical. They also respond to EQ, not as easily as planar headphones maybe, but still well enough. And they're comfortable for me, but that's subjective.
These IEMs sound really good for everyday listening. The bass has a nice punch, vocals come through clearly, and the overall sound feels balanced and enjoyable. They’re comfortable to wear for long periods and block out a decent amount of outside noise. Easy to carry around as it comes with a pouch, and great for music, videos, or calls—definitely worth it for the price.
I picked up the GK Kunten after seeing it absolutely everywhere on Reddit. Thread after thread, comment after comment, people calling it the next budget miracle. Curiosity got the better of me. The moment stock landed at The Audio Store, I walked in and grabbed a pair.
First impression straight up, the hype isn’t imaginary. For a sub 1k rupee IEM, the Kunten is shockingly competent. Tonally, it keeps pace with plenty of IEMs in the under 5k range. The tuning feels deliberate, not accidental. Clean midrange, vocals forward enough to stay engaging, treble present without turning sharp, and bass that has texture instead of just thump. It does not sound cheap. That’s the biggest compliment I can give.
What it doesn’t do, and this is important, is magically destroy everything above its price. Some online takes made it sound like a giant killer that humiliates multi-thousand-rupee sets. That’s exaggeration. The Kunten is excellent for the money, but higher-tier IEMs still pull ahead in refinement, separation, and staging. Physics remains undefeated.
Where it really wins is balance. It avoids the usual budget sins. No bloated bass. No piercing highs. No hollow mids. Just a coherent, musical presentation that feels easy to listen to for long sessions. This is why it’s blowing up in discussions. It’s not because it’s unreal. It’s because it gets the fundamentals right.
So yeah, the Reddit hype has substance. Not in the fantasy sense of “best IEM ever made,” but in the real sense of “ridiculously good for what it costs.” If someone blind-tested this and told me it was a 3–4k set, I would believe them.
For the price, it’s a smart buy. Not a miracle. Just a very well-judged product that landed exactly where the community wanted it to.
And honestly, that’s more impressive than empty hype.
Excellent upgrade over my existing speakers, home theater, earphones etc. Using with apple music lossless and it has changed my experience of music completely. Highly enjoyable and accurate sound. No fatigue even while listening to 3 or 4 hours continuously. Very good comfort. Very happy with these earphones
