Description
Experience an extremely rich audio performance with the FiR Audio Neon 4. This gorgeous IEM uses the latest IEM tech to deliver spectacular audio with powerful bass, lush mids and extended treble.
Smooth, Creamy & Rich
Enjoy smooth, creamy, high-res audio with the FiR Audio Neon 4. It offers lush upper mids and treble along with an incredible soundstage and positioning thanks to its ATOM XS module. Powerful and detailed bass enhances the listening experience for an immersive sound. The machined aluminium shell with a sapphire glass faceplate encompasses 3 balanced armature drivers and a 10mm dynamic driver.
Deeper than the Ocean
Regular IEMs usually lack depth as they deliver only half the sound. In a natural open-ear environment, the sound is heard in two ways - air conduction and bone conduction. Air conduction is the sound you hear with your eardrums. Bone conduction is the conduction of sound through the bones in your head as it reaches the inner ear (cochlea). Hybrid conduction mixes both. Like the rest of the Frontier Series, the Neon 4 comes in Universal-Fit and Custom-Fit models too.
Feel the Bass
The FiR Audio Neon 4 features cutting-edge Kinetic Bass technology. An open and ported 10mm dynamic driver is optimised to face the IEM shell’s exterior allowing lower frequencies to be transmitted directly to the ear cartilage and surrounding area. These frequencies are converted to kinetic energy that reaches the inner ear via bone conduction. This enhances the bass with an immersive audio experience and off-the-charts bass extension.
Open Acoustics System for an Open Sound
Traditional IEMs use a sound tube with the drivers to carry the sound to the canal stem. However, this creates unwanted resonances and a closed-in, stuffy sound. The FiR Audio Neon 4 is designed with an Open Acoustics System comprising Open Drivers, a Sound Reactor and Sound Reflector for an incredible audio experience.
Goodbye Tubes, Hello High-End Acoustics
By not using sound tubes, the Open Drivers allow sound to flow directly into the Sound Reactor and in turn the ear canal. This ensures a wider soundstage with clear, natural audio. The Sound Reactor chamber shapes the sound coming from the drivers using natural acoustics instead of the dampers and filters used in traditional IEMs. The Sound Reflector directs the high frequencies into the ear canal for extended, smooth and airy treble.
No Pressure, Just Music
An Air Transferring Open Module reduces the pressure that builds up in a sealed ear canal. This reduces fatigue for long listening sessions. The ATOM Venting Technology is instrumental in protecting your hearing while being easy to swap for various levels of bass and noise isolation.
Flexes a Rigid Build
The Neon 4 uses cutting-edge proprietary Rigid technologies for better reliability and durability. The 2-pin connector has been tested for 1,000 seamless connections. It easily fits into the quadrant socket design on the 3D printed shell that’s 20% thicker than the industry average for better durability. A snap screen i.e. an acoustically transparent mesh screen prevents debris from entering the canal stem.

Disclaimer: I prefer mid centric tuning with slight elevation in bass. 65% of my music library is vocal centric.
This is one of the best iem in my collection, this one was a shocker as I remember asking Pritam Bhai what iem would be detailed and have that good amount of slam he gave me two options ie900 and NE4 based on my preference but highly suggested to buy NE4 so I did. That all aside the iem can easily pass as a piece of art, not only that but the solid build quality is a statement in itself. The unboxing experience was also quite a premium one. Especially the included patch and letter makes you feel that you are now part of an elite club and the patch being its insignia.
The music part:
The iems follow a unique W shaped tuning that is quite un common in the current market where everyone is trying to make variants of the same sound signature. It sometimes feels that once you have heard one iem you have heard them all. Amass all the competition these iems do shine differently mainly due to their proprietary technology that is something never heard before.
Bass: Man, what can I say about bass this is one of the best bass I have ever heard in an iem. It feels like there is a subwoofer in your ears. you gotta hear it to believe it. As it has a mid-bass focused tuning so, the sub-bass section doesn't hit like crazy but man when the mid bass comes in it comes hard. Also, it’s not very bloaty or out of control there is a good amount of texture to it. Drums and bass guitars sound very natural and organic.
Mids: The iem’s late midrange dip around 700Hz makes it perfect for songs that are very lively, but due to this it can seem that vocals sometimes take a backseat. Not only that but guitars and male vocals sound great. Though male vocals are presented a bit warm because the pinna compensation starts a bit early compared to other iems in my collection. There is a dip at 3k Hz making female vocals a bit tamer. This all makes for a relaxed listening experience.
Treble: These iems have nice treble presence. The high hats and cymbals sound quite nice and not inorganic at all. There is also good amount of air in them making them sound surreal.
Tech: They are no slouch in the tech aspect. One of the largest stage I have heard in my collection. Also, they do seem more holographic than my Um mest mk2. The microdetails are quite prominent in my music library. Man, to be honest I have heard things in my music that I didn’t even know existed.
Comparisons:
unlike regular comparison section I will like to just make a brief ranking section (of all Totl iems I own) in each section and then give my reason for it.
Bass: Ne4>Mest Mk2>U12t>ExE Gaea>CA ARA. I mean after reading the bass section I don’t think I need to explain it any further.
Mids: ExE Gaea>U12T=NE4>CA ARA>Mest mk2. I do prefer a bit of lean midrange as for me it brings out more of that texture in vocals. The NE4 mids are similarly tuned as u12t’s but both the peaks are a bit early making them warmer and quite relaxed.
Treble: ExE Gaea > NE4 > CA ARA > U12T> Mest Mk2 . The treble presentation is quite good in this iem but not as good as Gaea due to its tuning. But, Gaea sometimes feels a bit harsh to quite a lot of people due to this. The NE4 treble feels perfect.
Conclusion: These Iem have a very steep asking price. But if you ask me, I would definitely say that these are well worth it. One cannot listen to these crazy technical and lean sounding iems for extended amount of time it’s quite fatiguing. Whereas, that is what is unique about this set its quite non fatiguing not only that but it is fit and comfort is so good that it makes you feel like they aren’t in your ears at all. All these factors lead them to become my daily drivers.

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.
