The HiBy R6Pro II 2025 is the next evolution of HiBy’s acclaimed portable digital audio player (DAP), designed for discerning audiophiles who seek uncompromising fidelity, raw power, and modern versatility. With dual Cirrus Logic CS4308P flagship DACs, switchable Class A/AB amplification, and a 632mW balanced output, this player sets a new standard for Hi-Res portable music players in 2025.
The R6Pro II 2025 debuts the industry’s first dual-chip CS4308P DAC architecture, running twin DACs in parallel for superior sound density, imaging, and micro-detail. Capable of 32-bit/768kHz PCM, DSD512, and MQA 16× decoding, it achieves:
123dB dynamic range
Ultra-low THD+N (-115dB)
A sound signature that is rich, natural, and layered
The result: a lifelike listening experience with breathtaking resolution and holographic soundstage.
HiBy equips the R6Pro II 2025 with dual independent amplifier circuits:
Class A Mode → Ultra-linear, distortion-free power for demanding full-size headphones and multi-driver IEMs.
Class AB Mode → Efficient, cooler operation for daily listening with extended battery life.
With one-touch switching, you can tailor the output to your headphones and preferences.
The 632mW @ 32Ω (4.4mm balanced) output makes this DAP powerful enough to rival desktop amps, delivering:
Faster transients
Deeper bass impact
Wider dynamic swings
Effortless drive for high-impedance headphones
Compared to the previous R6Pro II, the 2025 model doubles down on power and refinement, ensuring every track feels more alive and immersive.
Specially tuned for mid-low frequency richness, the R6Pro II 2025 emphasizes:
Warm, natural mids
Smooth treble with no harshness
Velvety texture in vocals and instruments
This makes it perfect for long listening sessions, balancing reference-grade detail with enjoyable musicality.

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.

Lovely cable. Great physical feel and durable.

It's been 1 year of using this iems and still it works completely fine currently iam using it with a An01 Bluetooth adapter and it's perfect
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.
Great quality and value for money
Great product
Audio is
I am not audiophile but the amount of research I have done to get my first iem ,I mean so much. Kiwi ears Cadenza just blew me away with it's music 🎶 😍❤️🔥.I have used Oppo enco buds 2 , Samsung galaxy buds live, Realme buds 2 , after hearing both wireless , wired connection , These iem just gave me so much clarity in every songs like I'm hearing them for the first time in my life . If you have 3k or 3.5k I mean the price can vary time to time ,just buy them ,you won't regret it ✨️
Now let me say about somethings you have to look ,then you can hear the best music .
1st - The eartips provided in the box ,for me the white ones are crystal clear ,The full black ones are like music is happening in the back of the head ,I mean nothing is in the forward and the black red ones are bassy calm ones ,they will make your ears boomy ,the thump is there🤩🔥✨️ But my favourite is white ones❤️🔥I like flat crystal clear music ❤️
Next get yourself a 3.5mm dac ,it will enrich your music listening and give power to your iem.
Now another important thing ,download the song in lossless format like Flac or Wav for mesmerizing details in songs and no crackling or distortion in songs or hear music in apple music with monthly subscription .Let me tell you every songs is not hi res ,so don't worry about no seeing hi res or lossless mark in song section but try to hear or download them in pure form .
My iem journey today starts with kiwi ears Cadenza ( it is in burningstage ,if any problem arrive I will update✌🏻), It is a rabbit hole, so much to know about eartips, cables, drivers ,Eq so much more .Whoever read this to the last ,thank you & best of luck your iem journey for future, Have a great life ❤️✨️🫶🏻 Thank you The AudioStore❤️🔥❤️🔥
Quality One of the Best...
