I have reviewed this product above ... Where i was realy disappointed by the sound quality of it ...but after 3 4 days of usage i suspect sumtime it sounds really different and good .................. After lot of experiment i found out that inbuilt Dolby Atmos was messing with the sound quality all the time i was using costume rom so it might be broking something so i change rom and what a change in audio quality.....
This is purly awesome DAC ... The details are absolutely finominal and really fast even when using 320kbps songs i got surprised ...


I would like to apologise for the initial review i gave without completely understanding and using the product

I am looking forwod to buy a beter IEM to get best of it .
Thankyou headphone zone .


And yes an Awesome product needs Awesome photoshut

On Thursday i recived Fiio KA3...
Before buying i have read almost every review i found on internet about it ... (Their isn't much about KA3) , watched every video on internet including Japanese and chainese langvage (by taking screenshot of every subtitles and translet with google lens )
I interact with lot people on YouTube....
Also talked with headphone guru lan pereira ...

Lot of them from YouTube and online review were clamming that it sounds really good better than my 18k DAC and 15k DAC ... Its setting new benchmarks
The sound is crisp clear and so much detailed....
Soundstage is awesome and every IEM sound great with it .....

I didn't find much of this ....

(What i am gona say now is on the basis of what i experienced i have only one IEM that's KZ ZSN pro X brought from headphonezone and my source is rooted Android i have good amount of FLAC , WAV , AAC LC files some DSD too ...and i use them daily so i will easily notice if thier is a change )

As soon as i started using it ... I feel like, its the same sound not any difference ... Then i update the firmware of KA3 to 2.0 and didnt notice much ....
Their is slightly (very slight ) improvement in details but it dosent makes difference... My phones bloody internal ordinary DAC give almost 95% of same details i was using POWERAMP ... I i switch to UAPP ...and it still didnt make much difference
I tried DSD files ... In native DSD mode ...
And playing them from PowerAmp without DAC was almost same they played as DoP (digital to pcm)in PowerAmp ...
Another drawback is the same soundstage ....
My phone gives the same soundstage not any improvement at all

Slight improvement in instruments sepration but not what i heard

And worst porblem is after 5 to 7 min it automatically disconnected in my phone .... Their is good chance its my phones problem

The only thing what is good is amplification ... It gives a lot amplification which i dont need i was allready using my IEM bilow 45_50 i rarely go 60
Now with dac i go 12-16 ....

I am willing to return but according to headphonezone policy i won't get refund i have to buy something yels ... Which i cant now .... So i am gona keep it ...
What other options do i have ...
I hope my initial experience will prove wrong in future
And with my other IEM , or with another firmware upgrade the KA3 will satisfy my expectations ...

I havent tried it with balanced output , i hope it might sounds good their

Built quality is great ... Its very small i have taken photos with sharpner to compare

Considering the price of the it, it's the cheapest 4.4 mm dongle and it performs pretty good. Decent width, tightens bass, amazing detail retrieval. After a while of usage it has quite grown on me. Build quality is decent and overall size is pretty compact too !!

It's good adaptor but it only works great Android.
When connected to windows the audio drops for 1 sec every half a minute.
I have upgraded the firmware and also Installed drivers from official sources.
I tried usb 2 , usb 3 and even type c port but the problem is same.
Hope Fiio resolve this issue in firmware upgrade or else this is waste of money.

I am an audiophile! I discovered it when I first listened to music on my friend's Sony W700i, and I wanted only this phone and nothing else. My first smartphone was Sony Walkman as well. Once Sony stopped producing Music centric phones, LG stepped in with its quad DAC phones. My LG G7 ThinQ was a music beast. Unfortunately, I dropped it, and I don't know if the service center guys can fix it. In my search for a music-centric phone, I was only disappointed, as I found none that can match my LG phone. And LG stopped making phones, Sony stopped selling phones. After a lot of research, I discovered dongle DACs can be good alternatives. Also, after a lot of research, I zeroed in on KA3. I am not disappointed. When I first listened to music using KA3, it not only matched but exceeded what my LG phone could pull off. I am satisfied.

I bought KA3 and tested on different IEMs like my Moondrop Starfields a nd Tin Hifi T3 Plus.
It sounds great and it powers them without any difficulty.
Love it.

Though I haven't used the device a lot (got outdone by time), the device managed to impress me further over the last month.
First, I upgraded the firmware to 2.0 - the process is a bit quirky, but worked fine. I allowed some burn in time as well.
I also installed the FIIO Control app on my Samsung A73. The high impedance setting in the app does enable you to drive some power hungry headphones. The device really shines on a Windows PC though. It has insane power for such a small device. Even power hungry IEMs get uncomfortably loud at 6 - 8 points (on a scale of 100). Once again, don't expect it to drive full size 250 ohms and above headphones to their *full* potential. But it should be enough for a casual listen.
To give a comparison, Samsung's own type C to 3.5 mm adapter needs to be set at 50 points to sufficient power low power IEMs. To be fair, Samsung consumes less than half as much power as KA3.
The bottom line - KA3 is indeed one gem of a device with upgraded software and shines in nearly every scenario. Highly recommended.
