"For the price, the KA3 seems like a no-brainer for those looking for a simple DAC dongle for their smartphones or laptops. The crisp and meaty midrange is definitely its biggest standout."

"A dongle with fantastic technicalities, an analytical sound but with a lot of power , cleanliness, softness, soundstage, separation, detail and much more."

"It handles sensitive IEMs with finesse, so you don’t need to worry about having enough power or dealing with background noise. Wrap that up in a handsome, rugged body and FiiO has got a winner."

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
We are extremely sorry that the product didn't match your expectations. We appreciate your honest review & ratings, Mukul Kalsait! Soundstage majorly depends on the IEMs/ headphones you use & so we recommend you to try other IEMs & we are sure you will notice a change. We again appreciate your elaborative review which will help others to make an informative decision.
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
HI there, we are so happy you took out time & elaborately reviewed the product with a comparison. We are sure this will help our customers to make an even better & informed decision.
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.
After much deliberation I purchased my first DAC for use with my Apple phone and new Headphones! But my dreams of good listening were dashed when I found out that there is no iOS app for the FIIO KA3! The photos showing the KA3 placed on a Mac and an iphone mislead one into believing it is compatible with these products. Additionally it is not mentioned anywhere in teh device info that the control app is only available for android phones. Without the app there is no way to adjust the settings of the device and through that find out whether the device is really making a difference to my music. I would request Headphone zone to verify such compatibility issues before they post a information of any device on their website.
Service by Headphone Zone was very good! Could track my order every step of the way and received it earlier than expected! Thank you Headphone Zone!!
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 !!
Hey there, nothing makes us happier than knowing you loved your purchase, hope you had a comfortable shopping experience & thank you for the great review & ratings!
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.
Hey, always a delight to hear that our customers are happy with the purchase & it is up to their expectations. Thank you for the review & ratings. Cheers!
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.
