Couldn't have been happier with this. I needed something portable to drive IEMs and some full sized headphones for an office setup and this does it with ease. The improvement over native device (laptop in my case) is day vs night. I currently own 2 other DACs and have had many other DACs ranging from $100-$1000. I'd rate the KA3's performance somewhere in between that spectrum. Because of the newer chip, it easily crushes the previous DACs I've owned in the $100-$200 range. There is simply more detail here. The dongle is obviously not meant for hard to drive full sized headphones but it is sufficient for something like my Grado RS1x which are quite efficient. Fiio has always been incredible in terms of value and I doubt there is anything else on the market with this ... MoreCouldn't have been happier with this.

For the size and price I was not expecting this.I have other DAC which uses same Sabre chip with 3 times price. but this one much better. I believe its not DAC chip but how you implement DAC chip matters.Coming to sound quality, first thing you will notice its powerful enough for any IEM.Sound signature is neutral and extension is really good with excellent Detail retrieval. You can feel 3D. so its not just left and right you hearing but height and depth when paired with good IEM (I use Pinnacle P1).With Fiio Android App you can control Gain and impedance.A great DAC for the price, and cables are detachable which is also a big plus. 4.4 Balanced output for an additional bonus.Only downside I found is it heats up quickly. After 30 min you can do barbeque on it. ... MoreFor the size and price I was not expecting this.I have other DAC which uses same Sabre chip with 3 times price. but this one much better.

I got this DAC with not many expectations, just wanted to try out a DAC which is relatively well known and has no degrading components. First time listening, it was more loud at the same volume and the sound felt "richer" on my Blon BL03. Played some music on Spotify premium and Poweramp with USB DAC as output. Did not try UAPP app. As this is a warm IEM, the KA3 introduced some clarity in the vocals, bass was less bloomy. These were the things I noticed immediately. I did not actively try to listen for micro nuances so as to stay away from placebo :D. Finally, I didn't notice much battery drain on phone and did not connect to PD type C port as the DAC would get hot. I also did not use the FiiO control app much.

Great Portable AMP/DAC
7 November 2022

I am sharing my experience after using it for more than 6 months. This little dongle is great, has enough power to drive my Sundara/Deva's on SE as well. Though I mainly use this to drive my HD560s and SRH 1540's whenever I go for a walk or Just casually chilling out in the Balcony. This sounds good to my ears when compared to Apple Dongle/MB. The differences is not much, But overall music listening experience with this little portable partner is good. Since sound Impressions are subjective, YMMV. I mainly bought it for On-the-go usage as I have DX3 Pro+ at my desk. It fulfills that Purpose.Only thing to keep in mind is, since it doesn't have an Inbuilt battery, this will consume the power from the Phone or PC wherever connected which might affect the battery ... MoreI am sharing my experience after using it for more than 6 months.

Great beginners dongle DAC.
2 February 2022

Delivery was super quick. Packaging was small and adequate. Offers a fairly neutral sound signature. Very versatile with loads of IEM and headphones. Better to pair with neutral to neutral bright sounding IEMs (brighter stuff sure, but nothing overtly warm). Power is sufficient for most IEMs except really power hungry ones. Build quality is functional and can a beating (black tape because I don't want keys to scratch it.).Customization is excellent for a dongle DAC at this price point. It's a five star product for sure, but the firmware is holding it back. You can only change settings in Android (what about desktop or apple users FiiO?). Impedance settings is reversed in current firmware (v2.0) and windows users might face some intermittent pause during ... MoreDelivery was super quick. Packaging was small and adequate.

FiiO being a company who regularly listens to feedback from users, will iron out these issues with future firmware updates. But those who evaluate a product in its current state should take note...Oh, and there are no hardware buttons :(Tested with: Tin T2, ATH-m40x, RHA MA390 & Sony MDR MA300.

Its setting new benchmarksThe 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 ... MoreOn Thursday i recived Fiio KA3...Before buying i have read almost every review i found on internet about 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 differenceI 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 allSlight improvement in instruments sepration but not what i heardAnd worst porblem is after 5 to 7 min it automatically disconnected in my phone .... Their is good chance its my phones problemThe 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 60Now 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 futureAnd 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 theirBuilt quality is great ... Its very small i have taken photos with sharpner to compare

When i opened the box with excitement, I saw black beauty with nice golden yellow Hi-res icon. Its really beautiful and looks powerful DAC. But when I connected it to my Vivo X70 Pro+ mobile it was not recognized. I was disappointed and was about to return. Last time same thing happened with Shanling UA3 DAC. Finally i returned it.I kept trying using various permutation using FiiO music player app, FiiO control app and trying to make it recognizable. But no help. Finally I tried different way. First I attached USB type C cable came with the KA3 to my Vivo phone and then attached KA3 to the other end and to my surprise the blue LED lit up this time and KA3 has shaken hands with my Vivo phone.

The little device has grown on me
10 May 2022

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 ... MoreThough 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.

Highly recommended.

Value for money
19 September 2022

Using it for last 10 days and found that it is a really good addition to your beginner audiophile setup.Soundstage gets more extended, and separation can be felt very clearly. Overall response of DAC-Amp is neutral. Lows are more in control, mids are untouched and highs get more transparent.Device gets warm after 5-10 mins usage, but its normal and not to worry.I only felt that there should be some kind of dedicated Fiio software/application for more control to make it versatile for any IEM/headphone. Also, headphone correction curves would be added benefit.

Wanna use good wired(maybe even balanced) headphones/IEMs with mobile?
1 June 2023

Hey There, if you are one of those who wants to use a good pair of headphones such as Sennheiser 600 series or Beyerdynamics or some good balanced In Ear Monitors and use 'em on the move, then you need a good quality portable DAC and AMP.
