FiiO KA11 USB Dongle DAC and Amp (USB-C, Black)

After spending A LOT of time comparing different DAC's for my IEM's, I settled on the KA11 as it stood out above the rest. Definitely NOT disappointed. It sounds fantastic! Tested both on my PC and my Samsung smartphone, audio is crisp and clear, no distortion, and with a well-tuned EQ it really cannot be beaten. Excellent clarity and depth. I also find it doesn't have a dramatic effect on Smartphone battery life either, which was a concern, though I'm sure that will vary depending on which earbuds/headphones you use. The DAC does get a little warm after a little bit of use, but rest-assured that's totally normal. I will say however, this is a very powerful DAC. It is capable of driving larger headsets without an issue. With that being said, exercise caution if you are using sensitive IEM's (like me). I unfortunately accidentally blasted my ears briefly at 100% volume when I clicked an incorrect button on the PC FiiO app. Worth noting, even with very sensitive IEM's, the noise floor is incredibly low... I hear absolutely zero hiss or artifacts when no music is playing. Incredible. All in all, highly recommended. It blows a lot of the other DAC's at double the price-point out of the water.

This thing just blows my mind, it's just crazy how this thing can produce so much power, it makes any phone sound like a full DJ set up in your pocket ,I have mine connected to an old phone, when I'm sat in the garden or walking the dog, the sound is just Amazing, transform any phone with a USB C connection or purchase the USB to C adapter for penny's, it literally boost ,and turns any phone PC, or gadget literally into a high end HiFi system for not a lot off money, 10 out of 10.

This DAC and amp sounds amazing. The difference compared with many other DACs is night and day. It's actually better than a creative USB sound card I use mostly for 5.1 channel sound. Even when listening to regular Mp3, AAC Vorbis, Opus or other compressed files. I couldn't even turn on the UHQ upscaler with the Samsung DAC dongle but I can with this. But to be fair, I'm now not sure my Samsung DAC dongle was a genuine Samsung product. But I bought that from an Amazon seller as well... This DAC also does DSD. Up to DSD512 oversampling I believe. Cirrus DAC chips like the one this uses are now some of the best. They seem to be making chips as good as Wolfson before Cirrus purchased the company.

Absolutely ridiculous upgrade in sound. I say this after spending ~£5000 in audio equipment from Wharfedale, Denon, SVS, B&W. It does get a little bit hot. But I have no worries since FiiO is an known brand with a good reputation in the budget audiophile community. I'm absolutely certain thermal protection kicks in before temp reaches dangerous levels. 100% must-have for IEMs.

This product has been a disaster. Don’t get me wrong: the sound quality is outstanding, but the reliability is nonexistent. I have had FOUR of them, from Amazon and other retailers, and all have had faults. The first two had a nasty overheating problem, and I mean seriously hot —too hot to touch, and then they would simply cut out. The third had problems with the 3.5mm socket, which didn’t make proper contact with the plug on the headphone cable, resulting in constant dropouts and static. The fourth one has now simply stopped working. The led illuminates, but none of my devices (iPhone 15, Samsung S25, iPad mini, HP Envy, MacBook Air M2) will recognise the dongle. It doesn’t even merit the single star this review requires. Don’t waste your money. Avoid the Fiio KA11

I initially bought the Jade Audio JA1 which is a cheaper version (by Fiio's sub-brand Jade) for using my DT770 Pro 32ohm cans with my phone. That drove them "ok" but i had to have volume close to max. Bought this Fiio KA11 instead as this has a much more powerful op amp inside. These now drive my headphones much harder and i can listen at good volume with still a good 30-40% left -- which means quieter stuff can be boosted Great build quality. Gets a little warm but that's pretty normal when pushing this much power so nothing to be alarmed about -- it's warm not hot. For the price -- great bit of kit

EDITED REVIEW: After using this with my iPhone (review below) I decided to try it with three different DAPs. I ended up returning the KA11 as soon as I realised just how flaky this is. It either won't work at all, or it will only work with certain music players, or it will work and then disconnect and not reconnect... I've installed the Fiio app to see if that helps, but no. Yes, it works with my iPhone, but what if I decide to switch to Android when it's time for a change? And why shouldn't I be able to use it with my DAP as well? It seems like I am not the only person to have these problems. ORIGINAL REVIEW: I used this with an iPhone 15 Pro Max, and Letshuoer IEMs. Compared to the regular dongle I've been using the volume is increased, and the music sounds "fuller". Without the Fiio it's flat and lifeless (XTCs The Mayor Of Simpleton for instance) and it comes to life when the Fiio is substituted. That's not very scientific, I know, but it's accurate.

So far i've had a 8 hour music session with my Beyerdynamic 770 pro X and it drives them well, past safe listening volumes. You will find a lot of people on reddit and reviews saying it heats up a lot, but after 8 hours the hottest it's gotten is on par with a fast charging USB C cable. Have yet to try it on my phone or with their app/software but it's pretty much plug and play on windows 10. Worth every penny if it holds up over time. Oh it also works fine plugged into a USB C female to USB A male adapter, no audible "noise". It's amazing how they've gotten such performance out of a dongle that is almost the same size as an apple adapter.

Le FiiO KA11 est un petit DAC très puissant avec un son propre et détaillé, même sur des IEM sensibles (testé avec les Sgor Adonis). Pour 35 € à l’achat, c’est un excellent rapport qualité-prix. Je le recommande sans hésiter à ceux qui cherchent un DAC compact et performant. Brancher sur ma PS4 pro avec casque HyperX Cloud Alpha fonctionne parfaitement 👍.

Impressive sound for such a small and affordable dongle. My HiFiMAN R10D sounds surprisingly good with it. The HE1000, being more demanding, is less convincing. So far, great value for the price. Time will tell how it holds up in terms of durability.

100% recomendado, la calidad de audio superó mis expectativas, la calidad de los materiales son excelentes, se calienta un poco pero en lo personal no me incomoda y tiene un amplificador potente.

Merhaba, ben Kolombiyalıyım ve bu ürün mükemmeldi.

Excelente producto, DAC que evita restricciones de audio de las capas de personalización de Android y amplificador de excepcional calidad de Audio
