FiiOKA11 USB Dongle DAC and Amp (USB-C, Black)

Excellent bit of kit. Improves the sound through my AKG K240 and Beyer Dynamic DT990s by a great deal vs cheap phone socket outputs and other devices. Of course there are better DACs out there - for more money -, but if you need something low cost and pocketably small, you won't go wrong with this.

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.

Failed after less than 2 months.

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 boostedGreat 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

Really great sound and improves the loudness of your phone dramatically. Unfortunately the bendy flimsy design did not last very long and mine broke within months. Sent it back for a full refund.

For most this will be enough - amazing price - great build quality and great sound.

This thing is an absolute steal at the price... Well done fiio.Powerful outputGreat soundSleek and minimalist designValue

Sent my unit backAfter upgrading the fw to 0.08 stopped working.Openned a ticket and the support sent me a new one for free with 0.08 pre installed and never works on my phone, fiddled with a lot of power/usb options in settings and it doesn't work.Any other dac Inuse in my phone works perfectly.Reddit is full of users wirh this issues too.Seems that fiio is more interested in creating eWaste than actually correct their products and guarantee support for them, or just uave them to work.This was my last fiio product, very disappointed.Not recommended
