1.FIIO KA11 REVIEW
Today, I can confidently say that among the 3.5mm output dongles I’ve tested, the KA11 provides the best sense of performance. Considering other factors like build quality, design, and more, it ranks at the top in terms of cost-effectiveness. It’s certainly not perfect, but honestly, starting the hobby and being able to enjoy equipment like this, there’s nothing to complain about, it’s going to be the definitive dongle for a lot of people. Not long ago, I recommended the iFi GO link as an entry-level choice, but now I believe the FiiO KA11 has taken its place.

2.Fiio KA11 review: This $29 USB DAC is the best way to upgrade your phone audio
Fiio did it once again with the KA11. The entry-level USB DAC has a metal chassis and excellent build quality, and it delivers 245mW of power at 16Ω — more than anything else in this segment. You get a neutral sound that's great, the DAC drives demanding IEMs with ease, and the tiny size means you can take it anywhere. The best part? It costs just $29.

3.FIIO's Budget Offering
Is the KA11 worth it?
To be honest for its asking price...
Yeah I can recommend the KA11, it offers better audio than your smartphone audio with minimum battery consumption, compact size, and somewhat affordable price.
Its like breathing a new life to your basic smartphone audio.

4.Fiio KA11 DAC Review : Entry-Level Monster
I thank Fiio for this opportunity. The only real lack of the Fiio KA11 is the lack of the USB adapter; for the moment, it is an unrivaled entry level.

5.Fiio KA11 dongle.
Anyway, the KA11 is a warmish dongle with note weight on the slightly thicker side, treble extension is still good. Very decent technicalities for the $29 USD asking price (I bought this from Aliexpress BTW).
So on testing one of the hardest to drive IEMs (Final E5000 at 93 dB/mW sensitivity), I am surprised that the KA11 can drive it to adequate dynamics, with a relatively textured bass. Definitely desktop grade sources will do a better job, but some way pricier portable sources are not able to drive it, with the E5000 sounding one-noted and flabby in the bass as such.
