Product Description
FIIO K11 Compact Desktop DAC and Headphone Amplifier
A variety of inputs and outputs
On the K11 are USB*, optical and coaxial inputs as well as 4.4mm, 6.35mm, RCA line, and coaxial outputs*. Having more inputs and outputs than other typical entry-level amps means the K11 is more than capable of meeting your needs of putting together a capable audio setup.
*USB connection to phones for decoding does not consume the phone’s battery
*Coaxal input and output share the same physical connector, Coaxal output can only be used in USB mode
Large power output
Under a 32Ω load, the K11 is capable of pushing 1400mW under balance modes. This allows it to easily drive many HiFi earphones and headphones to fully unlock their potential.
3 gain levels, 3 volume curves
The K11 has 3 separate gain levels, each gain level having its own volume curve. This allows the K11 to give you a better listening experience with various types of headphones, whether you are using sensitive earphones or harder-to-drive over-ear headphones.
Specially designed audio circuit and power supply
Within the K11’s slim build lies a specially designed audio circuit designed for great sound quality. This is backed by more than 16 low-noise LDOs for precise voltage stabilization and powered by an external 12V switching power supply. All of this leads to a purer and more robust supply of power, leading to stable high-quality audio and thus truly enjoyable music all of the time.
Slim and stable
The slim aluminium alloy body allows you to easily place the K11 anywhere, making it easier to put the device in a way that compliments the rest of your desk. Thanks to the silicon anti-slip pad, the K11 rests stably and firmly on your table too.
Clear always-on display
A custom, high-contrast and durable VA display allows you to easily see the sampling rate, volume, gain, or output mode with just a glance.
Adjustable RGB logo lightning
The FiiO logo is illuminated with RGB lightning, giving you a quick way to identify the sampling rate of the current audio being played back. Six LED strips work in conjunction with a carefully placed reflective film and parts of the body designed to reflect light to make the light show uniform and elegant.
One multifunction volume knob
In the K11’s minimalist design, the volume knob acts as a critical source of control. The K11’s multifunction volume knob is used to power the device on and off, for menu operation, for volume adjustment, and for functions. The knob is designed so that you can quickly execute various complex actions by simply pressing and turning the knob. You can also quickly switch between LO/PO modes by double-pressing the knob, making it easier for you to appropriately connect to different headphones or audio setups.
Driver-free mode for plug-and-play
The K11 used in USB DAC mode does not require a driver on Windows 10 and above systems, and can also be used with video game consoles such as the PS5 and the Switch. Simply plug and play for easy usage whether you are enjoying music or being immersed in games. Driver is available to install for support of higher sampling rates.
Revitalize your television or computer with this incredible decoder, and experience a whole new level of sound. Whether you’re at home or in the office, paired with speakers or headphones, you’ll be able to enjoy delightful and captivating music.

Audiophile quality conversion and reproduction
These are absolutely spot on for audiophile quality conversion and reproduction. So good I bought two. Can’t recommend them highly enough.

Overall a good purchase
Good, high quality. Sound it more powerful and punchy. Doesn’t take up too much room, good settings for the onboard RGB as well! Good weight, suitable for a desk. Good value for money and very easy to setup, albeit poor instructions.

exceptional quality for the price with a few problems
I like this amp as it has clear crisp audio with a decent balanced power output. Hard to find anything better for the price rn. Unfortunately there is some problems.Someone on here said you cant turn it off which is wrong you just have to hold the one button that is on it down for like 10 seconds but anyways my problem with this is that at certain frequencies the audio cuts out completely.(UPDATE BELOW) At first I noticed this problem on Tidal when playing certain songs and I just thought that it was tidal making this problem not the amp. For the first time today I experienced the audio cutting out whilst watching the movie dune on Netflix so it is the amp… I’ve tried different cables etc, its for sure the amp causing the issue. It does rarely happen when watching movies and is more common when listening to music but this is kinda unacceptable really… An amp that cuts out certain frequencies completely? Also the Fio website sucks, I tried to update my drivers for the amp and it literally doesn’t work. Maybe for others who really want to go out of their way to get the update to work might be able to get it to work but it shouldn’t be this f difficult. Also the windows volume bar doesn’t work when plugging the amp in but idc.UPDATE. I figured out that this problem with the audio cutting out only happens when changing sample rate settings in the sound control panel for the amp. So the problem is when playing at a sample rate of 352800 khz and above. When using the 192k sample rate and below I haven’t run into any problems yet but I’m not going to lie this is still unacceptable. Obviously people are going to want to run this thing at its full potential but this isn’t possible without problems unfortunately so buy this if you’re happy with 192khz sampling rate, don’t expect the 384khz to fully work as it just cuts out sometimes. Hella annoying that nobody else has shared this info online so far I’m literally the only one aware of this that has posted this info so you’re welcome Fio you useless donuts

Excellent budget dac/hdp-amp but set up beware
Before forming your opinion, change the default digital filter from 3 to 6. Where 6 is no oversampling and has less harshness compared to 3 which made sibilance more noticeable.Some have stated filters 1 or 2 are also better sounding but 3 is the worst for me.Power, resolution and features are great for the price. I had been using Chord Mojo (1st iteration) fed by HiBy R5 and Sennheiser HD560s, but the Mojo is bettered by this. Not yet tried the balanced output.Small, stylish and easy to operate. Must run off mains power with supplied adapter but I prefer this.

A lovely dac, shiny UI, upgraded from the old K3
I got the K11. Had problems getting my windows 11 box to see it. It would see it for a second, then say it was disconnected. Fixed by rebooting windowsI upgraded the fw from 1.05 to 1.14, had to rename the folder to take out chinese characters, else it simply exited when I loaded fw hex file.It sounds much better than the K3, to me, more detail, more everything, tracks that sounded really good on K3+HD599 sound even better on the K11.Money well spent. Look online for reviews, not amazon, you’ll see that they are glowing

This is great, I’ve been trying a few different amps and dac combos in the price range of £100 ish and this is what I landed on in the end. I don’t think you can actually beat this for £120, the sound signature is very neutral and doesn’t seem to colour your sound at all which is ideal if you’ve got headphones with strong signatures. I have flat magnet HE400se headphones that I EQ with software and they sound incredibly smooth and clear through this. Make sure you update the firmware properly if you use it on Pc.

Le FIIO K11 est une vraie réussite ! Ce DAC/ampli offre un son clair, puissant et précis, avec une excellente dynamique. La prise en charge du DSD256 et du 384 kHz/24 bits permet de redécouvrir ses morceaux préférés avec un niveau de détail impressionnant.Les multiples sorties (6,35 mm, 4,4 mm, RCA, coaxial, optique) rendent ce petit boîtier ultra polyvalent, parfait pour un usage sur PC, Mac ou système audio domestique. La puissance de sortie est largement suffisante pour driver des casques exigeants.La finition noire est sobre et élégante, et la prise en main est simple, même pour les non-initiés. Rapport qualité-prix imbattable dans cette gamme ! Je recommande chaudement aux audiophiles comme aux utilisateurs en quête de meilleur son au bureau

I am running as a DAC/headphone amplifier for a Bluesound streamer via the optical connector.I have a pair of Audeze LCD-2 headphones which are tough to drive and for which I have upgraded to a 4.4mm balanced cable.The FIIO K11 drives the big Audezes with ease and the combination sounds great – detailed with clear, deep bass, clear midrange and nice high frequency definition without sounding shrill or sibilant.The menus are very easy to navigate – I migrated from a Chord Mojo2 which was a nightmare with all its coloured LEDs (it eventually died and I have not got round to getting it fixed yet).I am very happy with the FIIO K11 and would recommend it strongly. For the price it is an absolute steal!

I wanted to get into higher end audio, namely by finding a desktop DAC with balanced audio output. For under $150, this was an incredibly sensible purchase for my needs. Unit itself is made of solid material, sleek black finish that isn’t a total fingerprint magnet, with full size audio out as well as the aforementioned 4.4mm balanced out. My headphones ROAR out of that balanced out, even on low amplification! Love the aesthetics from the LED lighting on top, which I didn’t even realize was a feature when I plugged it in! Pairs great with a room and setup full of RGB. If you want to get into upper mid to higher end audio, this is a fantastic starting point that’ll run out of any desktop or laptop, or even game console with no drivers needed! Drivers are necessary for ASIO out on desktops though, which can be tricky to install. Overall though, great value and sound, these make your headphones even better.

Perfect for my hd560s

My Wiim Ultra had an iffy headphone output so I bypassed it with this puppy, using the USB port. My modest headphones sound better than ever! I am very happy with this unit as it also has optical and coax inputs, if needed. It has 3 settings for various types of headphones. The default “medium” setting works great with my headphones so I left it. But it can also work with headphones that need more juice, I guess. Anyway, I am a happy guy!
