Audio46's Opinion
As usual, FiiO is giving you a lot for the price. The K11 not only offers a commendable level of power, but also just makes your music sound audibly better. With an intricate, highly controlled delivery and more spacious imaging, the K11 brings just enough character to your headphone’s sound without manipulating its essence. The only major downside to the K11 is the lack of MQA support. But if you’re not a Tidal streamer, who cares; for $130, the K11 overdelivers in every other way.

Truly balanced. Truly brilliant: Desktop DAC and Headphone Amplifier
- Variety of inputs and outputs
- 1400mW large power output 3 gain levels, 3 volume curves
- Specially-designed audio circuit
- Specially-designed power supply
- Supports 384kHz/32bit, DSD256 Slim build
- Custom LCD screen

A variety of inputs and outputs
On the K11 are USB*, optical, and coaxial inputs* as well as 4.4mm, 6.35mm, RCA line-out, 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
*Coaxial input and output share the same physical connector, Coaxial output can only be used in USB mode
1400mW large power output
Under a 320 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 & Specially-designed 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 on one side, Stable on the other
The slim aluminum alloy body allows you to easily place the K11 anywhere, making it easier to put the device in a way that complements the rest of your desk. Thanks to the silicone anti-slip pad, the K11 rests stably and firmly on your table too.
A beautiful screen full of clarity
A custom, high-contrast, and durable LCD screen* allows you to easily see the sampling rate, volume, gain, or output mode with just a glance.
*Durable LCD screen, always on with no burn-in
Adjustable RGB logo lighting
The FIIO logo is illuminated with RGB lighting, 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.
* Brightness, color, and light patterns are all adjustable using the knob state
One knob, One source of total
In the K11's minimalist design, the volume knob acts as a crucial source of total control. The K11's multi-function volume knob is used to power the device on and off, for menu operation, for volume adjustment, and for other 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.
*LO/PO modes remember the last volume set in each mode independently, no need to readjust the volume when switching between modes
Driver-free mode, Worry-free operation
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 worry-free usage whether you are enjoying music or being immersed in games.
*Installing the driver unlocks support for higher sampling rates
Two elegant colors
- Obsidian black: Understated charm, an earthly beauty
- Midnight silver: Exquisitely elegant, stylishly radiant
