1400mW Power Output

Under a 32-ohm load, the K11 is capable of pushing 1400mW under balance modes. This allows it to easily drive many Hi-Fi earphones and headphones to fully unlock their potential.

Gain Levels and Volume Curves

The K11 has three separate gain levels, each with its own volume curve. This allows a better listening experience with various types of headphones, whether you are using sensitive earphones or hard-to-drive over-ear headphones.

Audio Circuit and Power Supply

Within the K11’s slim build lies a specially designed audio circuit 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 truly enjoyable music, all of the time.

Slim and Stable

The slim aluminum alloy body allows you to easily place the K11 anywhere, making it easier to complement the rest of your desk. Thanks to the silicone antislip pad, the K11 rests stably and firmly on your table.

One Source of Control

In the K11’s minimalist design, the volume knob acts as a crucial source of total control. The K11’s multifunction volume knob is used to power the device on and off, accessing menu operations, making volume adjustment, and 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.

Driver-Free Mode

The K11 in USB DAC mode does not require a driver on Widows 10 and above. It can also be used with video game consoles such as PS5 and the Switch. Simply plug and play for worry-free usage, whether you are enjoying music or being immersed in games.

RGB Logo Lighting

The FiiO logo on the K11 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 to make the light show elegant.
