Desktop Decoding Headphone Power Amplifier

The K11 offers a variety of input and output options, including USB, optical, and coaxial inputs, as well as 4.4mm, 6.35mm, RCA, and coaxial outputs. With these diverse connectivity choices, it ensures flexibility for a wide range of audio setups. Whether connecting to a PC, gaming console, or other audio devices, the K11's multi-input design gives you full compatibility and convenience. Coupled with a 1400mW power output, it can easily drive a wide range of Hi-Fi earphones and headphones, unlocking their full potential.

Exceptional Audio Performance with Custom Circuit Design

Inside the K11, you'll find a specially-designed audio circuit built for stable and high-quality sound. Powered by an external 12V switching power supply and more than 16 low-noise LDOs (Low Dropout Regulators), this setup ensures precise voltage stabilization, resulting in a cleaner and more robust power supply. This ultimately leads to high-quality, enjoyable audio. Additionally, the K11 features three gain levels and three distinct volume curves, making it highly adaptable for headphones with different impedances. This flexibility helps you get the most out of both sensitive earphones and high-impedance headphones, improving the overall listening experience.

Slim Build with High-Contrast LCD Screen and Adjustable RGB Lighting

The K11 boasts a sleek and slim aluminum build, making it a perfect fit for your desktop without taking up too much space. Its high-contrast custom LCD screen provides clear visibility of essential information such as the sampling rate, volume level, and output mode. The screen ensures you can easily monitor the current settings at a glance. Additionally, the RGB lighting around the FIIO logo is fully adjustable, allowing you to change the brightness, color, and light patterns to suit your personal preference. The design is both functional and elegant, bringing a touch of sophistication to your setup.

One Multifunction Knob for Easy Operation

The K11's minimalist design includes a multi-function knob that controls all essential operations, including volume adjustment, power on/off, menu navigation, and more. With the ability to quickly switch between output modes (LO/PO) and adjust settings by simply pressing or turning the knob, this simple yet intuitive control system ensures smooth and hassle-free usage. The K11 also features driver-free USB DAC mode, making it plug-and-play on Windows 10 and higher systems, as well as with gaming consoles like the PS5 and Nintendo Switch. This means you can enjoy high-quality audio without needing additional drivers or software installations.

Elegant Color Options to Match Your Style

The K11 is available in two refined color options: Obsidian Black, which exudes understated charm, and Midnight Silver, which offers an exquisitely elegant look. Both colors complement the sleek design and high-end performance of the K11, adding a touch of style to your desk while offering excellent sound quality.
