FiiO JM21 Portable Hi-Res Lossless Music Player

World’s First Snapdragon 680 Portable HiFi Player

Experience a new standard of speed and efficiency. The JM21 is powered by the Qualcomm Snapdragon 680, built on a cutting-edge 6nm process. Featuring an 8-core Kryo 265 architecture with clock speeds reaching 2.4GHz, this processor delivers a significant performance boost. The result is a device that offers lightning-fast responsiveness and lower power consumption for a truly seamless user experience.

Custom Android 13 Open-Source System

Take full control of your audio library with a deeply customized Android 13 platform. This open-source system is optimized for smooth, effortless navigation, giving you the freedom to install your favorite streaming services like Spotify, Apple Music, and more. It’s a familiar smartphone-like interface tailored specifically for the high-fidelity listener.

Dual Flagship DACs with Powerful 700mW Output

At the heart of the JM21 lies a fully balanced audio architecture. It utilizes dual flagship Cirrus Logic CS43198 DACs paired with two high-performance SGM8262 operational amplifiers. This audiophile-grade circuitry produces a massive balanced output of $700\text{mW} + 700\text{mW}$. Whether you are using sensitive in-ear monitors or demanding over-ear headphones, the JM21 drives them with absolute ease and authority.

Ultra-Portable Design and All-Day Battery

Designed for life on the move, the JM21 is just 13mm thin and weighs a mere 156g. Its ergonomic build offers a comfortable one-handed grip that won't strain your hand during long sessions. Despite its slim profile, it boasts an impressive 12.5-hour battery life, ensuring your soundtrack stays with you from morning until night without the need for a recharge.

Self-Developed DAPS Digital Audio Purification

To ensure sonic purity, the JM21 features the self-developed DAPS (Digital Audio Purification System). By combining a fifth-generation FPGA with custom dual femtosecond crystal oscillators, the device bypasses Android's internal sample rate conversion. This ensures that local playback and third-party apps—including FiiO Music and Apple Music—maintain their original sampling rates for a bit-perfect, lossless listening experience.
