FiiO has officially unveiled the JM21 Portable High-Resolution Lossless Music Player, bringing flagship audio architecture to an entry-level price point. At its core is a 6nm Qualcomm Snapdragon 680 octa-core processor, delivering smoother performance with lower power consumption, paired with Android 13 for a modern, app-friendly experience.<\/p>\n

\"\"<\/p>\n

Despite packing serious hardware, the JM21 maintains an impressively slim 13mm aluminium body, weighs just 156g, and features a 4.7-inch HD display, making it an ideal one-handed portable companion for audiophiles on the move.<\/p>\n

\"\"<\/p>\n

Sound quality is where the JM21 truly shines. It features a fully balanced audio design built around dual Cirrus Logic CS43198 flagship DACs and dual SGM8262 op-amps, supported by a meticulously engineered segmented power supply and shielded internal partitions to reduce interference. The result is a powerful and clean output of up to 700mW + 700mW via the 4.4mm balanced output, easily driving everything from sensitive IEMs to demanding over-ear headphones. Users can further tailor performance with three gain levels and three independent volume curves, ensuring optimal control across different headphone types.<\/p>\n

\"\"<\/p>\n

\"\"<\/p>\n

The JM21 also debuts FiiO\u2019s Proprietary DAPS (Digital Audio Purification System), powered by a 5th-generation FPGA and dual custom femtosecond crystal oscillators with ultra-low phase noise. This setup eliminates global SRC interference, preserving the original sampling rate whether you\u2019re playing local files, streaming from third-party apps like Apple Music, or outputting audio to an external DAC via USB or SPDIF. High-resolution support is extensive, with local decoding up to 384kHz\/32bit and DSD256, and USB audio reaching 768kHz\/32bit and DSD512.<\/p>\n

\"\"<\/p>\n

Designed for all-day listening, the JM21 offers up to 16 hours of battery life (single-ended output on the 4GB+64GB model), alongside fast charging via USB-C. Connectivity is equally versatile, with two-way Bluetooth 5.0 supporting LDAC, aptX HD, LHDC, and more, plus asynchronous USB DAC functionality for use with Windows and macOS systems. Add in system-wide 10-band PEQ, dual 3.5mm and 4.4mm outputs, line-out, SPDIF, Wi-Fi streaming, and microSD expansion up to 2TB, and the FiiO JM21 positions itself as a compact yet remarkably complete digital audio player for both newcomers and seasoned audiophiles alike.<\/p>\n
