The FiiO JM21 is a state-of-the-art portable Android 13 digital audio player (DAP) that combines flagship-class hardware with a slim form factor. Powered by an 8-core Qualcomm Snapdragon 680 (6 nm), it delivers smooth, lag-free navigation and playback performance. Dual Cirrus Logic CS43198 DAC chips with dual SGM8262 op-amps form a fully balanced audio circuit, ensuring clean, detailed sound with excellent channel separation and dynamic range — whether you listen through the 4.4 mm balanced output or the 3.5 mm single-ended jack.

With up to 700 mW + 700 mW balanced output (32 Ω), the JM21 can drive demanding full-size headphones while maintaining headroom and clarity. The 4.7″ high-definition display and portable 156 g body (only 13 mm thin) make it a versatile player for both on-the-go listening and critical stationary sessions. Expandable storage via microSD (up to 2 TB) and support for high-res PCM & DSD playback make the JM21 a flexible, future-proof music source.
