Flagship-Level Processing and High-End Audio Performance Come Together at an Entry-Level Price in the FiiO JM21 New Octa-core 6nm Snapdragon 680 Fully balanced audio design Integrated with Android 13 Up to 700mW + 700mW output power 13mm ultra-thin body with 4.7-inch HD display 4.4mm + 3.5mm outputs Flagship Chips at an Entry-Level Price At the heart of the JM21 lies Qualcomm’s new Snapdragon 680 processor, an efficient 8-core design built on Kryo 265 architecture, clocked up to 2.4GHz and fabricated on an advanced 6nm process. The result is a clear leap in performance with lower power draw, delivering fast response, fluid navigation, and a consistently smooth listening experience. Powerful Sound A specially-designed and tuned audio circuit allows the JM21 to achieve a balanced power output of up to 700mW + 700mW within an ultra-thin body. This ensures effortless power and control across a wide range of headphones. Three Gain Levels, Three Volume Curves The JM21 has 3 levels of low, medium and high gains, each gain level having its own volume curve. This allows the JM21 to give you a better listening experience with various types of headphones, whether you are using earphones or over-ear headphones.  Dual Flagship CS43198 DACs Two Cirrus Logic flagship CS43198 DACs are paired with two high-performance SGM8262 op-amps in a fully balanced design. FiiO has further optimized the segmented power supply as well as the front and rear stage gain stages for wider dynamic range and enriched musicality.  Segmented Power Supply There are independent power supplies for digital and analog sections. The DAC, voltage and current amplification stages each are handled by a dedicated stage in the three-stage segmented power supply. Each of the op-amps in the four-channel amplification stage is equipped with four independent LDO precision regulators.  Ultra-Long Battery Life The ultra-long battery life, enough for continuous listening for an entire day, ensures you can listen pleasantly without anxiety of running out of power. The single-ended battery life is about 16hrs, and balanced about 12.5hrs.  Asynchronous USB DAC When connected to a MacOS or Windows computer, the JM21 can greatly improve your audio experience with sampling rate support up to 384kHz/32bit. *USB DAC functionality is designed for audio development purpose with slightly higher latency. It is not recommended to watch videos using this mode.
