It plays through a 3.5mm headphone output or a 4.4mm balanced output, reaching up to 700mW+700mW into 32Ω balanced, and its 4.7-inch HD touchscreen makes browsing and controlling playback straightforward. Bluetooth 5.0 transmits over SBC, AAC, aptX, aptX HD, LHDC, and LDAC, and can also receive audio over SBC, AAC, and LDAC from another source. As a USB DAC it supports up to 384kHz\/32bit and native DSD256 for local playback, or 768kHz\/32bit and DSD512 over USB. The JM21 comes in a 3GB+32GB configuration with up to 12.5 hours of battery life, or a 4GB+64GB configuration with up to 16 hours, and both support microSD expansion up to 2TB. It measures about 120.7 x 68 x 13mm, weighs about 156g, and comes in Black or Sky Blue.\u003c\/p\u003e\u003ch4\u003eSimcoe Audio Video Insight\u003c\/h4\u003e\u003cp\u003eThe JM21 packs genuinely capable dual-DAC hardware and a 4.4mm balanced output into a slim, phone-like body — it's an easy player to live with day to day without feeling like a compromise on sound.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eTwo CS43198 DACs in a fully balanced circuit\u003c\/li\u003e\n\u003cli\u003e4.7-inch HD touchscreen in an ultra-thin body\u003c\/li\u003e\n\u003cli\u003eTwo-way Bluetooth 5.0 with LDAC and aptX HD\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eBest for the FiiO JM21:\u003c\/strong\u003e use the 4+64G configuration's larger storage if you plan to carry a big lossless library without relying on a microSD card.\u003c\/p\u003e\u003ch3\u003eMore Details\u003c\/h3\u003e\u003ch4\u003eWhy It Wins\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTwo CS43198 DACs\u003c\/strong\u003e: Paired with dual SGM8262 op-amps in a fully balanced circuit for a clean signal path.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e4.4mm Balanced Output\u003c\/strong\u003e: Reaches up to 700mW+700mW into 32Ω, well beyond typical slim players.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e4.7-Inch HD Touchscreen\u003c\/strong\u003e: Makes browsing a large library and controlling playback straightforward.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eWhat Makes It Different\u003c\/h4\u003e\u003cp\u003eMany slim digital audio players trade away balanced output or a large screen to stay thin.
