Dual-Chip Design Delivers Powerful, Clean Sound The JCALLY JM20MAX uses two high-performance chips working together: a Cirrus Logic CS43131 DAC chip and an SGM8262 amplifier chip. This dual-chip setup gives you exceptional driving power and studio-quality sound. Whether you are listening with sensitive earphones or hard-todrive over-ear headphones, the JM20MAX brings out details and dynamics that your phone or laptop’s built-in jack simply cannot. Plays High-Resolution Music up to PCM 384kHz and DSD256 The JM20MAX decodes PCM files up to 32-bit/384kHz and native DSD256 (1-bit 11.2MHz), so your high-resolution music library sounds exactly as the artist intended. Pair it with dedicated music apps like Hiby or Viper, and you will hear a level of clarity and depth that transforms your daily listening. No more compressed, muddy sound – just pure, detailed music. Silver-Plated 8-Core Cable for Smooth, Noise-Free Audio The cable features 8 cores and 392 strands of silver-plated copper, arranged in a spiral design that resists interference and blocks noise. This ensures a clean signal path from your device to your ears. The result is smooth, well-extended highs, sweet and natural midrange, and tight, controlled bass – delivering rich detail and balanced sound across the board. Tough Metal USB Connector Built to Last Worried about dongles breaking or connectors getting loose? The JM20MAX’s USB plug is built like a tank. It uses a 24-pin one-piece tensile shell with gold-plated pins, a high-temperature rubber coil, and a stainless steel housing. It has passed a 24-hour salt spray test and 10,000 plug-unplug cycles – so it resists wear, corrosion, and deformation. This is a dongle that will last. Dead-Silent Background with Ultra-Low Noise The JM20MAX delivers a signal-to-noise ratio greater than 126dB, a dynamic range of 122dB, and crosstalk of -140dB. What does that mean for you? A dead-silent background – no hiss, no static, just pure music. Quiet passages stay quiet, and sudden transients hit cleanly. You will hear the subtle breaths of a vocalist and the decay of a piano note with stunning clarity. Works with 16Ω to 600Ω Headphones, from Earbuds to Studio Cans Thanks to its wide load adaptability, the JM20MAX works with virtually any headphone you own. The 3.5mm output also connects to speakers or your car’s auxiliary input. Just plug it into any Type-C phone, tablet, or computer – no drivers needed. Premium CNC-Carved Aluminium Body with Matte Silver Finish The JM20MAX’s shell is precision-carved from aluminium alloy using CNC machining, then finished with an anodized matte silver spray and 180-mesh fine sandblasting. It looks sleek, feels solid, and resists fingerprints and scratches. At just 6.5 grams and roughly 110mm long, it disappears into your pocket – but the sound it delivers will stay with you all day.
