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.\n\n\nPlays High-Resolution Music up to PCM 384kHz and DSD256\nThe 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.\n\n\nSilver-Plated 8-Core Cable for Smooth, Noise-Free Audio\nThe 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.\n\n\nTough Metal USB Connector Built to Last\nWorried 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.\n\n\nDead-Silent Background with Ultra-Low Noise\nThe 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.
