The FiiO Jade Audio Jiezi B is a technically precise, ultra-compact USB-C dongle DAC with an integrated amplifier function, offering excellent sound performance despite its minimal dimensions. It features a high-performance USB bridge chip, a high-quality DAC/ADC component, and a DSP, supporting PCM formats up to 32-bit/384 kHz as well as DSD256 decoding. This results in impressively clean sound reproduction. The integrated 10-band equalizer allows for personalized sound adjustments via the FiiO Control app or web interface, including the ability to save and share custom sound curves. The Jiezi B version utilizes a 4.4 mm output in an unbalanced architecture, with performance comparable to balanced solutions. Measurements indicate a power output of over 49 mW per channel, an extremely low noise level, and an output impedance of under 0.5 ohms. This makes the Jiezi B excellent for sensitive in-ear monitors as well as more powerful portable headphones with a 4.4 mm plug. Even at low volumes, it impresses with finely resolved dynamics and a neutral sound signature. The housing, made from an aluminum-magnesium alloy and adorned with traditional engravings, combines an elegant look with robust feel. The cable is made of oxygen-free, palladium-coated copper and is wrapped in silicone and textile to ensure flexibility and durability. The dongle format with an integrated USB-C cable allows for universal compatibility – plug-and-play with Android, iOS, HarmonyOS, Windows, macOS, and Linux. It operates via UAC 1.0 or 2.0, ensuring extensive system compatibility. The Hi-Res Audio certification further emphasizes the sound quality. Weighing approximately 6 grams and featuring stylish craftsmanship, the Jiezi B combines lightness with audiophile precision.
