JCALLY JM6PRO II
Revolutionary Dual-Chip Architecture with Visual Identity
The JCALLY JM6PRO II represents a comprehensive evolution from the acclaimed JM6PRO, introducing a visible window design that showcases the internal DAC and amplifier chips. At its core, the Conexant CX31993 flagship DAC chip pairs with the Maxim MAX97220 secondary op-amp chip. This dual-core configuration unlocks the explosive potential of the DAC, delivering a leap in sound quality characterized by powerful resolution, expressive dynamics, and an immersive, natural soundstage.
High-Power Output for Demanding Transducers
The JM6PRO II delivers a substantial 70mW output power at 32Ω (THD+N <1%), an 18% improvement over conventional dual-chip implementations. This increased output effortlessly drives high-impedance earphones and headphones, ensuring stable, high-quality sound across a wide impedance range—from 16Ω to 300Ω. Whether paired with sensitive in-ear monitors or demanding over-ear headphones, the JM6PRO II provides authoritative dynamics and precise control.
Ultra-Low Loss Circuitry for Pure Fidelity
Engineered with an ultra-low-loss design, the JM6PRO II achieves industry-leading objective performance metrics. The signal-to-noise ratio reaches approximately 107dB (32Ω, A-weighted), while background noise is minimized to just 5.7μV—5% lower than competing solutions. Total harmonic distortion plus noise (THD+N) measures an exceptional 0.0030% at 32Ω, a 57% reduction that eliminates coloration and interference to reveal the true texture of original recordings. Crosstalk is suppressed to -71dB, ensuring superior spatial perception and precise instrument localization.
Impeccable Impedance Control and High SINAD
With an output impedance of only 0.2Ω at 32Ω—a 91% reduction compared to typical designs—the JM6PRO II complies with the industry standard recommendation that amplifier output impedance should be ≤1/8 of headphone impedance. This ensures broad headphone compatibility and stable audio performance across virtually all earphone types. The SINAD (signal-to-noise-and-distortion) ratio reaches approximately 90dB, a 9.7% improvement that results in cleaner sound quality and higher fidelity, faithfully reproducing your music without added coloration.
Premium 8-Strand 448-Core Silver-Copper Hybrid Cable
The JM6PRO II employs an 8-core, 448-strand silver-copper hybrid conductor cable featuring ultra-low dielectric loss and optimized characteristic impedance. This advanced cable construction preserves square wave signal integrity during digital audio transmission, significantly reducing jitter and improving decoding accuracy. The result is that audio signals are processed with unprecedented precision, reproducing sound with exceptional authenticity. The cable is flexible, durable, and resistant to interference, approaching theoretical perfection in signal transmission.
Patent-Design Appearance with Exquisite Craftsmanship
Protected under patent number 202530634155.X, the JM6PRO II features a visible window that merges minimalist aesthetics with functional transparency. The shell is crafted from aluminum alloy through five-axis CNC curved engraving, followed by a 9-grade MHOS hardness anodized coating surface treatment. The CMP mirror polishing process delivers a premium shimmering iridescent glow with a silky-smooth texture, while providing excellent scratch and wear resistance. Every detail, from the precision craft work to the reinforced strain relief, is designed for long-term reliability.
Plug-and-Play with Wide Device Compatibility
The JM6PRO II requires no drivers or external power. Simply connect the Type-C plug to any compatible device—smartphones, computers, or tablets—and plug your 3.5mm earphones, headphones, or audio system into the other end. It supports gaming, music playback, live streaming, phone calls, microphone input, and recording functions. The adapter has been verified to work with a wide range of Type-C devices, ensuring
Compact, Portable, and Distinctively Designed
Measuring 110mm ± 10mm in length and weighing only 7.6g ± 1g, the JM6PRO II is exceptionally lightweight and portable. Its compact form factor allows for lossless high-fidelity listening anytime, anywhere. The adapter is presented in a refined silver finish, combining sophisticated aesthetics with uncompromising acoustic performance. The packaging is equipped with a matching card slot and dust-proof liner paper, ensuring premium protection during storage and transport.
