・【1DD+5BA Hybrid Driver Combination】KZ earphones ZS12 Pro 2 combine a 10mm full-range super linear dynamic driver with five custom balanced armature drivers to achieve optimal acoustic ratios. The dynamic and balanced armature drivers in these wired earphones each handle different frequency bands, effectively improving sound separation and clearly reproducing vocals and instrument sounds. ・【10mm Ultra-Low Frequency DD: An Engine Redefining Bass Potential】KZ-ZS12 Pro 2 in-ear monitors feature a 10mm ultra-low frequency dynamic driver. The 10mm size achieves an optimal “inertia and agility balance” for low-frequency reproduction. A high-purity iron core and radial magnetic flux array increase the magnetic flux density to 9,500 Gauss, improving the conversion efficiency from electrical signal to vibration by 35% compared to previous models. This covers a wide band from 20Hz ultra-low frequencies to 1kHz mid-low frequencies, reproducing the impact of a bass drum’s “boom” and the expansiveness of sub-bass’s “growl” with “clearity without muddiness” and “vibration that resonates in your bones.” ・【5BA Handling Mid-High and Ultra-High Frequencies: Savoring the Details of Music】ZS12 Pro 2 wired earphones feature two 31736 ultra-high frequency balanced armatures and one 30019 mid-high frequency unit on each side of the DD. From the sparkling overtones of a violin to the subtle breaths of a female vocalist, every nuance is reproduced vividly, providing a truly immersive listening experience. This multi-driver configuration achieves seamless separation and detailed reproduction across the entire frequency band. High frequencies shine brightly, and vocals deliver a natural and realistic sound quality. ・【Latest Built-in Electronic Crossover Board】The electronic crossover board equipped in KZ-ZS12 Pro 2 canal-type earphones consists of a composite system of “Digital Signal Processing (DSP) × Analog Circuit Optimization” to precisely control the “division of roles” between the dynamic driver (1DD) and balanced armature drivers (5BA). This is fundamentally different from conventional passive crossovers (signal splitting using passive components such as resistors and capacitors). These wired earphones achieve “frequency splitting at the signal input stage,” directly supplying the optimal signal tailored to each driver’s characteristics, realizing a “zero-distortion sound balance.” ・【Reference-Class HI-FI Sound Quality】KZ engineers have achieved perfectly balanced performance across three frequency bands through meticulous tuning and acoustic optimization. The 1DD+5BA multi-driver configuration requires not simply “increasing the number” of drivers, but “collaborative work to maximize the strengths of each driver.” The electronic crossover board plays the role of a “conductor” controlling this “collaboration,” connecting the “power” of the DD and the “delicacy” of the BA with a **synergistic effect of “1+1>2”**. As a result, KZ-ZS12 Pro 2 Chinese earphones balance “the impact of bass,” “the thickness of mid-range,” and “the transparency of high-range,” allowing them to deliver “the true appeal of sound” for all genres of music. ・【Precision for Gaming: Ideal for FPS Titles】The “key to victory” in FPS titles lies in instantaneous decision-making and accurate positional awareness. ZS12 Pro 2 gaming earphones wired enhance “spatial awareness,” “instantaneous response,” and “dynamic range” of game sounds to the extreme through a trinity system of “1DD+5BA hybrid driver,” “pro electronic crossover,” and “high-precision sound field control,” providing players with “information superiority through sound.” ZS12 Pro 2 is not simply “gaming earphones,” but a “tool to maximize the extraction of ‘information’ from the game through sound.” ・【Comfortable Fit & High-Purity Silver-Plated Upgrade Cable】The shell of the monitor earphones is designed to fit the natural curves of the ear based on KZ’s years of accumulated ear data modeling and ergonomic research. Combined with an over-ear cable design, it achieves stable and comfortable wearability even during long listening sessions. The included cable, made of high-purity silver-plated copper, exhibits excellent conductivity, minimizing signal loss while enabling fast and accurate signal transmission. A parallel dual-wire structure further enhances stability and interference resistance, and antioxidant properties extend cable life.

【Voltage Compatibility】 When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction.

【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary.

【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device's requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product.

【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer.
