----------------------------------------------------------------------
【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.

【1DD+5BA Hybrid Driver Combination】The KZ ZS12 Pro 2 earphones combine a 10mm full-range super-linear dynamic driver with five custom balanced armature drivers to achieve an optimal acoustic ratio. The dynamic and balanced armature drivers, found in wired earphones, each handle different frequency bands, effectively improving sound separation and reproducing vocals and instrument sounds clearly.
[10mm Ultra-Low Frequency Dynamic Driver: An Engine Redefining the Possibilities of Bass] The KZ-ZS12 Pro 2 in-ear monitors feature a 10mm ultra-low frequency dynamic driver. The 10mm diameter achieves the optimal balance of inertia and agility for bass reproduction. High-purity iron core and radial magnetic flux arrangement increase magnetic flux density to 9,500 gauss, improving the conversion efficiency from electrical signals to vibrations by 35% compared to previous models. This covers a wide frequency range from ultra-low frequencies of 20Hz to mid-low frequencies of 1kHz, reproducing the impactful "thud" of a bass drum and the expansive "whoosh" of a sub-bass with "unmistakable clarity" and "a vibration that penetrates to the bone."
[5BA drivers handling mid-high and ultra-high frequencies: Savoring the details of music] The ZS12 Pro 2 wired earphones feature two 31736 ultra-high frequency balanced armature drivers and one 30019 mid-high frequency unit on each side. From the sparkling harmonics of a violin to the subtle breath of a female vocalist, every nuance is reproduced with vivid clarity, providing a truly immersive listening experience. This multi-driver configuration achieves seamless separation and detail reproduction across the entire frequency range. High frequencies shine clearly, and vocals are rendered with natural and realistic sound quality.
【Latest Built-in Electronic Crossover Board】The electronic crossover board installed in the KZ-ZS12 Pro 2 in-ear headphones is composed of a composite system of "digital signal processing (DSP) x analog circuit optimization," precisely controlling the "division of labor" between the dynamic driver (1DD) and balanced armature drivers (5BA). Fundamentally different from conventional passive crossovers (signal division using passive components such as resistors and capacitors), it achieves "frequency division at the signal input stage" in wired headphones, directly supplying the optimal signal tailored to the characteristics of each driver, thereby achieving "distortion-free sound balance."
[Reference-Grade 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 just "increasing the number," but "coordinated work to maximize the strengths of each driver." The electronic crossover board plays the role of the "conductor" controlling this "coordination," combining the "power" of the DD and the "delicacy" of the BA in a **"1+1>2" synergistic effect**. As a result, the KZ-ZS12 Pro 2 Chinese earphones possess a well-balanced combination of "powerful bass," "rich midrange," and "clear treble," delivering the "true sonic charm" of all genres of music.
[Precise Game-Ready Performance: Ideal for FPS Titles] In FPS titles, the key to victory lies in instantaneous decision-making and precise positioning. The ZS12 Pro 2 wired gaming earphones, with their three-pronged system of "1DD+5BA hybrid driver," "professional electronic crossover," and "high-precision sound field control," maximize the spatial awareness, instantaneous response, and dynamic range of game sounds, providing players with a sound-based information advantage. The ZS12 Pro 2 is not just a "gaming earphone," but a "tool that maximizes the information extracted from games through sound."
【Comfortable Fit & High-Purity Silver-Plated Upgraded Cable】The monitor earphone shells are designed to fit the natural curves of the ear, based on KZ's years of accumulated ear data modeling and ergonomic research. Combined with the over-ear cable design, it provides a stable and comfortable fit even during extended listening sessions. The included cable, made of high-purity silver-plated copper, exhibits excellent conductivity, enabling high-speed and accurate signal transmission while minimizing signal loss. The parallel dual-wire structure further improves stability and interference resistance, and its anti-oxidation properties extend the cable's lifespan.
