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

MOONDROP U-2 High-Fidelity In-Ear Headphones: The dome and cone base are made of highly rigid, high-impedance, and highly compressible paper pulp, a material often in high-class speakers. By combining a "edge-cone base-dome" diaphragm structure, similar to that of full-range speaker units, with a flexible edge, it achieves a full-frequency response range far exceeding that of conventional in-ear headphones, and delivers balanced sound from low to high frequencies, with rich detail and a natural tone. The U-2 features a large 14.8mm dynamic driver that combines comfort and high performance, with a lightweight structure supporting a powerful magnetic circuit composed of N52 neodymium magnets and a CCAW voice coil. Its highly energy-efficient design and mature tuning deliver low distortion, deep and expansive bass, fast response, and treble boasting rich detail and natural extension. The U-2's design has been optimized using advanced manufacturing techniques. In particular, the use of brass tubing provides a rich resonance effect to the tone, and the viscous damping of air is utilized to optimize the effect on the bass, resulting in a unique sound quality. As a result, it achieves a clear and powerful sound while maintaining deep bass even without a sponge cover. The U-2 features a twisted, silver-plated cable, ensuring reliable transmission of audio signals. Equipped with a 3.5mm 3-pole stereo plug, it is compatible with standard audio devices. Performance testing utilizes the B&K 5128, which mimics the structure of the actual ear canal and auricle. An experienced tuning team repeatedly performs subjective listening and adjustments, resulting in a sincere and appealing sound quality.
