HE GuoJia 10mm Dual Dynamic Driver In-Ear Wired HiFi Headphones, 0.78pin Replaceable Cable with Four-Strand Oxygen-Free Copper Wire

Inspired by the Three Kingdoms strategist Guo Jia, observing the vast spectrum of sound waves, perceiving the subtle mysteries of pitch and rhythm, and mastering the ultimate acoustic path of balancing the virtual and the real. The shell combines a 3D-printed resin base with a precision-crafted aluminum alloy faceplate. The resin texture is warm and gentle, while the metal finish is sharp and cool. The collision of warm and cool textures is just like a strategist: calm and composed on the outside, while harboring profound vision and grand strategy within.

The acoustic architecture features dual 10mm frequency-divided dynamic driver units. The low frequency utilizes a self-developed solid wood sliced diaphragm, while the high frequency adopts a mature and stable PET diaphragm. Each diaphragm excels in its designated realm with distinct roles, perfectly mirrored like a strategic battle plan where each position is held, complementing one another seamlessly. The tuning is unique, capturing the deep, grand, and grounded character of Guo Jia. The high frequencies are smooth and refined, suppressing harsh edges to eliminate any sibilance or brightness. The mid-range vocals are forward and prominent—rich, solid, warm, and moving—with a crystal-clear separation between vocals and instruments that accurately restores the distinct warmth and body of human voices. Leveraging the inherent acoustic properties of the solid wood diaphragm, the low frequency delivers deep, full extension with rich, three-dimensional impact and sharply defined layering, unfolding a lush and lingering musical ambiance.

With a 1kHz sound pressure level reaching 114dB, it boasts outstanding sensitivity. Standard smartphones can drive it directly to unlock its full sound quality without relying on high-end portable players. Much like a master strategist planning from behind the scenes, it effortlessly controls the entire musical landscape without requiring external aid. The sound background is deep, composed, and unpretentious, versatile across various musical genres. Relying on the rich, warm acoustic character of the wood diaphragm, it composes a legendary soundscape hidden within the depths of the music.
