• High performance: To achieve more detailed performance, we have used a new dual-moving coil + five balanced armature architecture on the ST7. Employing a coaxial dual-moving coil, with the moving coil unit responsible for mid-bass and bass, and the five balanced armature units working together to handle high and mid-high frequencies. The excellent connection between the two allows us to capture richer and more nuanced details, and achieve a comprehensive improvement in high-quality detail resolution, delivering a richer and more complete sound performance
• Coaxial dual-moving coil unit design: The ST7 employs a 10mm +6mm coaxial dual-moving coil design. The advantage lies in the 10mm LCP low-frequency diaphragm, which can provide a deeper low-frequency response, enabling the audio to perform exceptionally in the low-frequency range
• Stunning Hi-Fi sound quality: The ST7 employs a high-precision three-way crossover design that meticulously calculates the playback frequencies of each driver and rationally allocates the low, mid, and high frequency ranges. This ensures a balanced and harmonious sound performance
• 2-Pin detachable design: ST7 comes standard with fever grade four strands silver plated wire, with a delicate, full and round sound. Effectively improving sound fullness while enhancing full frequency resolution, resulting in delicate and clear sound quality performance. Interchangeable design, to meet the needs of different scenarios and bring diverse experiences
• Comfortable and ergonomic design: The cavity design of the earphones, through calculating a large amount of ear print data, makes the ST7 more in line with the shape of the ear when worn, allowing you  fully enjoy zero distance contact between your ears, and allowing you to focus on music in any scene
