Key Features：

1. Dual Magnetic Circuit & Dual Cavity Design – Surging Power System – The dynamic driver adds an independent back sound cavity that quickly accumulates and compresses air to increase power, enhancing sound explosiveness and detail performance. Induction intensity of the double magnetic flux exceeds 1T, delivering better electro-acoustic conversion rate and transient response – outstanding sound quality with surging power.

2. 10mm High Polymer PET Diaphragm – Fine & Accurate Restoration – Good toughness, rigidity, and fatigue resistance with rapid response speed. Rich sound details with clear and delicate texture – achieves fine and accurate restoration of details and phases for a truly engaging listening experience.

3. High-Density PC Cavity – Exclusive Customized Appearance – Cavity is fully enclosed with high-density PC material molded under high temperature. Effectively suppresses diffuse reflection of sound inside the cavity. Skin-friendly, simple, and stylish – showcasing a sense of beauty and technology. KBEAR exclusive molding appearance patent.

4. Expert Tuning – 20 Years of Acoustic Engineering Experience – Carefully controlled sound quality by a KBEAR acoustic engineer with 20 years of experience in the field. Constantly surpassing itself to deliver a refined, high-performance sound signature.

5. 4-Core 4N Pure Copper Cable – Enhanced Permeability – High-purity 4N pure copper wire enhances permeability for more textured low frequencies, better vocals, and higher overall sound quality. Stable, lossless signal transmission for pure audio enjoyment.

6. Improved 2-Pin Plug with Limit Slot Protection – Based on analysis of various detachable cable interfaces and in-depth study of user experiences. Limit slot added to effectively protect the pin from breaking and extend product life. Standard 0.78mm 2-Pin design supports future cable upgrades.

7. Ergonomic Fit – Comfortable for Long-Term Listening – Optimizations based on ergonomic design, curvature of front cavity, and inclination angle of conductor. Comfortable to wear with good sound insulation – suitable for extended listening sessions without fatigue.

8. Aluminum Alloy Sound Guide Nozzle – Effectively avoids sound resonance for cleaner, more accurate sound reproduction. Enhanced clarity and detail across all frequencies.

9. Lightweight Design – Only 4.0g Per Earpiece – Ultra-light body with UV varnish covering for a smooth, elegant finish that shines like new. Reduces ear fatigue for all-day comfort.

10. Balanced Sound Trends – Versatile for Multiple Genres – Benefits from dual magnetic circuit and dual cavity advantages. Good energy efficiency and transient response – easily driven by mobile phones. Low-frequency elasticity and transients are fast and powerful; vocals are warm, mellow, and dense; strong resolution with rich details. Overall sound is balanced with both quality and musicality – suitable for vocal, rock, ACG, and omnivorous music styles.

11. Easy-to-Drive Performance – Compatible with smartphones and portable players without requiring an external amplifier. A perfect entry point into high-fidelity audio.
