Patented Constriction & Throttling Structure: Reduces Harsh Noise
When sound waves travel through the nozzle, changes in diameter and boundary reflections generate extra high-frequency standing wave resonance. This causes sharp high-frequency peaks, resulting in a harsh and piercing sound. Leveraging a patented constriction and throttling structure paired with a precisely tuned stepped nozzle design, this feature utilizes wave reflection and interference principles to actively eliminate abnormal resonance, smooth out high-frequency sibilance, and produce a natural, seamless treble output.
Aerospace-Grade PEK Material
The sound nozzle is precision molded from high-performance PEK (Polyetherketone) engineering plastic in a single piece. Combining high rigidity with superior internal polymer damping, multiple rounds of testing prove that PEK suppresses parasitic resonance in the shell and nozzle induced by sound pressure far better than standard materials like PC, nylon, or metal. This significantly reduces sound coloration and harmonic distortion caused by structural vibration.
Dual Acoustic Optimization: Structure + Material
Through the combined optimization of structural design and material science, this design eliminates high-frequency harshness and chaotic wave scattering. Furthermore, it fully preserves the subtle dynamic shifts and rich sonic layering of your music, delivering a rich, smooth acoustic profile across the entire frequency spectrum.
Lightweight & Comfortable: Effortless Long-Term Wear
From a wearing standpoint, PEK's low density reduces the downward pull and pressure from the housing and nozzle. Its high rigidity enables a thin-walled, compact structure that frees up space inside the ear canal, minimizing ear fatigue and pressure pain. The material offers excellent dimensional stability—resisting deformation under sweat or temperature changes to maintain a secure, sealed fit over long periods. Its low thermal conductivity provides a warm, soft-touch feel without the cold shock of metal. Additionally, high polymer internal damping prevents structural vibrations from transferring to the ear canal, mitigating listening fatigue. The seamless, one-piece molded construction features a smooth, skin-friendly surface that resists sweat and sebum, making it easy to clean and perfect for extended listening sessions.
