Industry-First Glass Diaphragm*
The glass diaphragm minimizes unwanted vibrations, reproducing every detail from low to high frequencies.
Experience exceptional clarity, a wide soundstage, and crisp, dynamic playback.
*For wireless earbuds.
*Images are for illustrative purposes only.
Combining a high-performance MEMS driver with excellent high-frequency reproduction and a 2-way bi-amp configuration enables precise sound control.
Independent amplifiers for each frequency band reduce distortion and deliver clear, high-resolution audio.
The synergy between the glass diaphragm and the MEMS driver reveals fine musical nuances, creating a wider, more immersive soundstage.
Newly Developed
Liquid Silicone Eartips
Made from liquid silicone, these eartips offer greater flexibility than conventional solid silicone, improving the seal for better noise isolation, reduced sound leakage, and higher sound quality.
Their umbrella-shaped, oval design minimizes pressure on the ear while providing strong noise isolation and a secure, stable fit.
World-Leading*
