2. Features a 13mm high-dynamic moving coil driver, delivering vinyl-grade sound quality with rich bass, an expansive soundstage, and highly restored vivid audio.
3. Supports ANC active noise cancellation, which accurately cancels out ambient noise by generating anti-phase sound waves, creating a quiet private space.
4. Equipped with ENC call noise reduction algorithm and dual high-definition microphones, intelligently separating human voice from background noise and reducing wind noise for crystal-clear calls.
