The subtle nuances of the music and the tones of the instruments are conveyed more clearly, providing an immersive music experience. The speakers use air pressure adjustment and a sound cavity to effectively suppress sound leakage. While being open-ear, it protects the user's privacy, creates a personal space, and allows you to enjoy immersive Hi-Fi sound as is.
