Heaven IV
Our special BAM (Balancing Air Movement) Mechanism, which optimizes air movement inside the housing, has pushed the evolution of earphone body design to the next level with a simpler structure and slimmer body. The result is a balanced, natural sound that reduces unwanted sibilant high-frequency sounds. The heaven Ⅳ delivers deep spatial expression and a true “live sound” atmosphere.
