Our special BAM mechanism has evolved earphone body design into a simpler, slimmer structure. And sonically, heaven IV achieves the truest possible expression of live concert hall sound. 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.
