The Final Audio Design SONOROUS II headphones employs a driver unit integrated with the front plate, which results in resonance being suppressed and clear sound quality. BAM technology mechanism optimises the air movement inside the housing and controls unwanted vibrations for balanced, natural sound that reduces unwanted sibilant high-frequency sounds. To achieve a high level of precision with the hard ABS housing, simulations were carried out until the appropriate level of fluidity with respect to the moulding material was achieved. The rough textured finish suppresses unnecessary vibrations. To achieve a superior fit Final have used synthetic leather earpads, which has an equal amount of flexibility both horizontally and vertically as real leather and have chosen a sponge with just the right amount of flexibility letting the Final Audio Design SONOROUS II achieve clear sound with highest levels of wearing comfort and isolation.
