PHONON / SMB01L

PHONON/SMB-01L are monitor headphones made with audio professionals in mind.

■New flagship model
-Enjoy the natural ultra-low frequency produced by the newly adopted 50mm driver and the acoustic space produced by PHONON's original technology. The diaphragm operates with good response and low energy loss due to the free edge structure, achieving a frequency response that fully covers the high-resolution band and a wide dynamic range. The tuning technology that PHONON has cultivated over the years enables playback sound that is closer to the real sound, and by repeatedly playing various reference discs, we achieve the best acoustic balance regardless of genre.

■Evolved 50mm driver unit
・Foster Electric MT050A is a high-end 50mm driver unit that achieves low distortion and a wide playback band. Equipped with a powerful magnetic circuit with the highest level of magnetic flux density in the industry. In order to achieve even higher resolution, we have adopted a ``Biodyna diaphragm'' made from biocellulose material, and the edges that support the diaphragm are ``free edges'', achieving frequency characteristics that fully cover the high-resolution band and a wide dynamic range.

■Beyond the flat
- What is required in the world of recording engineers is a monitoring environment that can capture sound flatly, and the SMB-01L numerically achieves a high level of flat sound. However, this is just a ""flat frequency response,"" and determining whether a sound is good or bad involves other complex factors, and PHONON has developed products that pursue these complex factors from multiple angles. PHONON's goal is to achieve musical joy by achieving a numerically flat sound at a high level. PHONON continues to pursue the best sound possible.
