Description
Description
The SMB-01L was created by mastering engineer and PHONON CEO Isao Kumano with audio professionals in mind, aiming to deliver studio large monitor sound in headphones.
Enjoy natural ultra-low frequencies with the newly adopted 50mm driver and an acoustic space created by PHONON's proprietary technology. The free-edge structure provides diaphragm movement with excellent response and minimal energy loss, achieving frequency characteristics and a wide dynamic range that fully covers the high-resolution range. PHONON's accumulated tuning technology enables playback that is closer to the original sound, and by repeatedly playing various reference discs, we have achieved the best acoustic balance regardless of genre.
Main Features
Enjoy closed dynamic or semi-open sound with this single unit. Equipped with 50mm free-edge drivers with interchangeable plates. Premium sheepskin ear pads for comfort, durability, and excellent sound insulation. Detachable cable (4-wire system with independent left and right ground connections).
