SMB-01L Special Edition

[layerslider_vc id=”26″]

The PHONON SMB-01L Special Edition

Professional Monitoring Headphones

An innovative headphone that reproduces large monitor studio sound

■ The PHONON masterpiece ■

Taking the international award-winning SMB-01L to even higher heights!

The frame that mounts the free edge driver is made of stainless steel to improve any breaking power and reduces the vibration of the driver unit itself, resulting in a more focused sound image.

The signal path has been optimised by using PHONON’s original 4-core + shielded cables for both left and right.
The ground is completely separated on the left and right sides to reduce common impedance interference between the left and the right.

An XLR 4-core connector model is also available as an option.

High sound quality has been achieved through further tuning, such as adjusting the reflection inside the headphones and applying frame ground control.
