Always Included

  1. Top-quality sound element

Tough fixed electrodes machined through stainless photo etching have also been employed for the SR-L300. Thus rich deep bass response, delicate high frequency, and soothing mid-range have been realized in a balanced manner.

  1. Slide-type arc assembly

The arc assembly of the SR-L300 is equipped with a step-less slider mechanism for head pad height adjustment.

  1. New low-capacitance OFC wide cable

OFC cable has been employed for the core wires and the whole cable uses a special wide parallel structure to lower the capacitance between each wire strand.

  1. High-quality artificial leather earpad

The high-quality flexible artificial leather ear pad contributes not only to improve the wear feeling but also to enhance the "freshness of sound" and "the grace of sound."
