The SR-L500 features rich deep bass-response, delicate high-frequency and soothing mid-range all in a balanced manner. 

Top-Quality Sound Element:
Strictly selected thin-film diaphragm as well as tough stainless fixed electrodes have also been employed for the SR-L500. Thus rich deep bass-response, delicate high-frequency and soothing mid-range have been realized in a balanced manner. 
Click-Type Arc Assembly:
The arc assembly of the SR-L500 is equipped with 10-click slider mechanism for head-pad height adjustment. Once adjusted, the slider always maintains its optimal position to make its readjustment unnecessary. This enables you to enjoy hours of pleasant listening to music with optimal wear comfort. 
New Low-Capacitance HiFC Wide Cable:
High-performance new HiFC cable has been employed for the core wires. The whole cable uses the conventional wide parallel structure to lower the capacitance between each wire strand. This further improves the "freshness of sound." 
High-Quality Artificial Leather Ear Pad:
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."
