The first Lambda series was introduced in 1979. 2016 ushers in a newly designed and entry-level for the advanced Lambda series Earspeaker, the Stax SR-L300! The SR-L300 features rich, deep bass response, delicate high-frequency and soothing mid-range in a balanced manner.
Top-Quality Sound Element:
- Tough fixed electrodes machined through stainless photo etching has 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.
Click-Type Arc Assembly:
- The arc assembly of the SR-L500 is equipped with stepless slider mechanism for head-pad height adjustment.
New Low-Capacitance OFC Wide Cable:
- OFC cable has been employed for the core wires and the whole cable uses special wide parallel structure to lower the capacitance between each wire strand.
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."
