Modding Potential

The SR125i built upon the legacy of the original SR125 by incorporating design and performance enhancements that made it even more appealing to audiophiles.

"i" Series Improvements: As with other models in the “i” series, the SR125i featured a thicker cable and larger housing for improved durability and resonance control.
Mid-Tier Performer: The SR125i struck a balance between price and performance, offering a noticeable step up from the SR80i while staying below the cost of the SR225i.
Legacy: The SR125i continued the lineage of its predecessor as a mid-tier favorite in the Prestige Series, eventually succeeded by the SR125e in 2014.

Materials: Lightweight plastic housings with a matte finish, designed for portability and durability.
Headband: Leatherette-covered metal band with light padding, providing a flexible yet secure fit.
