"i" Series Enhancements: The SR325i featured a thicker cable, redesigned aluminum housings, and improved driver tuning to reduce resonance and enhance clarity.

Legacy: As the flagship of the Prestige Series, the SR325i remained a standout model, eventually succeeded by the SR325e in 2014.
The SR325i set itself apart from other Prestige models with its premium materials and unique aesthetic.
Materials: Precision-machined aluminum housings, providing enhanced rigidity and resonance control compared to plastic models in the lineup.
Headband: Leatherette-covered metal band, offering flexibility and a comfortable fit for most users.
Cable: Thicker fixed Y-cable with UHPLC copper wiring, designed for durability and optimal signal transmission.
The aluminum housings added weight to the SR325i, which some listeners appreciated for its premium feel but others found less comfortable during extended listening sessions.
The SR325i delivered a highly detailed and precise sound signature, making it a favorite for critical listening and analytical audiophiles.
Bass: Tight and well-controlled, providing a solid foundation without overshadowing other frequencies.

Common Mods:
Replacing ear pads with G-Cush or Nyczaj Earpads to improve comfort and soundstage.
Upgrading the headband for additional padding, especially for extended sessions.
Re-cabling for modern connectors or balanced audio setups, though this required careful handling due to the premium construction.
