The RS2i continued Grado’s tradition of craftsmanship and acoustic excellence, with updates that made it an even more versatile and appealing headphone.

"i" Series Enhancements: The RS2i featured a thicker cable and slightly redesigned mahogany housings, improving both sound performance and build quality.
Mahogany Construction: The precision-machined wooden housings enhanced resonance control, contributing to the RS2i’s natural and warm sound signature.

Legacy: As part of the Reference Series, the RS2i maintained its position as a premium model, appealing to audiophiles and collectors alike.

The RS2i emphasized Grado’s commitment to blending traditional craftsmanship with modern engineering.

Materials: Mahogany housings, handcrafted and finished to enhance both acoustic performance and aesthetics.
Headband: Leather-covered metal band, providing flexibility and moderate comfort for extended listening sessions.
Cable: Thicker fixed Y-cable with UHPLC copper wiring, designed for durability and optimal signal transmission.

The lightweight construction and natural materials gave the RS2i a classic and elegant look, though some users found the minimal padding on the headband less comfortable during long sessions.

The RS2i delivered a rich and natural sound signature, characterized by its warmth, detail, and smoothness.

Bass: Controlled and deep, providing a strong foundation without overpowering the mids or treble.
Mids: Forward and lush, with excellent clarity and a natural tonality that brought vocals and acoustic instruments to life.
Treble: Smooth and extended, offering detail and sparkle without harshness.
Soundstage: Spacious and immersive, with precise imaging and separation that excelled in genres like classical, jazz, and acoustic music.

The RS2i’s warm and inviting sound made it a versatile performer, equally suitable for critical listening and casual enjoyment.

Like other Grado models, the RS2i attracted modding enthusiasts looking to enhance its comfort or tailor its sound to their preferences.

Common Mods:
- Replacing ear pads with G-Cush or Nyczaj Earpads to improve comfort and expand the soundstage.
- Upgrading the headband for additional padding and support.
- Re-cabling for modern connectors or balanced setups, though this required careful handling to preserve the wooden housings.
