Sound Description

Modding Potential

The SR325 was introduced as the flagship of the Prestige Series, offering audiophiles a taste of Grado’s high-end sound at a more accessible price point than the Reference Series.

First to Use Metal Housings: The SR325 was the first Prestige model to feature aluminum housings, which contributed to reduced resonance and a more precise sound.
Longevity: Over the years, the SR325 has been updated to the SR325i, SR325e, and SR325x, each bringing subtle refinements in design and tuning.
Signature Brightness: The SR325’s treble-focused sound has been both a hallmark and a point of contention, earning it a reputation for incredible detail but also potential fatigue for treble-sensitive listeners.

The SR325’s design reflects Grado’s minimalist philosophy but with premium touches that set it apart from other Prestige models.

Materials: Machined aluminum housings with a brushed finish, offering improved durability and reduced resonance.
Headband: Leather-covered metal band with minimal padding, similar to other Prestige models.
Cable: Fixed Y-cable featuring UHPLC copper wiring for superior signal transmission and clarity.

While the aluminum housings add a sense of durability and sophistication, some listeners find the SR325 heavier than other Prestige models, which can impact long-term comfort.

The SR325 is celebrated for its exceptional clarity and detail, making it an excellent choice for critical listening. Its sound signature is brighter and more analytical than other Prestige models, delivering an engaging and precise listening experience.

Bass: Tight and fast, with excellent control but not as deep as some listeners might prefer.
Mids: Forward and highly detailed, with a natural presentation of vocals and instruments.
Treble: Extended and sparkling, providing remarkable detail and air but potentially fatiguing for treble-sensitive ears.
Soundstage: Wider and more spacious than earlier Prestige models, with excellent imaging and instrument separation.

The SR325 is particularly well-suited for genres like classical, jazz, and acoustic music, where its clarity and precision shine.

The SR325 is a popular choice among modders, thanks to its robust construction and straightforward design. However, the aluminum housings make certain modifications slightly more challenging than with plastic models.

Common Mods:
- Replacing ear pads with G-Cush or Nyczaj Earpads to expand the soundstage and enhance comfort.
- Upgrading the headband for improved long-term comfort.
- Re-cabling for modern connectors and added flexibility.
- Experimenting with acoustic dampening materials to balance the treble and enhance the bass.

Collectibility and Reception

The SR325 is widely regarded as a standout in the Prestige Series and has earned a dedicated following among audiophiles.

Community Reception:
- Praised for its clarity, detail, and engaging sound signature, the SR325 is often considered the best value for listeners seeking high-end performance without stepping into Grado’s Reference Series.
- Some listeners, however, find its bright treble to be overly intense for long listening sessions.
Rarity:
- While not as rare as vintage Grado models, early versions of the SR325, especially those in pristine condition, are increasingly sought after by collectors.

The Grado SR325 remains a hallmark of the Prestige Series, offering a premium listening experience with its detailed sound, durable build, and timeless design. Whether stock or modified, the SR325 is a favorite for those seeking an engaging and precise headphone that balances performance and affordability.
