Grado SR100 Headphones

The Grado SR100 was one of the earliest entries in Grado Labs’ Prestige Series, marking a significant moment in the company's transition from professional-grade models like the HP1000 to more accessible options for audiophiles and casual listeners alike.

Released in the early 1990s, the SR100 helped establish Grado’s reputation for delivering high-quality, open-back headphones with a unique sound signature at an affordable price.

Sound Description

Modding Potential

The SR100 is believed to be among the first models in the Prestige Series, aimed at making Grado’s signature sound more accessible to the growing market of audiophiles in the 1990s. While its exact release date and production details remain somewhat elusive, it shares many design elements with its siblings, the SR200 and SR300.

Early versions of the SR100 are thought to use drivers similar to those in the HP1000 series, albeit with less rigorous matching and tuning.
The SR100 was entirely handcrafted in Brooklyn, New York, as part of Grado’s commitment to in-house production.
This model has become increasingly rare in its original, unmodified form, as many units have been altered by enthusiasts over the years.

The SR100 features a straightforward, utilitarian design that reflects Grado’s early philosophy of simplicity and function over flash. Its lightweight construction makes it comfortable for long listening sessions, though it may not feel as premium as later models.

Materials: Plastic housings with a matte black finish and metal gimbals for durability.
Headband: A simple leatherette band with minimal padding.
Cable: A fixed Y-cable, thicker than those on modern Grado models, known for its robustness but prone to tangling.

While the build quality is solid for its time, the lack of premium materials might leave modern users underwhelmed compared to Grado’s higher-end offerings.

The SR100 is often praised for its lively and engaging sound, which aligns closely with Grado’s trademark tuning. However, its sound signature reflects its position as an early Prestige model, leaning slightly raw and less refined compared to later iterations.

Bass: Tight and punchy, though lacking the depth and impact of Grado’s modern models.
Mids: Forward and detailed, with a focus on vocals and acoustic instruments.
Treble: Crisp and energetic but can be sharp or fatiguing for treble-sensitive listeners.
Soundstage: Intimate, with good imaging but less spacious than higher-end Grado headphones.

The SR100 excels in genres like rock, acoustic, and indie, where its energetic presentation truly shines.

As with most Grado models, the SR100 has significant modding potential due to its modular design and simplicity. Many enthusiasts have modded their SR100 units to improve comfort and sound quality.

Common Mods:

Upgrading the ear pads to larger or more comfortable options, like G-Cush or Nyczaj Earpads, to enhance bass and soundstage.
Replacing the headband with a padded alternative for extended listening comfort.
Re-cabling to reduce stiffness and improve durability.
Adding acoustic dampening materials to smooth out the treble and add warmth to the mids.

Collectibility and Reception

The SR100 holds a special place in Grado’s history as one of the first steps toward the accessible Prestige Series lineup. It is sought after by collectors for its historical significance and connection to Grado’s early days.

Community Reception:

The SR100 is fondly remembered for its engaging sound and value at the time of release. However, it is often overshadowed by its more refined successors in the Prestige Series.
Audio enthusiasts appreciate the SR100’s role in shaping Grado’s design and sound philosophy, even if its technical performance is outclassed by modern models.

Rarity:

Finding an SR100 in its original condition is increasingly difficult, as many have been heavily modded. Pristine examples command a premium in the second-hand market.

The Grado SR100 remains an intriguing piece of Grado’s legacy, offering a glimpse into the brand’s early efforts to bring high-quality sound to a broader audience. Its combination of history, modding potential, and unique sound makes it a cherished addition to any Grado enthusiast’s collection.
