Modding Potential

The SR125 expanded on the success of earlier Prestige Series models by introducing more refined driver tuning and improved build quality. It became a favorite among audiophiles for its engaging sound and excellent value in the mid-tier headphone market.

A True Mid-Tier Model: Positioned between the SR80 and SR225, the SR125 offered a noticeable jump in sound quality without the price tag of higher-end models.
First to Use UHPLC Cables: The SR125 was among the first Prestige models to feature ultra-high purity copper (UHPLC) cabling, enhancing signal transmission and clarity.
Longevity: The SR125 has remained a staple in Grado’s lineup, evolving through the SR125i, SR125e, and SR125x iterations.

The SR125 retains the classic Grado design language, combining retro aesthetics with lightweight construction for a comfortable listening experience.

Materials: Plastic housings with a matte black finish, paired with metal gimbals for durability.
Headband: Leatherette-covered metal band with minimal padding, typical of Grado’s Prestige Series.
Cable: Fixed Y-cable featuring UHPLC copper, designed for improved signal transmission and durability.

While the SR125’s build quality is solid, some users find the lack of premium materials and minimal padding less comfortable for extended sessions.

The SR125 is celebrated for its detailed and lively sound signature, offering a significant step up in clarity and resolution compared to the SR80.

Bass: Tight and controlled, with slightly better depth and definition than the SR80.
Mids: Forward and articulate, bringing vocals and acoustic instruments to life with exceptional clarity.
Treble: Crisp and extended, offering remarkable detail without becoming overly sharp.
Soundstage: Intimate yet precise, with excellent imaging and separation.

The SR125 excels in genres that demand detail and precision, such as classical, jazz, and acoustic music, while still being engaging for rock and pop.

The SR125, like other Grado models, is highly customizable and popular among modding enthusiasts. Its modular design makes it easy to tweak for improved comfort and sound.

Common Mods:
- Swapping ear pads for G-Cush or Nyczaj Earpads to enhance comfort and expand the soundstage.
- Upgrading the headband to a padded alternative for extended listening comfort.
- Re-cabling for modern connectivity and increased flexibility.
- Adding acoustic dampening materials to adjust treble response and add warmth.

The SR125 has earned its place as a mid-tier favorite in the Prestige Series lineup, praised for its engaging sound and excellent value for money.

Community Reception:
- Widely regarded as one of the best headphones in its price range, the SR125 is often recommended for those seeking a balance of performance and affordability.
- While some listeners prefer the SR225 for its added refinement, many find the SR125 hits the sweet spot for critical listening without a steep investment.
Rarity:
- Early versions of the SR125 are still relatively common, but unmodified units in pristine condition are increasingly sought after by collectors.
