Grado SR325 Classic Series - Black

Description

Precision Metal Engineering for Acoustic Clarity

The Grado SR325 represents a landmark performance tier within the renowned Classic Series lineup, serving as an exceptional choice for listeners who demand uncompromised fidelity from their high-fidelity systems. At the core of its acoustic design is a precision-machined aluminum housing. This rigid metal structure serves a critical acoustic purpose: it aggressively minimizes internal acoustic resonances that can muddy fine details. By controlling these unwanted vibrations, the aluminum enclosures support a remarkably fast, controlled, and transparent presentation, ensuring that the listener hears nothing but the intended musical waveform.

Advanced X2 Dynamic Driver Technology

Sustaining Grado's reputation for world-class transient response and rhythmic timing, the SR325 integrates a sophisticated 44mm X2 dynamic driver platform. This system utilizes a high-grade Mylar diaphragm paired with an ultra-responsive copper voice coil and a potent rare earth magnet array. Every element is meticulously engineered to prioritize efficiency and precise driver control. The custom tuning focuses heavily on articulation and speed, resulting in tightly defined bass response, an immediate, forward midrange that captures vocal nuances, and an extended, crisp top-end that reveals the natural shimmer of instruments without causing listener fatigue.

Refined Ergonomics and Comfort

Long listening sessions require structural integrity and adaptive comfort, which the SR325 provides through its Signature Silver headband assembly. Derived from the engineering principles of higher-tier architectures, this assembly uses engraved, reinforced polymer gimbals and robust junction blocks. This design improves overall geometric alignment and provides controlled rotation while shedding unnecessary physical weight. The genuine leather headstrap features contrasting white stitching for a luxury aesthetic, while the internal steel spring band allows listeners to easily adjust the clamping pressure for a personalized fit. Combined with a flexible, woven Signature Silver cable that reduces drag, this headphone feels balanced on the head and integrates seamlessly into any stationary desktop or dedicated listening station.

The Pure Open-Back Experience

As an open-air dynamic design, the SR325 is built to deliver exceptional musicality, natural instrument separation, and an expansive soundstage. This design allows sound to radiate freely outward, eliminating the enclosed, artificial resonance typical of closed-back alternatives. To preserve this energetic and immediate presentation, the headphones come equipped with standard Grado F cushions, which seat the ear at the optimal distance from the transducer. This physical pairing ensures superb tonal balance and emotional engagement, allowing audiophiles to appreciate the full dynamic scale of their high-resolution audio libraries.

Common Questions

Why choose the Grado SR325 headphones?

The Grado SR325 is designed specifically for critical music listeners, desktop audiophiles, and hi-fi enthusiasts who want to maximize sonic detail without moving into the extreme luxury price tiers. It provides an ideal solution for those who prioritize a wide, lifelike soundstage, rapid instrument transients, and transparent vocal clarity. Its open-back architecture and machined metal housing make it perfect for dedicated listening environments where musical purity is paramount.

What is the advantage of the aluminum housing on this model?

The precision-machined aluminum housing is an engineering upgrade that controls and dampens unwanted structural resonances. By neutralizing these stray vibrations, the metal casing allows the 44mm drivers to deliver a much faster, cleaner, and more precise acoustic performance than composite or plastic alternatives.

What kind of cable does the Grado SR325 have?

This model is equipped with Grado's Signature Silver cable. It features a thick, woven, and highly flexible design that reduces overall weight and minimizes cable twisting, making it highly durable and convenient for long stationary listening sessions.

Can I change or replace the ear cushions on the SR325?

Yes. The SR325 comes standard with Grado F cushions to deliver an energetic, immediate sound profile. However, Grado cushions are designed to serve as an accessible tuning element, meaning listeners can easily swap or personalize them to adjust comfort and customize the acoustic experience.

What are the power requirements for these headphones?

With a normal impedance of 38 ohms and a sensitivity of 98 dB SPL at 1mW, the SR325 is highly efficient and can easily be driven by a variety of audio sources. While they perform beautifully with a dedicated headphone amplifier or desktop DAC setup, they can also be operated effectively by standard audio components.
