Grado SR325x

The short version

What to know.

The Grado SR325x is an open-back, on-ear headphone hand-built in Brooklyn — $295 at launch and now discontinued. Three measurement rigs agree on its shape: a narrow 2 kHz spike, a 3–8 kHz region several dB below the Sennheiser HD 600, a peak around 9–10 kHz, and a little more mid-bass than the HD 600 over a deepest octave that rolls off. Reviewers broadly agree the treble is tamer than the old SR325e's, the bass tight and fuller than before, the imaging good, and that — being open-backed — it isolates almost nothing. Nearly everything else splits. Most hear a balanced, natural, 'tonally uncoloured' voicing; a sizeable minority hears a coloured, forward Grado with a 'massive' 2 kHz resonance, and a smaller one hears a darker headphone that lost the Grado bite. The stage is 'spacious' to most reviewers and 'intimate' or 'very small' to others. Comfort is the biggest complaint: about two-thirds of the weighted evidence finds the thin F pads painful within an hour or two, especially with glasses. Build divides almost evenly between reviewers' 'impressively robust' and owners' reports of dead drivers, cable failures and loose parts. Value is widely praised, but a minority argues a cheaper Grado — or the SR325x's own pads on an SR80x — gets you most of the sound.

About this product

The 2021, fourth-generation 'X' revision of Grado's metal-cupped SR325 — brushed-aluminium cups, a leather headband, the 44 mm 'X' driver, an 8-conductor cable and flat 'F-cush' pads. Not the older SR325e/SR325i (brighter, with bowl-shaped L-cush pads), and not the 2026 SR325 in Grado's Classic series, which replaced it with a new 'X2' driver and headband. The SR325x is discontinued; remaining stock and used units are what's left.

Grado Labs has hand-built headphones in Brooklyn since 1953, and the SR325 has long been the metal-bodied top of its Prestige series — the one with brushed-aluminium cups and, on this generation, a real leather headband. The SR325x was its 2021 fourth-generation update: a new 44 mm driver, a thicker braided cable and flat 'F-cush' foam pads, wrapped in the same retro, radio-operator design Grado has barely changed in three decades. In 2026 it gave way to a new SR325 in Grado's Classic series.

It was the Grado reviewers reached for when they wanted to say the house sound had grown up: fuller bass, less treble glare, still fast and forward. Owners and critics pushed back on nearly every other front — the thin pads, the fixed cable, the build, and, for some Grado loyalists, whether the new voicing had lost the very bite they bought a Grado for.

A good fit for

  • Rock, metal, jazz and vocal music where a forward, energetic midrange and quick transients are the point
  • Listeners who found older Grados too bright but want the house sound's immediacy
  • Quiet-room desk listening straight from a phone, laptop or small dongle
  • Tinkerers happy to swap pads, bend the headband or mod the cable
  • Buyers who can find one used or as remaining stock well under its old $295 price

Think twice if

  • You need all-day comfort or wear glasses — the stock on-ear pads are the most common complaint
  • You want a big, out-of-head soundstage without changing pads
  • You loved the SR325e's bright bite — some loyalists find the X darker and less lively
  • You're sensitive to a 2 kHz vocal spike
  • You want a detachable cable or worry about QC — owners report cable and driver failures
  • You need isolation or listen around other people

The reviewer consensus

Agreement &

8 / 12topics divide opinion
1 Strong agreement3 Mostly agree8 Divided opinions

Common ground6

  • The 4th-gen driver and flat pads tamed the old SR325e's treble glare — crisp and sparkly, rarely sibilant, to most ears.
  • Tight, punchy mid-bass with more weight than any earlier SR325, over a sub-bass that still rolls off.
  • Good imaging and separation for the price — instruments are easy to place.

Points of contention7

  • Tonality: balanced and natural (58%) vs still a coloured, forward Grado built on a 2 kHz spike (29%) vs too dark, with the Grado bite gone (13%).
  • Mids: present and articulate vs a 'massive 2khz resonance' that turns shouty.
  • Detail and dynamics: clean, zippy and insightful vs less resolving and less lively than the SR325e it replaced.

Sources split three ways over the same curve. Most — including the measuring reviewer who called it 'less bright, more neutral' — hear the X as the balanced, natural Grado. Others hear it as still unmistakably coloured and forward, built around a 2 kHz spike. A smaller group of Grado loyalists and one harsh critic hear the opposite problem: darker and duller than the old SR325e, with the house bite gone.

Measured

Three rigs (oratory1990's GRAS, kr0mka's 711 clone with KB501X pinnae, Auriculares Argentina), each against an HD 600 on the same rig: the 2.1 kHz peak sits at about the HD 600's own 2 kHz level; 3–5 kHz is 4.4–5.8 dB and 5–8 kHz 2–5 dB below the HD 600; a narrow 9.3–9.7 kHz peak is 8–10 dB above it; 40–200 Hz runs 1–3.5 dB above it. On InnerFidelity's rig the older SR325e measured ~4 dB hotter than its HD 600 at 2–3 kHz.

vs. listeners — The 'too dark' and 'still shouty' camps are describing different bands of the same curve: the 3–8 kHz region really is darker than the old Grado's (and the HD 600's), while the narrow 2 kHz spike Resolve calls 'massive' is still there.

Where it splits
Balanced and natural — the Grado sound grown up, less bright and more neutral than before.58%

“The overall tonal balance now tilts less bright, more neutral, darker even in some respects, while maintaining Grado's DNA on the upper mids.”

Marvey, Super Best Audio Friends
Still a coloured, forward Grado — mid-centric, energetic, far from reference.29%

“It’s definitely a coloured headphone and by no means ‘reference’”

Matty Graham, Headfonia
Too dark and veiled — the X lost the crisp Grado bite the SR325e had.13%

“the midrange is simultaneously warm and veiled, not unlike an under-driven HD600.”

What to keep in mind 6

  1. This is a read of where the reviews land as of September 2026. The SR325x has been discontinued and replaced by a new SR325 in Grado's Classic series, which is a different headphone.

  2. Many reviews are from its 2021–2023 prime; long-term owners report durability problems that short review loans don't show.
