Do Replacement Cushions Really Change Grado Headphone Sound?

Quick answer

Yes, replacement cushions can change what you hear on Grado headphones, but the change comes from fit, seal, and driver distance, not from a hidden tuning trick. The right pad for your model keeps the sound close to what Grado intended; the wrong pad can shift comfort and tonal balance in ways you may not like. Match the cushion to your headphone first, then judge the sound.

Grado cushions are not cosmetic. They set how far the driver sits from your ear, how much pressure you feel, and how much outside noise reaches you. Change any of those and your perception of the sound changes too.

That has spawned a few myths: that any pad will "upgrade" the sound, that thicker is always better, or that a swap can fix a headphone you do not like. Here is a clear verdict on each, using only what Grado publishes about its own cushions.

Myth: Any replacement cushion will improve the sound

Verdict: false. A cushion is a fit part, not a tuning upgrade. Grado builds each headphone around a specific pad: the S-Cushions are standard on the SR60, SR80, and SR125, while the F-Cushions are standard on the SR225, SR325, and Hemp. Those pairings exist because the pad is part of the design, not an accessory you can freely swap for a "better" one.

If you move to a pad your model was not designed around, you are changing the distance and seal between driver and ear. That can make the sound feel different, but different is not automatically better. The honest test is whether the headphone still sounds like the headphone you bought.

• Start by checking which cushion is standard for your exact model before buying anything.
• Treat a pad swap as a fit change first and a sound change second.

Myth: Pads do not affect sound at all, so buy the cheapest

Verdict: also false. Pads sit between the driver and your ear, so they influence what reaches your ear. Grado's own lineup uses different cushions across different models, which is a strong signal that the pad is part of the intended presentation rather than an afterthought.

Price alone is a poor guide. The I-Cushions cost less than the S-Cushions and F-Cushions, but they fit only the iGrado and eGrado. Buying them for an SR60 or RS1 because they are cheaper gets you a pad that was not made for your headphone. Compatibility, not price, is the first filter.

• Check the fit list on the product page before comparing prices.
• A cheaper pad that does not fit your model is not a bargain.

Myth: You need new pads to change the sound on Grado headphones

Verdict: usually false, and often backwards. Worn or flattened cushions change the fit, and fit changes what you hear. Replacing tired pads with the correct new ones restores the intended fit rather than altering the design. That is maintenance, not tuning.

If your current pads are compressed, dirty, or no longer sit correctly, a fresh set of the same model is the most predictable move. You get the sound the headphone was designed to deliver, plus better comfort. Only after that baseline is restored does it make sense to experiment.

• Replace like for like first when pads are worn.
• Judge any sound difference only after the new pads have settled into normal use.

Myth: Thicker cushions always mean more bass

Verdict: unsupported. Grado does not publish bass claims tied to cushion thickness, and the catalog does not list thickness as a tuning specification. What the catalog does show is that each cushion has a defined fit list and a defined set of models it ships with.

The practical takeaway is simple: choose the pad your model was built around, and let comfort and fit guide you within that. If you want a different tonal character, that is a headphone choice, not a cushion choice. Do not buy a pad expecting a bass boost the manufacturer never promised.

• Ignore thickness claims that are not backed by the maker's own fit list.
• Use the standard pad for your model as your reference point.

Verdicts on common Grado cushion claims

• Any pad improves the sound: Grado assigns specific cushions to specific models, such as S-Cushions on the SR60, SR80, and SR125 and F-Cushions on the SR225, SR325, and Hemp. Verdict: false. Match the pad to the model.
• Pads make no difference at all: Cushions sit between driver and ear, and Grado uses different cushions across its lineup rather than one universal pad. Verdict: false. Fit and seal matter, even if the change is not a tuning upgrade.
• New pads are the way to change your sound: Worn pads change fit, so replacing them with the correct model restores the intended fit instead of altering the design. Verdict: mostly false. Replace like for like first.
• Thicker means more bass: Grado's catalog lists fit and model compatibility, not thickness-based bass claims. Verdict: unsupported. Choose by compatibility, not by thickness.

Grado cushions and cases: what the catalog actually says

• Grado Headphone Replacement S-Cushions: Consumer replaceable genuine Grado ear cushions, standard equipment on the SR60, SR80, and SR125, and fitting all Prestige, Reference, Statement, Professional, and Limited Edition headphones. If you own one of those models, this is the like-for-like replacement that keeps the fit and sound you already know.
• Grado Headphone Replacement F-Cushions: Genuine Grado ear cushions, standard equipment on the SR225, SR325, and Hemp, and also fitting all Prestige, Reference, Statement, Professional, and Limited Edition headphones. Owners of those models should start here rather than experimenting with a different pad shape.
• Grado Headphone Replacement I-Cushions: Consumer replaceable genuine Grado ear cushions that fit the iGrado and eGrado only. A clear example of why fit lists matter: these are the right pads for two models and the wrong pads for everything else.
• Large Hard-Shell Case for Grado Headphones: Hard-shell zipper case with embossed Grado logo, fitting PS1000e, PS2000e, GS1000e, GS2000e, GS3000e, and RS1e, and noted as the correct case for any headphone with G-cushions. Storing headphones properly keeps cushions from being crushed, which protects the fit you just restored.

Replacement cushions change what you hear mainly through fit, seal, and driver distance, not through hidden tuning. Check which pad your Grado model was built around, replace worn pads with the same type, and only then decide whether you want a different headphone rather than a different cushion.
