How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a breathable, airflow-focused pad for classic Sony MDR studio headphones, choose BRAINWAVZ Perforated Replacement Earpads; if you need a straightforward leatherette repair pad for Sennheiser PXC350, HD380 and PC350-family headsets, choose GEEKRIA Leatherette Replacement Ear.
• BRAINWAVZ Perforated — biggest strength: a fully perforated protein PU leather surface over memory foam, built specifically around the Sony MDR-7506, V6 and CD900ST, with airflow and clarity as the design goal.
• BRAINWAVZ Perforated — biggest trade-off: it is a small-oval, on-ear pad. If your headphones are not an on-ear oval mount, the fit may not work even though the mounting flap is generous.
• GEEKRIA Leatherette — biggest strength: a sealed faux-leather memory foam pad matched to a long list of Sennheiser models, including PXC350, HD380, HD380 PRO, PC350, PC350 SE, PXE350, HME95 and HMEC250.
• GEEKRIA Leatherette — biggest trade-off: the leatherette surface is not perforated, so it seals more than it breathes — great for isolation, warmer over long sessions.
• Who each pick is for: BRAINWAVZ for Sony MDR owners chasing airflow and a lighter, breathable feel. GEEKRIA for Sennheiser headset owners who just want worn pads replaced with a like-for-like leatherette set.
The BRAINWAVZ Perforated pad is a niche product done deliberately. It is a small-oval replacement cushion sized around 3.94 x 0.79 x 2.95 inches, and it exists because the Sony MDR-7506, MDR-V6 and MDR-CD900ST have been in studios and home setups for decades — and their stock pads eventually flatten, crack or shed. This set is designed as the fix, or as an upgrade if you never loved the stock feel.
What makes it different from a generic replacement is the surface. The whole pad is covered in tiny perforations, and the material is protein PU leather wrapped over high-grade memory foam. Perforations let air move through the pad instead of trapping heat against your ear. In practice, that is what turns a long editing session or a mixing marathon from "I need to take these off for five minutes" into something you can keep wearing. The memory foam does the other half of the job: it spreads pressure instead of pressing a hard ring against your skull.
BRAINWAVZ also leans on fit as a sound feature. A pad that seats properly around the ear seals predictably, which supports isolation and keeps the low end from leaking away. The perforated top and the sealed mounting edge work together here — breathability where your ear sits, grip where the pad meets the cup.
Who should skip it? Anyone with a large, round over-ear headphone whose pads mount completely differently. Also skip it if you specifically want maximum passive isolation in a loud room — perforations trade a little sealing for airflow by design, and a solid leatherette pad is the more logical tool for that job.
GEEKRIA Leatherette Replacement Ear: Who It's For
The GEEKRIA Leatherette pad plays a different role: it is a repair part. Its job is to take a Sennheiser headset with collapsed, flaking or uncomfortable cushions and return it to a wearable state without overthinking the equation. It is made from memory foam with a faux leatherette cover, black, and it measures roughly 4.33 x 3.35 x 0.87 inches — a noticeably larger footprint than the BRAINWAVZ pad, which tracks with the bigger Sennheiser cups it serves.
The compatibility list is the headline: PXC350, HD380, HD380 PRO, PC350, PC350 SE, PXE350, HME95 and HMEC250. That spread covers noise-cancelling travel headphones, wired monitoring cans and communication headsets — a genuinely useful range for one pad. GEEKRIA also notes it will fit other brands and models if the dimensions line up, so measuring your cups before ordering is the smart move.
The leatherette surface is the key design trade. It is smooth, sealed and easy to wipe down, and it blocks more outside noise than a perforated surface would. For a PC350 headset used for calls, or an HD380 used in a noisy room, that sealing is a feature, not a flaw. The cost is warmth: closed leatherette holds heat against your ear, and after a couple of hours you will feel it. That is the honest trade-off, and it is the exact opposite of what the BRAINWAVZ pad is built for.
Two practical details matter. First, this is a two-piece set — you get two earpads, and the headphones themselves are not included. Second, GEEKRIA backs the pad with a one-year manufacturer warranty and a stated SureFit policy: if you mismatched your headphone type or the pads did not fit, you contact them. That is a meaningful safety net for a part that is easy to order wrong.
Side-by-Side: Which Should You Choose?
• Sony MDR-7506, V6 or CD900ST owner → BRAINWAVZ Perforated. It is designed for those exact models.
• Sennheiser PXC350, HD380/PRO, PC350/SE, PXE350, HME95 or HMEC250 owner → GEEKRIA Leatherette. The compatibility list matches your headphone.
• Best for breathability and long listening sessions → BRAINWAVZ Perforated. The full perforated surface is the entire design premise.
• Best for passive noise blocking → GEEKRIA Leatherette. Sealed faux leather isolates more than a perforated cover.
• Best for a headset that just needs new life → GEEKRIA Leatherette. Straightforward repair part, two pads, one-year manufacturer warranty.
• Best for reviving a classic studio monitor → BRAINWAVZ Perforated. Memory foam plus a large rear mounting flap made for small-oval mounts.
• Best for a wider over-ear cup → GEEKRIA Leatherette. Its 4.33 x 3.35 inch footprint suits larger Sennheiser cups.
• If your mount is unusual → measure first, then pick; both brands list compatible models rather than claiming universal fit.
In my opinion, the deciding factor here is your headphone, not the pad. If you own a Sony MDR-7506, V6 or CD900ST, I would buy the BRAINWAVZ Perforated set — the perforated surface and memory foam are aimed squarely at the discomfort that makes people retire these classics, and the compatibility is explicit rather than hopeful. If you own any Sennheiser on the GEEKRIA list, I would buy the GEEKRIA Leatherette pad: it is a clean, sealed repair part with a warranty behind it. Neither is the "better" pad in the abstract. Match the pad to the cup and you will be happy with either.
BRAINWAVZ Perforated. Its compatibility list names the Sony MDR-7506, MDR-V6 and MDR-CD900ST directly. The GEEKRIA pad is cut for Sennheiser models on its own list, not the Sony MDR line.
Not better — different. Perforations let air move through the pad, so they stay cooler over long listening sessions. Sealed leatherette blocks more outside noise but traps more heat. Pick based on whether you prioritize breathability or isolation.
Yes for the GEEKRIA set, which is listed as a 2-count of replacement earpads with the headphones themselves not included. The BRAINWAVZ set is likewise sold as a pair of replacement cushions for your existing headphones.
Check the compatibility list first, then the dimensions. BRAINWAVZ measures about 3.94 x 0.79 x 2.95 inches and GEEKRIA about 4.33 x 3.35 x 0.87 inches. If your model is not named, compare those figures against your current pads before ordering, and check the current price on Amazon once you have settled on the right size.
