If you want replacement ear pads tailored specifically to Sony wireless TV headphones for commuting, choose Krone Kalpasmos Ear Pads; if you need a universal 70mm soft-foam pad that can revive almost any worn-out headphone in your drawer, choose Pssopp Universal Soft Foam.
• Krone Kalpasmos Ear Pads — biggest strength: model-specific fit for Sony WH-RF400R, MDR-RF995RK, MDR-RF895RK, MDR-RF995R and TMR RF 400, with memory foam and protein leather built for daily wear.
• Krone Kalpasmos Ear Pads — biggest trade-off: it only makes sense if you actually own one of those Sony models; there is no universal sizing here.
• Pssopp Universal Soft Foam — biggest strength: a 70mm universal pad (70 x 70 x 20mm) that fits a wide range of headphones and claims to reduce outside noise through its soft foam build.
• Pssopp Universal Soft Foam — biggest trade-off: "universal" means it may not match the exact mounting or cup geometry of your specific headphone, so fit is a gamble.
• Who each pick is for: Krone Kalpasmos is for Sony owners who want a drop-in, no-tools replacement; Pssopp is for anyone with an odd or older headphone who just wants a cheap way to bring it back to life.
The Krone Kalpasmos Ear Pads are a purpose-built replacement, not a generic one. The company lists compatibility with Sony WH-RF400R, MDR-RF995RK, MDR-RF895RK, MDR-RF995R and TMR RF 400 headphones — a tight list, and that is the whole point. If your model is on it, you are getting a cushion shaped for your specific cup rather than a circle you have to hope fits.
The build is the other selling point. The pads use memory foam wrapped in high-density protein leather (faux leather), which the brand describes as crack-resistant and durable. At 14.2 g for the pair, they are light, and the black finish keeps things low-key. Krone Kalpasmos also mentions that the pads are hand-crafted, so sizing can vary by a few millimetres — worth knowing if you are fussy about an exact match.
Installation is tool-free and adhesive-free, and the brand says it takes only minutes with the included tutorial. Krone Kalpasmos recommends swapping ear cushions every 7 to 8 months for hygiene and comfort, and states the pads can last 180 days or more.
Who should buy it: Sony WH-RF400R, MDR-RF995RK, MDR-RF895RK, MDR-RF995R or TMR RF 400 owners whose original pads have flattened, cracked or gone shiny. It is a straightforward refresh.
Who should skip it: anyone whose headphone is not on that compatibility list. There is no universal sizing here, so if you own a different brand, this is the wrong product for you.
Pssopp takes the opposite approach: one pad, many headphones. These are 70mm round cushions (roughly 70 x 70 x 20mm, about 0.79 inch thick) made from protein leather over soft foam. The listing describes the material as durable and flexible, with a soft foam layer that helps block outside noise for a more immersive listen.
The pitch is restoration, not precision. Pssopp frames these pads as a way to "breathe new life" into old headphones — pull off the worn ones, push on the new ones, done. No tools, no adhesive, seconds rather than minutes. Each pack contains one pair, left and right, in black, weighing 14 g total.
The honest caveat is the word "universal." A 70mm pad will physically fit a lot of headphones, but fit is not the same as a match. If your headphone uses a specific mounting ring, an oval cup, or a non-standard attachment, a generic round pad may sit loose, shift, or change the seal. Pssopp covers this with a 90-day manufacturer warranty.
Who should buy it: someone with an older or off-brand headphone, a spare pair, or a model where original pads are no longer easy to find. It is also a reasonable pick if you just want a soft foam pad for long listening sessions and are not precious about a factory-perfect fit.
Who should skip it: anyone who owns one of the Sony models Krone Kalpasmos covers. If a made-for-your-model option exists, taking the universal route is a needless risk.
Side-by-Side: Which Should You Choose?
• Best for an odd or older headphone → Pssopp Universal Soft Foam. The 70mm universal sizing is the whole reason to pick it.
• Best for noise blocking → Pssopp Universal Soft Foam. Pssopp explicitly builds its pitch around soft foam reducing outside noise; Krone Kalpasmos focuses on comfort and durability instead.
• Best for long-session comfort → Krone Kalpasmos Ear Pads. Memory foam plus protein leather is the more comfort-tuned combination of the two.
• Best for tool-free, low-fuss installation → tie. Both are adhesive-free and tool-free; Krone Kalpasmos says minutes, Pssopp says seconds.
• Best for longevity claims → Krone Kalpasmos Ear Pads. The brand states 180 days or more of use and recommends a 7–8 month replacement cycle.
• Best for commute use → Krone Kalpasmos Ear Pads, assuming you own a compatible Sony model — a correct fit keeps the seal intact, which matters more on a train or bus than in a quiet room.
• Best for reviving a headphone you were about to throw out → Pssopp Universal Soft Foam. It is the cheaper gamble when nothing model-specific exists.
For commuting, I would buy the Krone Kalpasmos Ear Pads — but only if my headphone is one of the Sony models it lists. In my opinion, a made-for-your-model pad beats a universal one almost every time, because the seal is what actually does the noise-blocking work on a busy train. If you own a Sony WH-RF400R, MDR-RF995RK, MDR-RF895RK, MDR-RF995R or TMR RF 400, this is the pad I recommend. If your headphone is anything else, skip straight to the Pssopp Universal Soft Foam, accept the fit compromise, and enjoy the fact that a tired old pair gets a second life.
FAQ
They are 70mm round pads, so they fit a wide range — but "universal" is not a guarantee. Headphones with oval cups or specific mounting rings may not seat properly, so check your cup size before ordering.
Pssopp specifically advertises its soft foam as reducing outside noise. Krone Kalpasmos does not make a noise-blocking claim — its focus is comfort and durability. In both cases, a proper seal against your head matters more than the pad alone.
Krone Kalpasmos recommends changing ear cushions every 7 to 8 months for hygiene and comfort, and states its pads can last 180 days or more. If your current pads are cracked, flaking or flat, replacement is overdue regardless of brand.
