• Krone Kalpasmos — biggest strength: Wide Bose compatibility (QC35, QC35 II, QC25, QC15, QC2, AE2, AE2i, AE2w, SoundLink) with a breathable cloth-and-leather build and memory foam tuned for noise canceling.
• Krone Kalpasmos — biggest trade-off: It's deliberately model-specific, so it only makes sense if you own one of the listed Bose headphones. The blue/grey pattern look is also a style choice, not a neutral one.
• SUNGOOYUE — biggest strength: A simple, no-fuss black cushion using sponge plus protein skin leather, positioned as a general replacement for worn headset pads across home, office, commute and travel.
• SUNGOOYUE — biggest trade-off: The spec sheet keeps compatibility vague ("for headset"), so you have to confirm your model fits before buying. No Bose-specific model list is given.
• Pick Krone Kalpasmos if you own a listed Bose model and want a precise, breathable, color-forward replacement.
• Pick SUNGOOYUE if you want an affordable-feeling, general-purpose black refresh and you're comfortable checking fit yourself.
The Krone Kalpasmos Earpads are the more specialized of the two. This is a replacement pad engineered around one family of headphones — the Bose QuietComfort line and its siblings — rather than a generic "fits most" cushion. The materials tell the story: the pad is pressed from cloth and leather, wireless stitched around the whole circumference, which the maker says improves airtightness and helps preserve the sound the headphones were tuned to deliver. If you've ever swapped pads on a QC35 and noticed the bass go thin, that airtightness point is exactly the thing you care about.
The memory foam is the second half of the pitch. It's a denser foam chosen to support noise canceling rather than just sit there, and there's a dust mat included to keep the inside of the cup clean and filter debris. In practice, that means the pad is doing two jobs: comfort on the ear and protecting the driver area underneath. Installation is presented as a few-minute job with the necessary tools and replacement parts in the box, so you're not hunting for a spudger.
Who should buy it? Anyone who owns a Bose QC35, QC35 II, QC25, QC2, QC15, AE2, AE2i, AE2w or a SoundLink headphone and wants a pad that matches the original geometry and keeps the seal intact. The blue with grey pattern leather is a genuine style statement — it replaces the usual boring black — so it suits someone who wants their headphones to look different, not identical to stock.
Who should skip it? If you don't own one of those Bose models, this isn't your pad — the fit is specific, not universal. And if you want a plain black, invisible replacement that nobody notices, the bold color scheme works against you.
The SUNGOOYUE Headphone Ear Cushions take the opposite approach: broad, simple, and neutral. The build is sponge plus protein skin leather — a combination chosen for a balance between softness and structure, so the pad holds a consistent shape during regular use instead of collapsing after a few weeks. Protein leather is the softer, smoother-feeling option here, and the black finish is designed to blend into common headset styles rather than stand out.
The positioning is squarely about restoration. The sheet frames these as replacements for worn or flattened ear pads — the kind of pad that has gone shiny, lost its bounce, and started pressing on your ears during long sessions. The intended settings are everyday ones: home office, studying, commuting, travel. Nothing exotic, just the places where you wear headphones for hours and notice discomfort creeping in.
Compatibility is where you need to pay attention. The spec describes these as compatible "for headset" without naming specific models, so the honest read is that this is a general-purpose cushion, not a model-matched one. Before buying, measure your existing pads or check the cup dimensions against the listing. It also carries a 90-day manufacturer warranty, which is worth noting for a consumable part like this.
Who should buy it? Someone with a headset whose pads are tired, who wants a clean black look, a soft protein-leather surface, and doesn't need a pad tied to a specific premium model line. It's also a sensible pick if you simply want a spare set to rotate in.
Who should skip it? If you own a Bose QC-series headphone and want a guaranteed drop-in fit with a documented model list, the vaguer compatibility here is a real risk. And if you specifically want a breathable fabric surface rather than leather-feel, this isn't that.
Side-by-Side: Which Should You Choose?
• Best for breathability → Krone Kalpasmos Earpads. The cloth-and-leather pressed construction is aimed at airflow, which matters in warm rooms or long summer sessions.
• Best for preserving noise canceling → Krone Kalpasmos Earpads. The stitched seal and memory foam are both described around airtightness and NC support.
• Best for a neutral, invisible look → SUNGOOYUE Headphone Ear Cushions. Plain black that matches common headset styles.
• Best for soft, leather-feel contact → SUNGOOYUE Headphone Ear Cushions. Protein skin leather is the softer surface of the two.
• Best for general headset refresh → SUNGOOYUE Headphone Ear Cushions. It's framed as a broad replacement for worn pads, not a model-specific part.
• Best for a spare set / rotation → SUNGOOYUE Headphone Ear Cushions. Buying two and swapping is easier when the pad isn't tied to one premium model.
• Best for someone who wants their headphones to look different → Krone Kalpasmos Earpads. The blue and grey pattern is the whole point of that design.
If I owned a Bose QC35, QC25 or any of the listed models, I'd buy the Krone Kalpasmos Earpads — no hesitation. The explicit compatibility list, the sealed cloth-and-leather construction and the memory foam aimed at noise canceling all add up to a pad that's designed for that specific headphone rather than hoping to fit. The breathable surface is the detail I'd appreciate most day to day.
I'd go with the SUNGOOYUE Headphone Ear Cushions only if I didn't own a listed Bose model, or if I wanted a cheap-feeling spare set in plain black with a soft leather surface. It's the more flexible, less precise option — and for a generic headset, that's fine.
Check the current price on Amazon for both before deciding; the gap matters more for a consumable part than for almost anything else.
FAQ
The Krone Kalpasmos pads are the breathable option — they're built from pressed cloth and leather with airflow in mind. SUNGOOYUE uses sponge plus protein skin leather, which is softer and smoother but not described as breathable.
A proper seal helps noise canceling work as intended. Krone Kalpasmos specifically designs its stitched, airtight construction around supporting NC. A loose or poorly seated generic pad can weaken that effect.
Krone Kalpasmos includes the necessary tools and replacement parts and describes installation as a few-minute job. SUNGOOYUE's instructions are simply to remove the old pads and fit the new ones — no tools mentioned.
SUNGOOYUE states a 90-day manufacturer warranty. Krone Kalpasmos doesn't list a warranty term in the data provided, so factor that in if coverage matters to you.
