If you want fresh, softer-than-stock cushions for your Beats Solo 2 or Solo 3 with a memory-foam core and a pre-attached adhesive that makes installation nearly foolproof, choose Krone Kalpasmos Earpad Replacement; if you need replacement pads for a pair of Sennheiser HD465 or HD485 headphones, choose Akkiv Replacement earpads Compatible.
• Krone Kalpasmos — biggest strength: Purpose-built for Beats Solo 2 and Solo 3 on-ear headphones, with protein leather, a high-density memory foam core, tuning cotton, and 3M 9448A double-coated tissue tape pre-attached to the back.
• Krone Kalpasmos — biggest trade-off: It only fits Beats Solo 2 and Solo 3, so if you own any other headphone it simply isn't an option; you also need to be comfortable lining up the dowel holes yourself.
• Akkiv — biggest strength: A straightforward protein-leather and memory-foam refresh for Sennheiser HD465/HD485 headphones, with a stated 90-day warranty and 24-hour customer service.
• Akkiv — biggest trade-off: It's built for a much narrower set of older Sennheiser models, and the listing gives fewer installation specifics than the Krone pad does.
• Who each is for: Krone Kalpasmos for Beats Solo 2/3 owners who want a softer, breathable cushion and an easy stick-on install; Akkiv for HD465/HD485 owners who just want their aging pads replaced with something soft and durable.
The Krone Kalpasmos pad is a focused product. It fits Beats Solo 3 wired and wireless and Beats Solo 2 on-ear wireless headphones — and that's it. No Studio, no other brands. If that's your headphone, this is exactly the kind of replacement you want; if it isn't, stop reading and move on.
What it brings to the table is a materials upgrade over the stock cushions. The surface is a professional-grade protein leather, and the description calls it softer and more breathable than the originals, with crack-resistant durability for long-term wear. Underneath sits a high-density memory foam core that the brand says wraps your ears closely and fits your head shape, which is the part that actually matters for isolation — a tighter wrap means less surrounding noise leaking in and more of each beat coming through. There's also thin tuning cotton to keep dirt out of the driver, which the brand frames as keeping the sound purer. Take the "enhanced sound" language as a design intent rather than a lab measurement: the real-world effect of a fresh, well-sealed pad versus a collapsed old one is usually a fuller low end and less leakage.
Installation is where this pad earns its keep. The dowel holes are cut to match, so the pad sits without a gap, and there's a pre-attached 3M 9448A double-coated tissue tape on the back. You peel, align, press, and you're done — no glue bottle, no guesswork about how much adhesive to use. In my opinion that single detail makes it the friendlier of the two for a first-time earpad swap.
Who should buy it: Beats Solo 2/3 owners whose pads are flaking, flattened, or uncomfortable after long sessions, and anyone who wants a white finish to match their headset. Who should skip it: anyone with a different headphone brand, and anyone who wants a pad that arrives with a long written warranty — this one advertises a lifetime guarantee from the manufacturer, but the listing itself only states compatibility and materials, so read the brand's support terms if that matters to you. The brand also suggests swapping ear cushions every 7–8 months for hygiene, which is a reasonable cadence for daily on-ear use.
Akkiv's pad is the mirror image: a narrow fit for a different headphone. It's compatible with Sennheiser HD465 and HD485 headphones, in black. Those are older wired models, and if you're still using a pair, the original pads are almost certainly the weak point by now — compressed foam, cracked coating, maybe a flaky surface. This is the part that brings them back.
The construction is what you'd expect from a decent aftermarket pad: high-density memory foam plus soft protein leather. Akkiv describes the material as softer and more resilient than what it replaces, fitting the face better and reducing pressure so long sessions don't turn into a headache. The brand also says the foam and leather are chosen specifically because they resist deforming over time — which is the real failure mode of cheap pads. A pad that keeps its shape keeps its seal, and a pad that keeps its seal keeps your bass and your isolation. That's the honest reason to care about foam density, and it's the strongest argument for this set.
Installation is described simply as a few steps to refresh the look and sound of the headphones. Fair enough — but note that Akkiv doesn't spell out the mounting method the way Krone does with its dowel holes and pre-applied tape. If you've replaced pads on this style of Sennheiser before, you'll be fine. If it's your first time, expect to look up how the originals come off before you start.
The other thing Akkiv puts forward is support: 24-hour customer service, and a stated policy of a full refund if there's a problem with the product, backed by a 90-day warranty. For a low-cost wear item that's a meaningful safety net, and it's more explicitly spelled out than what the Krone listing offers.
Side-by-Side: Which Should You Choose?
• Best for Beats Solo 2 or Solo 3 → Krone Kalpasmos Earpad Replacement. It's the only one of the two built for those headphones.
• Best for Sennheiser HD465/HD485 → Akkiv Replacement earpads Compatible. Same logic in reverse.
• Easiest installation → Krone Kalpasmos. Pre-attached 3M 9448A tape and matched dowel holes mean a peel-and-press job.
• Most explicit warranty terms → Akkiv. A stated 90-day warranty plus a full-refund policy and 24-hour service.
• Best for a white colorway → Krone Kalpasmos. Akkiv is black only.
• Best for long-session comfort claims → a tie, on paper. Both lean on memory foam and protein leather; Krone adds tuning cotton and a breathability claim, Akkiv emphasizes pressure relief and shape retention.
• Best for noise isolation by design → Krone Kalpasmos. The close-wrap memory foam core is described specifically as isolating surrounding noise.
• Best for older, harder-to-source headphones → Akkiv. HD465/HD485 pads are a smaller aftermarket niche, so a dedicated option matters more.
If I owned Beats Solo 2 or Solo 3 headphones, I'd buy the Krone Kalpasmos pad. The pre-attached 3M tape and matched dowel holes remove the most common way an earpad swap goes wrong, and the protein leather plus memory foam core is a sensible upgrade over worn stock cushions. If I owned Sennheiser HD465 or HD485 headphones, I'd buy the Akkiv pad — it's the one made for that headphone, and the stated 90-day warranty and refund policy give me a clear fallback. In my opinion the decision isn't close; it's decided entirely by which headphone is sitting on your desk.
FAQ
The Krone pad is the easier of the two, because the adhesive is already attached and the dowel holes are cut to align without a gap. The Akkiv pad is described as a few simple steps, but the listing doesn't detail the mounting method, so check how your originals are attached first.

Krone Kalpasmos suggests changing ear cushions every 7–8 months for personal hygiene. That's a reasonable guideline for daily use — and for either brand, the tell-tale signs are flaking coating, flattened foam, or a looser seal that lets outside noise in.
