If you want replacement earpads made specifically for Bose on-ear models in the OE2, OE2i, SoundTrue OE and SoundLink OE family, choose Krone Kalpasmos Professional Bose; if you need a general-purpose pair of protein-leather earpad cushions for everyday headphone refresh, choose ZGHUNVRE 2pcs.
• Krone Kalpasmos Professional Bose — biggest strength: Model-specific fit for the Bose on-ear (OE) series, with soft leather over high-density memory foam and a stated 3-year manufacturer warranty.
• Krone Kalpasmos Professional Bose — biggest trade-off: It is made for Bose OE-style headphones, so it is not a universal pad and won't suit unrelated brands.
• ZGHUNVRE 2pcs — biggest strength: Japanese-imported protein leather over memory foam, tool-free snap-on installation, and a design aimed at boosting passive noise isolation.
• ZGHUNVRE 2pcs — biggest trade-off: It's a general replacement pad rather than a Bose-specific part, so Bose owners won't get the explicit OE-series fit guarantee. Its warranty is also shorter at 90 days versus 3 years.
• Who each pick is for: Krone Kalpasmos for anyone restoring a Bose OE2/OE2i/SoundTrue OE/SoundLink OE headphone; ZGHUNVRE for a broad comfort-and-isolation refresh on daily-use headphones.
This is a purpose-built replacement pad. Krone Kalpasmos designed it around the Bose on-ear family, and the compatibility list is specific: OE2, OE2i, SoundTrue OE and SoundLink OE. If your headphone sits in that group and the original cushions have flattened, cracked or started flaking, this is the drop-in answer. The construction is soft leather wrapped around a high-density memory foam core, and the leather is described as anti-scratch and anti-aging, which matters because the pad surface is what takes the daily wear.
The part I find most useful on paper is the claim that the pads are tuned not to change ANC or sound. That's the whole reason people hesitate to replace OE pads at all — you don't want a fresh cushion that quietly changes the tuning you liked. Krone Kalpasmos says its engineers tested the pads across multiple Bose models specifically to preserve the headphone's existing sound and noise-cancelling behaviour. I can't verify that tuning myself from a spec sheet, but the stated intent is exactly the right one for this kind of part.
Installation is described as a few-minutes job with a supplied tool, and there's a left/right detail worth remembering: the right side has the USB port, so orientation matters. Buy this if you own a Bose OE-series headphone and want a model-matched pad with a long 3-year manufacturer warranty behind it. Skip it if your headphones aren't in that Bose family — you'd be paying for compatibility you can't use.
ZGHUNVRE takes the opposite approach: one pair of cushions meant to work across general daily-use headphones. The headline materials are Japanese-imported protein leather and memory foam, and the pitch is comfort — a smooth, skin-friendly surface for long listening sessions whether you're working from home, gaming or commuting. It's the kind of pad you buy when the originals have gone shiny, hard or uncomfortable and you just want the headphone to feel good again.
The second selling point is passive noise isolation. ZGHUNVRE describes these as thicker and snug-fitting than worn-out pads, which is a fair argument: a collapsed cushion leaks sound and lets more of the room in, so a fresh, fuller pad genuinely does tighten the seal. That's passive isolation, not active noise cancelling — worth being clear about if you're coming from a Bose background and expecting ANC.
Side-by-Side: Which Should You Choose?
• Best for Bose OE2/OE2i/SoundTrue OE/SoundLink OE owners → Krone Kalpasmos Professional Bose. The compatibility list is explicit; the ZGHUNVRE pad makes no such model-specific claim.
• Best for preserving original tuning → Krone Kalpasmos Professional Bose. Its pads are pitched as not altering ANC or sound; ZGHUNVRE's pitch is comfort and isolation instead.
• Best for passive noise isolation on generic headphones → ZGHUNVRE 2pcs. Thicker, snug-fit cushions are the stated mechanism.
• Best for the easiest install → ZGHUNVRE 2pcs. No tools, snap-on in seconds; the Krone pad uses a supplied tool and a more careful alignment process.
• Best for long-term warranty cover → Krone Kalpasmos Professional Bose. 3-year manufacturer warranty against 90 days.
• Best for daily comfort on non-Bose headphones → ZGHUNVRE 2pcs. Japanese-imported protein leather and memory foam aimed at extended sessions.
• Best for a Bose-specific material match → Krone Kalpasmos Professional Bose. Soft leather over high-density memory foam, black-on-black, anti-scratch and anti-aging.
• Best for a straightforward two-pad refresh → ZGHUNVRE 2pcs. Two pads in the pack, general-purpose fit.
In my opinion the decision is really about your headphone, not the pad. If you own a Bose OE2, OE2i, SoundTrue OE or SoundLink OE, I'd buy the Krone Kalpasmos Professional Bose — the model-specific fit and the promise of unchanged ANC and sound are exactly what you want from a part whose whole job is to disappear into your existing headphone, and the 3-year warranty backs it up. If your headphones aren't in that Bose family, the ZGHUNVRE 2pcs is the more sensible pick: tool-free, comfort-led, and built to tighten the seal. Check the current price on Amazon before you commit either way.
FAQ
It's designed for the Bose on-ear series — OE2, OE2i, SoundTrue OE and SoundLink OE. If your model isn't in that on-ear group, it's not the right pad for you.
ZGHUNVRE markets these as general replacement cushions rather than a Bose-specific part, so there's no confirmed OE-series fit. Bose owners are better served by the Krone Kalpasmos pad.
That's the main worry, and it's why the Krone pad is pitched as not altering ANC or sound. The ZGHUNVRE pad instead aims to improve passive isolation with a thicker, snugger cushion.
On paper the Krone Kalpasmos pad carries a 3-year manufacturer warranty versus 90 days for ZGHUNVRE, so for a Bose headphone it's the more durable commitment. For non-Bose daily headphones, the ZGHUNVRE pair is the simpler, lower-commitment refresh.
