• YunYiYi's biggest strength: a genuine two-step, no-tools install and a black memory foam cushion designed specifically around the iJoy Logo ISO over-ear headset.
• YunYiYi's biggest trade-off: it fits one headphone family only, and the fit is the loudest thing about it — get the model wrong and it simply will not seat properly.
• YOCOWOCO's biggest strength: thicker memory foam plus softer leather in a light blue finish, aimed at Bose QC45, QC SE and the new QuietComfort wireless over-ear models.
• YOCOWOCO's biggest trade-off: it is a Bose-shaped pad, and the upgrade is about comfort, isolation and bass rather than broad compatibility.
• Pick YunYiYi if you own the iJoy Logo ISO and just want the pads back to normal in seconds.
• Pick YOCOWOCO if you own a compatible Bose QuietComfort and want the pads to feel plusher than stock.
YunYiYi keeps this product deliberately narrow. The pad is pitched as a replacement for the iJoy Logo ISO Over Ear Bluetooth Headphones STL, and it comes as a single pair of black cushions — the headphone itself is not in the box. That narrowness is the point. Instead of a universal ring that half-fits everything, you get a cushion shaped for one headset, which is exactly what you want when the original foam has flattened out and started flaking.
The two things that stand out in the spec sheet are the install and the foam. Installation is described as a simple two-step job with no tools required, measured in seconds rather than minutes. The cushioning is memory foam, and YunYiYi ties that directly to isolation and sound: the pad conforms to the shape of your ear, blocks out more of the room, and the headphone ends up sounding better than it did with worn-out foam. There is also a durability claim worth noting — when the pads are not in use they return to their original shape, which is how memory foam is supposed to behave and how a pad avoids the permanent dent that ruins cheaper cushions.
Who should buy it? Anyone who owns the iJoy Logo ISO, likes the headphone, and is annoyed by comfort rather than sound. If your pads have gone hard, thin or shiny, this is the cheapest-feeling fix in the sense that it costs you almost no effort. Who should skip it? Anyone with a different headphone. The compatibility line names one model family, and there is no sizing chart or adapter ring here — this is not a "probably fits" purchase. It is also not for someone chasing a color change, since the only finish listed is black. If you want a visual refresh, look elsewhere in this comparison.
YOCOWOCO goes the other way: broader compatibility within one brand, and an upgrade in materials rather than a straight like-for-like swap. The pads are listed as compatible with the Bose QuietComfort 45 (QC45), QuietComfort SE (QC SE), the new QuietComfort wireless over-ear headphones, and QuietComfort wireless noise cancelling headphones. If you own one of those and your originals are tired, this is the intended audience.
The material story is the interesting part. YOCOWOCO uses high-density memory foam and pairs it with softer leather, and the company claims the combination both reduces external noise and lifts the bass. That is a plausible pairing: denser foam seals better against your head, a better seal keeps low frequencies from leaking away, and leather that is softer than the original is usually the difference between "fine for an hour" and "fine for a full shift." The pads ship in light blue, which is a real style choice rather than a neutral black, and they measure roughly 4.13 by 3.35 by 0.79 inches, so they are a compact, standard-size over-ear cushion rather than a bulky one.
Installation is described as easy and measured in a few minutes — slightly more involved than the YunYiYi two-step, but nothing that requires special tools. There is also a six-month warranty listed, which is a concrete, checkable promise rather than vague marketing language, and YOCOWOCO points buyers to its own after-sales channel for issues. Who should buy it? Bose QuietComfort owners who want the pads to feel softer, seal better and add a touch of low end. Who should skip it? Anyone who does not own a compatible Bose model — the fit is brand-specific, and no adapter is included. If you want plain black to match your headphone, the light blue finish will not be for you either.
Side-by-Side: Which Should You Choose?
• Best for a fast, zero-effort swap → YunYiYi Replacement Earpad. Two steps, no tools, seconds of work.
• Best for thicker, plusher foam → YOCOWOCO Replacement Ear Pads. High-density memory foam paired with softer leather.
• Best if you own Bose QC45, QC SE or the new QuietComfort → YOCOWOCO Replacement Ear Pads. That is the exact compatibility list.
• Best for bass and noise isolation as a stated goal → YOCOWOCO Replacement Ear Pads. The product specifically claims both.
• Best for a neutral color match → YunYiYi Replacement Earpad. Black is the only finish listed; YOCOWOCO is light blue.
• Best for a stated warranty → YOCOWOCO Replacement Ear Pads. Six months is documented in the product details; YunYiYi lists no warranty term.
• Best for keeping the same sound signature you already like → YunYiYi Replacement Earpad. Its pitch is restoring the headphone, not changing it.
For a call center setup, the practical logic runs a little differently than the marketing. The pads that come with your headset were tuned for that headset, so a like-for-like replacement like the YunYiYi keeps the mic boom position and clamping force exactly where your ears expect them. A thicker pad like the YOCOWOCO changes the distance between driver and ear slightly, which is usually a comfort win and a small tonal change. If you are shopping for a headset from scratch, the same logic applies to categories: the best on ear headphones for call center work trade isolation for lighter weight, the best open ear headphones for call center work keep you aware of your surroundings but leak sound both ways, and the best clip on earbuds for call center work are the lightest option of all — but none of those replace a worn pad on a headset you already like.
If I owned a Bose QuietComfort 45, QC SE or new QuietComfort, I would buy the YOCOWOCO Replacement Ear Pads. In my opinion the denser foam, softer leather, light blue finish and documented six-month warranty make it the more substantial purchase of the two, and the comfort gain is the thing you actually notice on a long call center shift. If I owned the iJoy Logo ISO, I would buy the YunYiYi Replacement Earpad without hesitating — it is the correct, purpose-built part for that headset and the install is genuinely trivial. Match the pad to the headphone you already own, then check the current price on Amazon before you commit.
FAQ
can you sleep with over ear headphones
You can, but the pads matter more than the headphone here. Both of these are memory foam over-ear cushions, and memory foam is the type that compresses and recovers — YunYiYi explicitly says the pads return to their original shape when not in use. Side sleeping on a headset is still uncomfortable regardless of the pad, so if sleep is the goal, a slimmer cushion is the better bet.
The cups should sit over your ears, not on them, with the headband centered on the top of your skull. Slide the yokes out until the pads seal gently against your head without pressing. Both the YunYiYi and YOCOWOCO pads rely on that seal for the isolation they claim — a loose fit wastes the memory foam entirely.
how should over ear headphones fit
Snug but not tight. The pad should compress slightly against your head all the way around, with no gap at the bottom where sound leaks out. YOCOWOCO's pads are listed at roughly 0.79 inches thick with high-density foam, so expect a firmer, fuller seal than a thin worn-out original. If you feel pressure above your ears after an hour, the headband needs adjusting, not the pads.
how to wear over ear headphones properly
Same principle, one step further: adjust the headband before you judge the pads. Put the headset on, then lengthen each side equally until the cups cover your ears completely and the cushion sits flat against your head. If you have just installed new pads — a two-step job on the YunYiYi, a few minutes on the YOCOWOCO — give the memory foam a day or two to settle into your head shape before deciding whether the fit is right.
