How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want to bring a pair of worn-out Beats Mixr on-ear headphones back to life, choose Koffmon Replacement Ear Pads; if you need a complete wired USB-C listening setup for a new phone or laptop, choose TOPAUX USB Type C.
These two products sit in completely different corners of the headphone world. One is a repair part. The other is a finished pair of earbuds. That sounds like an odd matchup, but it's actually a very common crossroads: people land on both pages while trying to fix or replace their everyday audio gear, and they're not always sure which path they're on. So let me draw the line clearly.
• Koffmon Replacement Ear Pads — biggest strength: Protein leather over memory foam that forms a real seal, restoring comfort and bass on headphones you already own.
• Koffmon Replacement Ear Pads — biggest trade-off: It only works with Beats Mixr wired on-ear headphones. If that's not your model, this product does nothing for you.
• TOPAUX USB Type C — biggest strength: A complete, self-contained USB-C earbud kit — wingtips, three eartip sizes, inline mic and controls, magnetic neck-wearing design, and a zipper case.
• TOPAUX USB Type C — biggest trade-off: It's a wired USB-C connection only. No 3.5mm jack, no wireless mode, so older devices with a round headphone port are out.
• Who each pick is for: Koffmon for Mixr owners repairing existing headphones; TOPAUX for anyone who needs working earbuds today on a USB-C phone, tablet or laptop.
The Koffmon pads exist to solve one specific, annoying problem: your Beats Mixr on-ear headphones still work fine, but the cushions have flattened, peeled, or vanished. The drivers are healthy, the cable is fine, and yet the headphones are uncomfortable and the bass has gone thin. Rather than replace the whole headphone, you swap the pads.
What you get is a pair of black cushions built from protein leather wrapped around memory foam. That combination matters more than it sounds. Memory foam compresses and rebounds to your ear shape, which is what keeps pressure off the outer ear during long sessions — the "ear fatigue" problem on-ears are famous for. The denser the foam, the better the seal, and a better seal is what brings back the low end. If your Mixr bass feels weak lately, worn pads are usually the reason, not a broken driver. Fresh foam restores that coupling between driver and ear.
Installation is genuinely tool-free. The pads snap into place and Koffmon includes printed instructions, so you're looking at a few minutes of work, not a repair project. The stitching and materials are described as built for daily use, and there's a one-year warranty backing the pair. Each pad measures roughly 2.8 x 2.8 x 1.2 inches, which lines up with the on-ear footprint of the Mixr.
Buy it if: you own Beats Mixr wired on-ear headphones and want the comfort and low-end back without buying new headphones. Skip it if: you own any other headphone model, or if you're actually shopping for earbuds to plug into a phone. This is a compatibility-specific part, and the compatibility list here is exactly one model.
The TOPAUX USB Type C is the opposite kind of purchase: not a fix, but a full kit. It's a wired in-ear headphone that terminates in a USB-C plug, which is the whole point — modern phones and laptops have dropped the round jack, and this plugs straight into what you actually have.
The design details here are unusually thoughtful for a wired earbud. The wingtips are the standout: flexible fins that lock into the curve of your ear so the earpieces stay put instead of working loose every few minutes. That "anti-loose" idea shows up again in the magnets built into each earpiece, which let you clip the buds together around your neck when you pull them out — no more dangling and swinging. The white housings use a mix of composite, metal, plastic and rubber, and the earpieces are IPX4-rated for sweat and water resistance, which covers workouts, commutes in bad weather, and general abuse.
Sound is handled by a dynamic driver with a 32-ohm impedance and a 20–20,000 Hz frequency range, paired with a DAC chip in the USB-C connector and a custom acoustic platform tuned for deep bass. The in-ear fit itself does real work here: a proper seal with the right eartip isolates a meaningful amount of surrounding noise, which is why the spec sheet lists sound isolation as the noise-control approach rather than active cancellation. You get three eartip sizes (S, M, L) to find that seal, plus a zipper PU storage case.
The cable runs about 4.9 feet and is described as tangle-free, with an inline module for play/pause, track skipping, call answer/end/reject, volume, and waking your voice assistant. The compatibility list is enormous — recent iPhone models, a long run of Samsung Galaxy phones and tablets, Pixel devices, iPad, MacBook, and more. Basically, if your device has a USB-C port and supports USB-C audio, this is aimed at you.
Buy it if: you need one pair of wired earbuds that works across a USB-C phone, tablet and laptop, and you want them to stay in your ears during movement. Skip it if: you're on an older device with a 3.5mm jack, or you want wireless freedom. This is a wired product, full stop.
• Best for reviving hardware you already own → Koffmon Replacement Ear Pads. Nothing else here restores a specific headphone.
• Best for a complete, ready-to-use kit → TOPAUX USB Type C. Eartips, wingtips, case, mic and controls all come in the box.
• Best for on-ear comfort and bass restoration → Koffmon. Memory foam plus protein leather is the whole design brief.
• Best for working out and moving around → TOPAUX. IPX4 sweat resistance, secure wingtips and magnetic neck-wearing are built for it.
• Best for calls and quick controls → TOPAUX. The inline remote and mic handle calls, tracks and volume; Koffmon has no electronics at all.
• Best for a single specific headphone model → Koffmon. It's compatible with Beats Mixr wired on-ear headphones, and that's the list.
• Best for the widest device compatibility → TOPAUX. The USB-C list spans iPhone, Samsung, Pixel, iPad and MacBook.
• Best for the smallest, most targeted fix → Koffmon. If your only complaint is flat, peeling pads, this solves it directly.
In my opinion, the right pick comes down to one question: are you fixing or starting fresh? If you already own Beats Mixr headphones and the pads are the only thing wrong, I'd buy the Koffmon Replacement Ear Pads — it's the cheaper, simpler path to the comfort and bass you remember, and there's really no substitute when the fit is this specific. If you don't own a Mixr, or you're setting up a new USB-C phone or laptop and want earbuds that stay put and handle calls, I'd buy the TOPAUX USB Type C instead. It's the more versatile purchase by a wide margin, because it works across far more devices and arrives as a complete package. The only real mistake here is buying Koffmon pads for headphones they don't fit — check your model first, then commit.
FAQ
No. The listed compatibility is Beats Mixr wired on-ear headphones only. They're shaped and sized for that model specifically, so they won't snap correctly onto other on-ear or over-ear designs. Verify your model name before ordering.
They use passive sound isolation rather than active noise cancellation. The in-ear seal, helped by the three included eartip sizes, blocks a good amount of surrounding noise, and the acoustic tuning emphasizes deep bass. For a wired set, that's a solid result.
Both are affordable in their own categories, but I won't quote numbers here — check the current price on Amazon using the button on this page. On value, it depends on your situation: Koffmon is the smarter spend if you're salvaging a working headphone, while TOPAUX gives you more hardware for the money if you need earbuds anyway.
Only if your device has a USB-C port that supports audio. Older iPhones with Lightning and devices with a 3.5mm jack won't connect directly without an adapter. The compatibility list covers recent USB-C iPhones, most modern Samsung and Pixel devices, iPads and MacBooks.
