How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want replacement pads built specifically for the JBL Quantum ONE with a snap-in install and a long warranty, choose defean Protein Leather Earpads; if you need fresh cushions for a Studio 2, Studio 3, B0500 or B0501 headphone, choose Axuzsyx Ear Pads Replacement. These two look similar on a shelf — black protein leather, memory foam, sold as a single pair — but they are aimed at completely different headphones, and that single fact decides the purchase before anything else.
• defean's biggest strength: it is purpose-built for the JBL Quantum ONE, with a tool-free snap-in install and a 12-month warranty.
• defean's biggest trade-off: it fits that one headphone family only — it will not work on a Quantum 100, 400, 600 or 800.
• Axuzsyx's biggest strength: it covers the whole Studio 2 / Studio 3 / B0500 / B0501 family and ships with the pry bar you need to get the old pads off.
• Axuzsyx's biggest trade-off: installation is a twist-and-lock job that needs a bit of dexterity, and it is not made for JBL gaming headsets at all.
• Buy defean if you own a JBL Quantum ONE. Buy Axuzsyx if you own a Studio-series or B0500/B0501 headphone.
The defean pads exist for one job: putting a fresh cushion on a JBL Quantum ONE. The manufacturer states compatibility with the Quantum ONE over-ear ANC gaming headphone and explicitly warns that this is not for the Quantum 100, 600, 800 or 400, or any other JBL model. That narrowness is the point. Instead of a generic oval that "sort of" fits, you get a pad shaped for that specific ear cup, which matters a lot on a headset where the pads sit over angled drivers and an ANC microphone array.
The materials are straightforward: protein leather on the outside, high-density noise-cancelling foam inside, all in black. defean describes itself as a factory that specialises in ear pad acoustics, and the pitch here is comfort plus noise isolation — the foam is meant to seal against your head so less outside sound reaches your ears and less of your game audio leaks out. For a Quantum ONE owner who games late or takes calls in a shared room, that seal is the whole reason to replace worn pads rather than live with flattened ones.
Installation is the other selling point. defean says you pull the old pads, seat the new ones into the ear cups and press them in — no pry bar, no screws, no tools, and the brand claims the whole thing takes under a minute. The package is one pair of pads with the headphone not included, backed by a 12-month warranty and what defean calls free service support. So who should skip it? Anyone whose headset is not a Quantum ONE. If you own a Quantum 600 or 800, this is not your pad, and no amount of stretching will make it right.
Axuzsyx takes the opposite approach: broad coverage of one headphone family rather than deep specialisation on a single model. The pads are listed as compatible with Studio 2, Studio 3, B0500 and B0501 wireless headphones — the classic on-ear/over-ear shape that a huge number of people still use daily. If your stock cushions have cracked, gone shiny, or started flaking black flakes onto your ears, this is the direct replacement route.
The build is protein leather over memory foam, sold in black, with Axuzsyx claiming the protein skin is softer and more skin-friendly than the originals, and that the memory foam resists deforming over time. The brand also leans on noise isolation and tone: it says the high-density foam blocks distraction and enhances alto and bass tones. Read that as a design claim, not a lab result — denser foam and a tighter seal generally do push bass forward and tame outside noise, which is exactly what people notice when they swap tired pads for fresh ones.
The install is where Axuzsyx differs. These pads are held by a twist-lock system: you lever the old cushions off with the included pry bar, line up the button holes on the new pads with the buttons on the headphone, press down and rotate to lock. It is not hard, but it is fiddlier than a snap-in design, and the pry bar in the box is there for a reason. The package is one pair of cushions plus that bar, headphones not included, with a one-year warranty on parts. Skip these if you are shopping for a JBL Quantum ONE — they are simply not made for it.
• Own a JBL Quantum ONE → defean Protein Leather Earpads. It is the only one of the two designed for that headset.
• Own a Studio 2, Studio 3, B0500 or B0501 → Axuzsyx Ear Pads Replacement. The defean pads will not fit these.
• Fastest, tool-free install → defean. Press-and-seat versus pry-bar-and-twist.
• Everything you need in the box → Axuzsyx, because the pry bar ships with the pads; defean assumes no tools are needed at all.
• Longest stated warranty → defean, at 12 months, against Axuzsyx's one year on parts — close, but defean frames it as worry-free.
• Noise isolation priority → either, since both use high-density memory foam; the seal is what does the work on both headsets.
• Material feel → a tie on paper. Both are protein leather over memory foam in black; Axuzsyx explicitly markets its skin as softer than stock.
• Gaming vs. everyday listening → defean for the Quantum ONE gaming headset, Axuzsyx for the Studio/B0500 family of listening headphones.
In my opinion the choice is not really a choice at all — it is decided by the headphone on your desk. If you own a JBL Quantum ONE, I would buy the defean Protein Leather Earpads: purpose-built fit, a genuinely tool-free install, and a 12-month warranty make it the safer bet for that specific headset. If you own a Studio 2, Studio 3, B0500 or B0501, I would buy the Axuzsyx Ear Pads Replacement, because the defean pads are not compatible with your headphone and Axuzsyx gives you the pry bar you will need. Check your model number first, then check the current price on Amazon before you commit.
No. defean lists compatibility with the Quantum ONE only and specifically excludes the Quantum 100, 600, 800 and 400, plus other JBL models. Confirm your model before ordering.
No. Axuzsyx lists compatibility with Studio 2, Studio 3, B0500 and B0501 headphones. For a Quantum ONE, the defean pads are the matching option.
defean, by design — you seat the pads and press them in with no tools. Axuzsyx uses a twist-lock mount, so you pry the old cushions off with the included bar, align the button holes, press and rotate.
Match the pad to your headphone, not the other way around. Quantum ONE owner, take the defean pair. Studio 2, Studio 3, B0500 or B0501 owner, take the Axuzsyx pair. Both use protein leather over high-density memory foam, so the real difference is fit and mounting system.
