How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want to refresh and upgrade a pair of large over-ear headphones you already own, choose BRAINWAVZ XL Hybrid Memory; if you need a complete wireless, noise-cancelling headphone for commuting, travel and calls, choose Kinglucky UPGRADE Noise Cancelling. These two products share almost nothing except the words "memory foam" — one is a replacement part, the other is a finished headphone. So the real question isn't which is "better." It's which job you're actually trying to get done.
• BRAINWAVZ XL Hybrid Memory — biggest strength: a hybrid velour-and-perforated-PU-leather build over high-grade memory foam, sized XL and round, with a large rear mounting flap that lets it fit a long list of big over-ear models.
• BRAINWAVZ XL Hybrid Memory — biggest trade-off: it is not a headphone. It's a pair of pads. If your headphones are wireless, on-ear, or use a proprietary mounting ring, these may simply not fit.
• Kinglucky UPGRADE Noise Cancelling — biggest strength: it's a complete package — active noise cancellation, Bluetooth 5.3, 40mm dynamic drivers, a built-in mic, up to 30 hours of playtime and a foldable frame.
• Kinglucky UPGRADE Noise Cancelling — biggest trade-off: it's a closed system. You can't re-pad or upgrade it the way you can a pair of AKG or Beyerdynamic cans.
• Pick BRAINWAVZ if you love the sound of your existing large over-ears and just want them comfortable again.
• Pick Kinglucky if you want one box that solves listening, noise and calls on the move.
The BRAINWAVZ XL Hybrid is a replacement earpad, and it's a deliberately over-built one. The outer edge is high-grade PU leather, the inner section is perforated so air can move, and the top surface that touches your head is soft velour. Underneath all of that sits memory foam. In my opinion that three-material sandwich is the whole point: velour for long-session comfort, perforated PU for breathability, memory foam for support and isolation that holds its shape instead of flattening after a few months.
The other half of the story is the mounting flap. A large flap on the rear is what lets these pads stretch across many different headphone mounting systems, and Brainwavz publishes a genuinely long compatibility list — AKG K701/K702/Q701/K712/K7XX, Audio-Technica ATH-R70X and the AD series, Beyerdynamic DT770/DT880/DT990, HiFiMan HE4XX and HE-560, plus Samson SR850, Superlux HD668B/HD681, Monoprice Monolith M1060 and more. The pads themselves measure roughly 4.33 inches across and about 1.18 inches deep, which is what "XL" and "thicker than most standard pads" mean in practice: more room between driver and ear.
So who should buy it? Anyone whose large round-cup headphones have pads that are cracked, flaking, squashed or just uncomfortable after an hour. It's also the smarter move if you like how your headphones sound and don't want to replace them. Who should skip it? If you own small on-ear headphones, a wireless model with a clipped-in proprietary pad ring, or anything not on that compatibility list, don't gamble — measure and check the list first. And if you want noise cancelling or Bluetooth, this product will never give you either.
The Kinglucky UPGRADE (model B900) is the opposite kind of purchase: a self-contained wireless headphone. Active noise cancellation is switchable, so you can mute a bus engine or an open-plan office, then flip ANC off when you'd rather hear traffic or a colleague. The drivers are 40mm dynamic units with a rated 20 Hz–20,000 Hz range, 32 ohm impedance and 112 dB sensitivity — the kind of tuning that tends to push bass forward, which matches the "booming bass" framing in the product name.
Connectivity is Bluetooth 5.3 with a stated range of about 15 meters, and there's a 3.5mm jack plus an included audio cable for wired listening when you want it. Battery is quoted at up to 30 hours of playtime with USB-C charging. The memory-foam ear cushions are called out as comfortable for glasses wearers, the headband is adjustable, and the whole thing folds for travel. Controls are button-based, and there's a built-in microphone with noise reduction for calls and meetings. It ships with the headphones, a charging cable, a 3.5mm cable and a manual, backed by a one-year manufacturer warranty.
Who should buy it? Commuters, students, remote workers and travelers who want one headphone to handle music, calls and background noise — and who don't want to think about pads, cables or compatibility lists. Who should skip it? Anyone chasing reference-grade audio, anyone who prefers an open, airy sound, and anyone who already owns a great pair of wired over-ears and only needs them comfortable again.
Side-by-Side: Which Should You Choose?
• Best for a complete out-of-the-box listening setup → Kinglucky UPGRADE Noise Cancelling. Headphones, cable, charging cable and ANC in one purchase.
• Best for noise cancelling → Kinglucky UPGRADE Noise Cancelling. It has switchable ANC; the Brainwavz pads have none.
• Best for long listening comfort on big over-ears → BRAINWAVZ XL Hybrid Memory. Velour top, perforated PU, memory foam and an extra-thick XL profile.
• Best for commuting, calls and travel → Kinglucky UPGRADE Noise Cancelling. Bluetooth 5.3, a mic, folding design and up to 30 hours of playtime.
• Best for wired purists → BRAINWAVZ XL Hybrid Memory. It keeps your existing wired headphones in service instead of replacing them.
• Best for glasses wearers → Kinglucky UPGRADE Noise Cancelling. The memory-foam cushions are specifically described as conforming comfortably for people who wear glasses.
• Best for compatibility risk → Kinglucky UPGRADE Noise Cancelling. It fits anyone; the Brainwavz pads only fit the models on its list.
I'd buy the BRAINWAVZ XL Hybrid Memory pads, and here's my reasoning: if you already own a pair of large over-ears — an AKG K7-series, a DT770, an HE4XX — the weakest link is almost always the pad, not the driver. Replacing a worn pad restores comfort, isolation and the seal that makes bass sound like bass, and the hybrid velour/PU/memory-foam build is a genuinely thoughtful design. I'd only steer you to the Kinglucky UPGRADE if you don't own good headphones yet, or you specifically need ANC, Bluetooth and a mic in one device. Check the current price on Amazon for whichever path you take, then decide.
Just earpads. It's a replacement/upgrade pad set for large over-ear headphones and includes no drivers, cable or electronics of its own.
Only if your model is round-cupped and large. Brainwavz lists AKG, Audio-Technica, Beyerdynamic, HiFiMan, Samson, Superlux, Monoprice and others — check that list before buying.
Up to 30 hours of playtime per the specs, recharged over USB-C. Actual runtime depends on volume and whether ANC is on.
Yes. It's wireless over Bluetooth 5.3, but a 3.5mm audio cable is included, so you can listen wired when you want.
They're not really comparable purchases — one is a part, one is a whole product. Decide by need first, then check the current price on Amazon for both.
