If you want to refresh a pair of Bose over-ear headphones you already own with plusher memory foam and a thicker cushion, choose WC PadZ QC35; if you need a complete lightweight open-back headphone for all-day, multi-device listening, choose okcsc G40.
• WC PadZ QC35 — biggest strength: Replacement ear pads built from softer faux leather and memory foam with added thickness, made to fit a long list of Bose over-ear models and feel soft from the first wear.
• WC PadZ QC35 — biggest trade-off: It is not a headphone. It is a pad kit, so it only makes sense if you already own one of the compatible Bose models.
• okcsc G40 — biggest strength: A full wired headphone with 40mm dynamic drivers, a detachable MMCX cable system (3.5mm / 4.4mm / Type-C with mic) and a 113g foldable frame.
• okcsc G40 — biggest trade-off: Open-ear design with no noise cancelling and no wireless — it leaks sound and needs a cable.
• Buy WC PadZ QC35 if you own Bose QC35/QC35ii (or another listed Bose over-ear) and want to restore comfort and seal.
• Buy okcsc G40 if you want a complete, portable, open-ear headphone for commuting, campus and gaming across several devices.
The WC PadZ QC35 is a memory foam over-ear pad kit, not a headphone. You get a pair of replacement cushions in black faux leather with a memory foam core, plus an instruction manual and a step-by-step guide. Wicked Cushions designed them to fit a specific list of Bose over-ear models: QuietComfort 35 and 35ii, QC25, QC15, QC2, AE2, AE2i, AE2w, SoundTrue and SoundLink. If your model is not on that list, this is not the pad for you — the fit is model-specific by design.
What stands out in the specs is the comfort-first build. The leather is described as a new, softer formulation paired with memory foam, and the pads are made thicker than stock. The point of that extra thickness is twofold: it keeps your ears from pressing against the driver housing, and it helps the pad conform around your ear to improve the seal. A better seal means less outside noise creeping in and more of the low end you remember from your headphones. Wicked Cushions also claims these feel soft from day one rather than needing a break-in period.
Durability is the other theme. The inside seams are stitched and reinforced with glue to stop the cushion from splitting, which is the classic failure point on worn-out pads. You also get a 365-day full warranty. In my opinion, this is the sensible buy for anyone whose Bose pads have flattened, peeled or gone shiny with age but whose headphones themselves still work fine. Skip it if you do not own a listed Bose model, if you want a whole new headphone, or if you prefer a thinner, more factory-original profile — the added thickness is a deliberate change, not a match to stock.
The okcsc G40 is a completely different animal: a wired, open-back, retro-styled headphone. The core is a 40mm dynamic driver rated 16 ohm and 101 dB across a 20Hz–20,000Hz range. Low impedance and high sensitivity like that generally means it is easy to drive straight from a phone or laptop jack without a separate amp. The tuning is described as crisp highs, warm mids and deep bass — a casual-listening profile aimed at music fans, students and casual gamers rather than studio engineers.
The design is the real story. It is an open-ear headphone, meaning the cups do not seal over your ears. That keeps ears cool and breathable, and okcsc rates it for 8-hour pain-free wear — good for group study, long commutes and outdoor hangouts where stuffy closed cups get uncomfortable. The trade-offs are honest ones: open-back means sound leaks out and outside noise leaks in, and there is no noise cancelling at all. It is also wired-only.
Where it earns its keep is portability and flexibility. The frame is 113g and foldable, with a stainless steel headband and aluminum alloy shell that okcsc says resists drops and scratches. The cable is detachable MMCX in 3.5mm, 4.4mm and Type-C (with mic) versions, so you can swap between phone, laptop and console without changing headphones. A carry bag is included, and there is a 1-year warranty. I would steer toward the G40 if you want one light headphone that moves between devices and survives a backpack. I would steer away if you need isolation on a plane, want wireless freedom, or expect deep sub-bass from a sealed cup.
Side-by-Side: Which Should You Choose?
• Best for reviving headphones you already own → WC PadZ QC35. It is a repair-and-upgrade part, not a new set.
• Best for a complete headphone out of the box → okcsc G40. Drivers, cable, pads, case — everything is included.
• Best for all-day cool wear → okcsc G40. The open-ear design is built for 8-hour sessions without heat build-up.
• Best for multi-device switching → okcsc G40. Detachable 3.5mm, 4.4mm and Type-C (with mic) cable options.
• Best for travel and portability → okcsc G40. 113g, foldable, with a storage bag.
• Best for noise blocking → WC PadZ QC35. A thicker, conforming pad improves the seal on your Bose cups; the G40 has none by design.
• Best for durability against drops → okcsc G40. Stainless steel headband and aluminum alloy shell.
• Best for people who do not own Bose → okcsc G40. The pad kit only fits the listed Bose models.
In my opinion, these two should not be weighed against each other as rivals — they solve different problems. If you already own Bose QC35 or another listed Bose over-ear and the pads have worn out, I would buy the WC PadZ QC35. It is the cheaper-feeling path to better comfort and a tighter seal, and it keeps a headphone you already like alive. If you need an actual headphone — light, wired, open-ear, multi-device — I would buy the okcsc G40 instead. Pick based on what is missing from your setup, not on which one sounds better on paper. And check the current price on Amazon before you commit, since both sit in very different budget brackets.
can you sleep with over ear headphones
You can, but it is not ideal. The WC PadZ QC35's thicker memory foam cushions make lying down more comfortable than flattened stock pads, while the okcsc G40's 113g open-ear frame is lighter but its stainless steel headband and aluminum shell can dig in against a pillow. Neither product is designed specifically for sleep.
how to wear over ear headphones
Slide the headband over your head so each cup sits centered over an ear, then adjust the sliders for a snug but not tight fit. With the WC PadZ QC35, the thicker memory foam should conform around your ear and create a seal. With the okcsc G40, the open-ear cups rest against the ear rather than sealing, so expect some sound leakage both ways.
how should over ear headphones fit
The cups should surround your ears without pressing them flat, and the headband should sit with even pressure and no hot spots. The WC PadZ QC35 is built thicker to relieve pressure on the ear itself and improve the seal, while the okcsc G40 is designed for a light, breathable 8-hour fit with a foldable, 113g frame.
how to wear over ear headphones properly
Center the cups, adjust each side evenly, and check that the cable is not pulling on the cups. On the okcsc G40 the MMCX cable is detachable, so make sure it is fully seated in 3.5mm, 4.4mm or Type-C mode before you move around. On the WC PadZ QC35, follow the included step-by-step guide so the new pads seat correctly and do not pinch.
