• ALXCD Foam Ear Tips — biggest strength: Soft memory foam with a sound-isolating design that reduces ambient noise, sold in three sizes (S/M/L) with three pairs per pack, plus a fiber cloth.
• ALXCD Foam Ear Tips — biggest trade-off: It only fits the Sony WF-1000XM4, so it does nothing for any other headphone or earbud.
• SOULWIT Earpads Replacement — biggest strength: Protein leather over high-density memory foam, tailored specifically for the AVENTHO 300 over-ear headphones, with an install guide included.
• SOULWIT Earpads Replacement — biggest trade-off: Compatibility is exclusive to the Beyerdynamic AVENTHO 300, and the manufacturer lists no warranty.
• Who ALXCD is for: WF-1000XM4 owners who want a snugger, more isolating in-ear fit.
• Who SOULWIT is for: AVENTHO 300 owners whose original pads are flattened, cracked or just uncomfortable.
This is a small accessory with one clear job. ALXCD makes foam tips that are compatible with the Sony WF-1000XM4 earbuds, and the material is memory foam — the silver-colored, squish-and-expand kind that molds itself to the shape of your ear canal once it warms up. That's the whole pitch, and honestly, it's a good one for the right buyer.
The sound-isolating design is the part I'd focus on. Foam doesn't just sit in your ear the way a silicone tip does; it fills the space, which is why foam is the go-to material when you want to block ambient noise for high-intensity listening. If you game on Xbox with a controller in your hands and a fan or a TV humming in the background, that extra seal is exactly what you're chasing. You get three sizes — small, medium and large — in the pack, with three pairs total, so you can find the fit that stays put and keep spares. There's also a small fiber cloth with the ALXCD logo included, which is a nice touch for keeping the tips clean.
Who should buy it: WF-1000XM4 owners who find their current tips slipping, leaking sound, or letting too much room noise in. Who should skip it: anyone who doesn't own the WF-1000XM4. This is a model-specific part — it won't fit other earbuds, and it certainly won't help over-ear headphones. If you're the type who swaps tips constantly and wants a wide size range, three sizes is reasonable but not exhaustive. And remember these are consumable — foam compresses over time, so treat them as something you'll replace rather than something you'll keep forever.
The SOULWIT Earpads Replacement is a different animal entirely. This is a full replacement cushion set for the Beyerdynamic AVENTHO 300 Wireless Over-Ear headphones, built from protein leather wrapped around high-density memory foam, in black. If your AVENTHO 300 pads have gone flat, started flaking, or simply stopped feeling comfortable after a lot of hours on your head, this is the part that brings them back.
The materials matter here. Protein leather is the soft, smooth-facing surface a lot of headphone makers use on pads because it wipes clean easily and feels supple against the skin. High-density memory foam is the layer underneath — the denser the foam, the less it collapses under the weight of the headband, which is usually what makes old pads feel like they've disappeared. Combining the two is the standard recipe for over-ear comfort, and SOULWIT follows it. Installation is described as straightforward with a clear guide included, and the brand positions the pads as a way to refresh the look of your headphones and make them feel new again.
Who should buy it: AVENTHO 300 owners who want to extend the life of a headphone they already like rather than replace the whole thing. Who should skip it: anyone whose headphones aren't the AVENTHO 300. The compatibility is exclusive and the product page says to verify your model before buying — take that seriously. Also note the manufacturer lists no warranty, so you're relying on the build quality itself. If you're comfortable swapping pads (most over-ear pads pop or stretch into a groove, and SOULWIT includes guidance), this is a low-drama upgrade. If you're not, budget a few minutes and some patience.
• Best for blocking room noise on an Xbox setup → ALXCD Foam Ear Tips. The sound-isolating foam design is built for exactly that.
• Best for restoring an existing pair of over-ear headphones → SOULWIT Earpads Replacement. It's a direct cushion swap for the AVENTHO 300.
• Best for fit tuning → ALXCD Foam Ear Tips. Three sizes (S/M/L) and three pairs let you dial in the seal.
• Best for long-session comfort on over-ears → SOULWIT Earpads Replacement. Protein leather plus high-density memory foam is the comfort-first combination.
• Best for an in-ear solution → ALXCD Foam Ear Tips. It's designed for the WF-1000XM4 and nothing else.
• Best for a single-model over-ear refresh → SOULWIT Earpads Replacement. Exclusive fit, clear install guide, no guesswork about which headphone it's for.
• Best for buyers who want spares on hand → ALXCD Foam Ear Tips. Three pairs means you're not stuck if one compresses or tears.
• Best for appearance refresh → SOULWIT Earpads Replacement. New pads change how a well-used headphone looks, not just how it feels.
In my opinion, the right pick comes down to which headphones you already own — the two products don't compete for the same buyer. If you have Sony WF-1000XM4 earbuds and you game on Xbox, I'd buy the ALXCD Foam Ear Tips: the memory foam seal is the single biggest thing you can change about how isolated your in-ears feel, and three sizes plus spares is a sensible way to get there. If you have Beyerdynamic AVENTHO 300 over-ear headphones with tired pads, I'd buy the SOULWIT Earpads Replacement instead — protein leather and high-density memory foam are the right materials to make a long session comfortable again. For Xbox specifically, foam tips fix the in-ear experience; replacement pads fix the over-ear one.
can you sleep with over ear headphones
You can physically wear over-ear headphones lying down, but it's not ideal — the headband and cups press against your head and the pillow, and the clamping force of pads like the SOULWIT set will feel heavier over time. If you want to listen in bed, in-ear tips that sit flush, like the ALXCD foam tips, are usually the more practical choice.
how to wear over ear headphones
Put them on with the headband over the crown of your head and the cups centered over your ears, not sitting on them. The L and R markings on the cups tell you which side is which. Once on, adjust the sliders so the headband rests lightly and the pads seal around your ears evenly.

how should over ear headphones fit
They should feel gently secure: enough pressure that they don't slide when you move, but not so much that your head aches after an hour. The pads should fully cover your ears. If you can feel the driver pressing against your ear, or the pads have gone flat and hard, the cushions are the problem, not the fit.
