If you want soft, corded silicone earplugs for sleep and quiet, choose MUCKLILY Noise Cancelling Silicone; if you need replacement tips for Soundcore Sleep A20 or A30 earbuds, choose Klowcok Replacement Ear Tips. For a big head, neither is an over-ear headphone: the choice is between a standalone corded pair and replacement tips for compatible earbuds.
MUCKLILY Noise Cancelling Silicone vs Klowcok Replacement Ear Tips at a Glance
• Klowcok’s biggest strength: six pairs of silicone tips in S/M/L, made to replace tips on Soundcore Sleep A20 or A30 earbuds. Trade-off: earbuds are not included, and these tips are not presented as a standalone listening product.
• Choose MUCKLILY if you want corded earplugs for reducing noise around you; choose Klowcok if you already own compatible Soundcore sleep earbuds and need replacement tips.
MUCKLILY is a standalone, corded silicone product aimed at reducing surrounding noise for sleep, study, travel, and relaxation. Its soft, flexible material and ergonomic design are intended to support a comfortable fit over longer periods. The cord is a practical distinction for someone who wants the two pieces connected rather than loose in a pocket or beside the bed.
That makes MUCKLILY the more relevant option if you are looking for something to wear while trying to rest through snoring or concentrate in a noisy environment. It is compact and lightweight, so the described use cases include carrying it for travel or keeping it handy for meditation and quiet time. The product information identifies the material as silicone and the style as corded.
Skip MUCKLILY if what you actually need is a replacement part for Soundcore Sleep A20 or A30 earbuds. The supplied details do not list compatibility with those earbuds or specify a set of multiple tip sizes. Also, despite searches such as “best waterproof head phones for big head,” this is not described as headphones, sports earbuds, or a waterproof product. It is better understood as corded noise-isolating silicone earplugs.
Klowcok is a replacement-tip set for Soundcore Sleep A20 and A30 earbuds. It includes six pairs: two pairs each in S, M, and L. That range gives owners of those earbuds a choice of tip sizes, while the soft, lightweight silicone and easy-replacement design are intended to help the tips fit securely and block noise.

The strongest reason to choose Klowcok is straightforward: you already have compatible Soundcore sleep earbuds and need fresh tips or want to try a different size. The three included sizes make it more adaptable than a set that offers only one listed size. The tips are also described as washable, which may suit someone who wants removable parts they can clean.
This is not a complete pair of earbuds. The earphones are not included, and compatibility is specifically stated for Soundcore Sleep A20 and A30. If you want a standalone product for sleep or a corded option to keep the pieces connected, Klowcok does not fill that role. Its job is to replace the tips on the compatible earbuds you already own.
• Best for standalone noise isolation during sleep or study → MUCKLILY. It is described as a corded silicone product for sleep, snoring, travel, and focus.
• Best for replacing Soundcore Sleep A20 or A30 tips → Klowcok. Its stated compatibility is the key reason to choose it.
• Best for choosing among tip sizes → Klowcok. The package includes S, M, and L, with two pairs of each.
• Best if you want the pieces connected by a cord → MUCKLILY. Its corded style distinguishes it from replacement tips.
• Best if you already own Soundcore sleep earbuds → Klowcok. These are replacement parts, not a separate listening device.
• Best for a lightweight, soft-silicone option → Either, for different purposes. Both use silicone and are described as lightweight or soft; MUCKLILY is corded ear protection, while Klowcok is a set of earbud tips.
• Best sports earbuds for a big head → Neither based on the listed details. Neither product is described as sports earbuds, and neither provides headband or over-ear fit information.
• Best USB-C charging sports earbuds for a big head → Neither. No earbuds, charging port, battery, or USB-C feature is specified for either product.
These distinctions matter more than trying to treat the products as direct substitutes. MUCKLILY is intended to sit in your ears as a corded noise-isolating option. Klowcok attaches to particular earbuds and depends on those earbuds for its use. One is not an alternative set of earbud tips, and the other is not a complete pair of sleep earbuds.
For a big head, that distinction is especially useful. Neither product has a headband or an over-ear frame whose fit would depend on head circumference. If your search for headphones for a big head is really about finding something that does not squeeze around your head, these in-ear options avoid that particular fit question—but the information provided does not establish a specific fit for any individual ear.
It is also worth being precise about “noise cancelling.” The products are described in terms of noise isolation or noise blocking. The supplied information does not identify electronic active noise cancellation, microphones, or an audio system. MUCKLILY’s stated purpose is reducing surrounding noise; Klowcok’s tips are intended to help block noise when used with compatible earbuds. Neither should be mistaken for a complete set of active-noise-cancelling headphones.
For a big head, I would choose MUCKLILY if my goal were a standalone, corded option for sleep, travel, or quiet focus. I would choose Klowcok only if I already owned Soundcore Sleep A20 or A30 earbuds and needed replacement tips in more than one size. My pick for the broader standalone use case is MUCKLILY, because it does not depend on owning a specific earbud model.
