If you want reusable, standalone ear plugs for airplane noise and sleeping, choose Afflatus Ear Plugs; if you need replacement tips for compatible Soundcore Sleep A20 or A30 earbuds, choose Klowcok Replacement Ear Tips. These products serve different purposes: Afflatus is a complete pair of ear plugs, while Klowcok is a set of silicone tips that does not include earbuds.
For airplane travel, I’d choose based on whether you want simple sound reduction without an earbud or need to refresh the fit of your existing Soundcore Sleep earbuds. Neither product is a complete wireless-earbud solution, so the distinction matters.
• Afflatus strength: Standalone, reusable silicone ear plugs with a non-in-ear design and up to 26 dB noise reduction. Trade-off: They reduce sound; they do not provide wireless audio or active noise cancellation.
• Klowcok strength: Six pairs of soft silicone replacement tips in S, M, and L for compatible Soundcore Sleep A20 or A30 earbuds. Trade-off: The earbuds are not included, and the tips are not described as a standalone hearing protector.
• Choose Afflatus if you want a simple, washable ear plug for sleep, travel, or reducing unwanted noise without using an earbud.
• Choose Klowcok if you already own compatible Soundcore Sleep earbuds and need replacement tips in multiple sizes.
Afflatus is the more direct fit for someone who wants to reduce surrounding sound without wearing an earbud. Its silicone design sits outside the ear canal rather than going into it, and the product is intended to fit around the ear’s shape. That design may appeal to people who dislike the sensation of conventional in-ear plugs or want something intended for side sleeping.
The stated noise reduction is up to 26 dB, not total silence. The plugs come as two pairs in two sizes, S and L, and are washable and reusable. For airplane travel, that makes them a straightforward option if your main goal is to soften cabin noise and you do not need audio playback. They may also suit someone looking for a sleep-focused ear plug at home, including when sharing a room with a snoring partner.
Skip Afflatus if what you really want is a wireless listening device, a replacement part for Soundcore Sleep earbuds, or active noise cancellation. The product information describes passive noise reduction, not electronic cancellation. The two included sizes also do not offer the same range of options as Klowcok’s three-size assortment. And because the product is not designed to make sound disappear completely, it is not the right expectation if you need silence.

Klowcok is a replacement-part purchase, not a set of earbuds. It includes six pairs of silicone tips across S, M, and L, with two pairs of each size. The tips are intended for Soundcore Sleep A20 or A30 earbuds, so the first question is compatibility: if you do not have one of those earbuds, this set is not a substitute for a standalone ear plug.
Its appeal is practical. A selection of three sizes can help a compatible-earbud owner replace worn or missing tips or try another fit. The material is described as soft, lightweight silicone, and the tips are intended to be easy to replace and to provide noise isolation. For someone who already uses the compatible earbuds for airplane listening or sleep, fresh tips may be the useful part of the setup.
Skip Klowcok if you need ear plugs on their own. The earbuds are not included, and the product’s noise-blocking role is tied to its use as an earbud tip. It is also not a direct answer to the search for the best noise canceling wireless earbuds for airplane: these tips do not add wireless playback or active noise cancellation by themselves. They are a replacement accessory for a specific device family.
• Best for standalone airplane sound reduction → Afflatus Ear Plugs. They are complete ear plugs, with noise reduction stated up to 26 dB; Klowcok is only a set of tips.
• Best for replacing tips on Soundcore Sleep A20 or A30 → Klowcok. Those are the compatible earbud models specified for the tips.
• Best if you do not own compatible earbuds → Afflatus. Klowcok requires a separate, compatible earbud set to serve its intended purpose.
• Best for trying multiple tip sizes → Klowcok. It includes S, M, and L, with two pairs of each size. Afflatus includes S and L.
• Best for a non-in-ear design → Afflatus. Its design is described as sitting outside the ear canal rather than entering it.
• Best for refreshing an existing sleep-earbud setup → Klowcok. Replacing the tips lets you keep using the compatible earbuds you already own.
• Best for a simple reusable option for sleep or travel → Afflatus. The plugs are washable and reusable, and the product is intended for uses including sleep and flying.
• Best if you want headphones for airplane listening → Neither on its own. Afflatus provides sound reduction without audio, while Klowcok supplies tips only; you need compatible earbuds or another listening device for playback.
One distinction is easy to miss: Klowcok may be part of an airplane listening setup, but it is not itself an earbud. Likewise, Afflatus is designed to reduce sound, but it does not turn into headphones when you board. If your travel routine involves listening to music or spoken audio, consider whether you want a separate listening device in addition to sound-reducing plugs.
The fit question also points in different directions. Afflatus offers two sizes and a non-in-ear shape, which may suit someone who finds canal-style plugs uncomfortable. Klowcok offers three sizes, but those sizes are tips for compatible earbuds; they matter only if you own the matching device. Neither set’s sizing details establish that a particular fit will work for every person, so the relevant choice is the design you can actually use.
For a traveler comparing noise cancelling head phones for airplane, neither item should be mistaken for a complete active-noise-canceling headset. Afflatus is a passive ear plug with a stated maximum noise reduction figure. Klowcok is a replaceable silicone component that can be used with compatible Soundcore Sleep earbuds. If your priority is reducing noise without electronics, Afflatus is the direct option. If your priority is maintaining your existing earbud setup, Klowcok makes more sense.
I’d choose Afflatus Ear Plugs for airplane travel if my main goal were simple sound reduction without earbuds. They are a complete, washable set, and the stated noise reduction gives a concrete point of comparison. I’d choose Klowcok only if I already owned compatible Soundcore Sleep A20 or A30 earbuds and needed replacement tips. For a traveler who wants to listen to audio, I’d treat either product as only one part of the setup—not as a complete pair of wireless headphones.
Afflatus is the standalone option and is stated to reduce noise by up to 26 dB. Klowcok provides replacement tips for compatible Soundcore Sleep earbuds; the earbuds themselves are not included.
No. The set contains six pairs of silicone tips in S, M, and L. It is intended for Soundcore Sleep A20 or A30 earbuds, which must be obtained separately.
No. The product information states noise reduction up to 26 dB, not total silence. They are intended to reduce unwanted sound rather than eliminate it completely.
Klowcok includes S, M, and L, with two pairs of each size. Afflatus includes two pairs in S and L. Klowcok’s sizes are replacement earbud tips, while Afflatus’s are standalone ear plugs.
