If you want a compact, multi-device cleaning tool for study, choose Hyashee Cleaner Kit; if you need an AirPods Pro case with a cleaning pen included, choose KOUJAON Compatible. Hyashee is the more focused pick for cleaning earbuds and other small electronics. KOUJAON combines a cleaner with a silicone case and decorative keychain.
• Hyashee Cleaner Kit’s biggest strength: a pen-style, three-part tool for cleaning earbud details and other small electronics. Trade-off: it does not include a protective AirPods case.
• KOUJAON Compatible’s biggest strength: a silicone case, bling flower keychain, and three-part cleaning pen in one package. Trade-off: its case is designed for specified AirPods Pro charging cases, not for general use.
• Hyashee suits people who want a portable cleaner they can use on earbuds, keyboards, phones, and other small devices.
• KOUJAON suits people who want to protect a compatible AirPods Pro case and prefer having a keychain-style accessory.
• For a study setup, Hyashee is the simpler choice if cleaning is the main job; KOUJAON makes more sense if case protection is part of the goal.
Hyashee is a compact cleaning pen with three distinct tools: a precision metal tip, a soft brush, and a flocking sponge. The metal tip is intended for stubborn dirt in small gaps, while the brush is suited to mesh and speaker areas. The sponge can help reach charging-case corners. That mix makes it a focused option for someone who wants one small tool for routine earbud upkeep.
Its usefulness is not limited to AirPods. The listed uses include wireless earbuds, Bluetooth headphones, phones, tablets, keyboards, cameras, and smartwatches. At 18 grams, with a pen-style design, it is easy to keep in a desk drawer or carry with everyday gear. That portability could be handy during a long study day when earbuds and a keyboard are both in regular use.
I’d choose Hyashee if cleaning is the priority and I want a tool that can handle more than one kind of device. I’d skip it if I’m looking for a protective case, since the kit does not include one. The metal tip is intended for detailed cleaning, but delicate mesh and surfaces call for a careful touch; the soft brush is the more appropriate part for those areas.

KOUJAON combines a silicone protective case for specified AirPods Pro charging cases with a three-part cleaning pen and a five-leaf bling flower keychain. The silicone case is intended to help protect against bumps, drops, and scratches, and its material is described as washable. The keychain can attach to a key, belt, or bag, which may make the case easier to locate among other belongings.
The compatibility details matter here: the cover is listed for AirPods Pro 2nd Generation, including USB-C and Lightning versions, and AirPods Pro 1st Generation. The AirPods charging case itself is not included. The cleaning pen has a metal tip, soft brush, and flocking brush, so it covers the same general cleaning roles as Hyashee while adding a case and keychain.
I’d consider KOUJAON if I own one of the specified AirPods Pro cases and want protection plus a cleaner in the same package. I’d skip it if I need a cleaner for a wider range of electronics, or if I don’t want a pink case and decorative keychain. Its included cleaner is part of a case-focused bundle, not a stand-alone, multi-device cleaning kit.
• Best for cleaning several kinds of electronics → Hyashee Cleaner Kit. Its listed uses extend beyond earbuds to phones, tablets, keyboards, cameras, and smartwatches.
• Best for a compatible AirPods Pro charging case → KOUJAON Compatible. The silicone cover is designed for specified first- and second-generation Pro cases.
• Best for a portable cleaning pen → Hyashee Cleaner Kit. Its compact pen-style form is suited to a desk drawer, bag, or travel kit.
• Best for combining cleaning with case protection → KOUJAON Compatible. It includes both a cleaning pen and a washable silicone cover.
• Best for reaching earbud mesh and speaker areas → Either, with care. Both include a soft brush; Hyashee also specifies a flocking sponge for case corners, while KOUJAON lists a flocking brush.
• Best for organizing or spotting an AirPods case in a bag → KOUJAON Compatible. Its keychain can attach to bags or other items.
• Best if you don’t own compatible AirPods Pro earbuds → Hyashee Cleaner Kit. Its uses are broader and are not limited to a particular charging-case model.
• Best if the cleaner is the only thing you need → Hyashee Cleaner Kit. KOUJAON’s main added purpose is its model-specific protective case and keychain.
The naming can make these two sound like direct alternatives, but they are not quite the same kind of purchase. Both include a three-part cleaning pen. Hyashee puts the emphasis on the cleaning tool itself; KOUJAON adds protection and carrying convenience for a narrower set of earbuds. So the deciding question is less about which pen has more parts and more about whether the case is useful to you.
If you’re trying to find the best over ear headphones for study or noise cancelling in ear earbuds for study, neither item is a headphone product. They are cleaning and case accessories. Either could be relevant to maintaining compatible earbuds, but neither adds noise cancelling, changes how headphones fit, or creates a transparency mode. For shoppers looking for the best transparency mode headphone for study, these products do not address that feature.
I would buy Hyashee Cleaner Kit if I wanted a practical cleaning tool for study gear, because it is portable and its listed uses cover earbuds as well as other small electronics. It is the more straightforward choice when cleaning is the main need.
I’d choose KOUJAON instead if I owned a compatible AirPods Pro case and specifically wanted the silicone cover and keychain. My pick for study is Hyashee; my pick for a combined case-and-cleaner bundle is KOUJAON.
