If you want the lightest possible side-sleeper earbud with a focus on pure sleep comfort, choose Kibubu Air 10; if you need a multi-purpose earbud that also handles real-time translation and longer battery life, choose MINISO MS217.
• Kibubu Air 10 — biggest strength: At roughly 2 g per earbud with a low-profile, flush-fit shape, it's built specifically for side sleepers who roll over during the night. Its 42 dB passive noise cancellation targets snoring and background hum without needing power.
• Kibubu Air 10 — biggest trade-off: No active noise cancellation and no app control. The touch controls are simple and the total playtime tops out at 25 hours, which is less than the MINISO's combined figure.
• MINISO MS217 — biggest strength: A 4-in-1 device pairing sleep noise cancellation with real-time AI translation across 165 languages, Bluetooth 6.0, and up to 48 hours total battery life. The hybrid noise cancellation is active plus passive.
• MINISO MS217 — biggest trade-off: Each earbud weighs around 3 g, and the app is required for translation and control features, which adds a setup step the Kibubu doesn't have.
• Who the Kibubu Air 10 is for: Dedicated side sleepers and light sleepers who want the smallest, lightest earbud possible for one job — sleep.
• Who the MINISO MS217 is for: Travelers, students, and shift workers who want one earbud for sleep, calls, music, and translation on the go.
The Kibubu Air 10 is a single-purpose sleep tool, and it's honest about that. Every spec points toward one goal: disappearing in your ear at night. Each earbud weighs about 2 g (the item listing puts it around 2.3–2.5 g depending on how you count), and the oval, flush-fit shape is engineered so nothing pokes out when your head hits the pillow. For side sleepers, that's the whole ballgame. A bulky bud that presses into your ear canal at 2 a.m. is why most people give up on sleep earbuds entirely.
Where the Kibubu shines beyond sleep: Bluetooth 5.4 with a 15-meter range, 50 ms latency (low enough for movies and ASMR without lip-sync drift), and a vocal-forward tuning that suits dialogue, guided meditation, and ASMR. You get 5 hours per charge plus 4 extra charges in the case for 25 hours total, and the case itself carries a 180 mAh battery with a 3-level indicator. The touch controls are straightforward.
Who should buy it: Side sleepers, light sleepers, and anyone who wants the smallest, lightest possible earbud and doesn't care about translation or active noise cancellation. Who should skip it: If you want active noise cancellation, app-based EQ, or you'll rely on these for calls and travel translation, the Kibubu isn't trying to be that device.
MINISO MS217: Who It's For
The MINISO MS217 takes the opposite approach. Instead of doing one thing, it crams four functions into a sleep-sized shell: music, calls, sleep noise cancellation, and real-time AI translation across 165 languages and 8 modes. That translation angle is genuinely unusual for a sleep earbud. You download the Saymi app (free, no subscription) and use modes like AI Conversation, Free Talk, or Translator Device. For frequent travelers or anyone working across languages, that's a real feature, not a gimmick.
On the sleep side, the MS217 pairs hybrid noise cancellation — active plus passive — with soft silicone earcaps. It's designed to reduce snoring, appliance hums, pet movement, and traffic noise. Each earbud weighs about 3 g, and like the Kibubu, it's aimed at side sleepers, light sleepers, insomniacs, shift workers, and travelers.
Battery is the MS217's headline number: nearly 8 hours per charge, stretching to 48 hours with the case, and Type-C fast charging to full in about 1.5 hours. Bluetooth 6.0 promises a more stable connection, lower latency, and reduced power draw than older versions. The audio uses Hi-Fi dynamic drivers tuned for rich bass and clear treble, and it's controlled through the app rather than touch panels.
Who should buy it: Travelers, students, shift workers, and anyone who wants one earbud to cover sleep, music, calls, and translation. Who should skip it: If you want the absolute lightest bud and don't need translation or app control, the extra 1 g per earbud and the app dependency may not be worth it to you.
Side-by-Side: Which Should You Choose?
• Best for active noise cancellation → MINISO MS217. Its hybrid ANC actively adapts to noise, while the Kibubu relies on passive sealing alone.
• Best for battery life → MINISO MS217. Up to 48 hours total versus 25 hours on the Kibubu.
• Best for translation and travel → MINISO MS217. 165 languages, 8 modes, and a free app make it a genuine multi-tool.
• Best for simple, no-app use → Kibubu Air 10. Touch controls work out of the box; nothing to install.
• Best for low-latency movie/ASMR listening → Kibubu Air 10. Its 50 ms latency and vocal-forward tuning suit dialogue and ASMR well.
• Best for calls and everyday music → MINISO MS217. Hi-Fi dynamic drivers and app control give it more flexibility across daily use.
• Best for the lightest possible weight → Kibubu Air 10. Around 2 g per bud is about as light as sleep earbuds get.
In my opinion, if you're buying these for one reason — sleeping on your side without a hard lump digging into your ear — I'd go with the Kibubu Air 10. It's lighter, it's simpler, and its whole design is pointed at that single job. The trade-off is real: no active noise cancellation, no translation, and less total battery. But if sleep is the mission, that's a trade I'd happily make. If you want one earbud to do sleep, calls, music, and translation, I'd pick the MINISO MS217 instead.

Both are designed for side sleepers. The Kibubu Air 10 is lighter at around 2 g per earbud with a flush oval fit, while the MINISO MS217 is about 3 g with silicone earcaps. For pure minimal bulk, the Kibubu has the edge; for silicone grip and active noise cancellation, the MINISO does.
Yes, per its specifications it supports real-time translation across 165 languages with 8 modes through the free Saymi app, and no subscription is required. The Kibubu Air 10 has no translation feature at all.
The Kibubu uses 42 dB passive noise cancellation only, relying on ear-tip sealing. The MINISO MS217 uses hybrid noise cancellation, combining active and passive. For steady background noise like humming appliances, the MINISO's active system is the more adaptable choice.
The Kibubu Air 10 offers about 5 hours per charge and 25 hours total with its case. The MINISO MS217 offers nearly 8 hours per charge and up to 48 hours total, with Type-C fast charging to full in roughly 1.5 hours.
