How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a low-profile in-ear bud built specifically for side sleepers, choose Medocis Sleep Earbuds; if you need an open-ear hook design with huge battery life, waterproofing and a built-in translation feature, choose MINISO X15PRO. These two look like they compete for the same buyer, but they solve completely different problems. One is about lying on your pillow without pain. The other is about staying awake, moving, and understanding people around you.
• Medocis Sleep Earbuds — biggest strength: the asymmetric chamber with geometric airflow channels, designed so side sleepers can rest on one ear without the bud digging into the pillow.
• Medocis Sleep Earbuds — biggest trade-off: battery life is rated at about 4 hours per charge, with a 1-hour charge time, so it's a single-session bud, not a multi-day one. It also uses passive noise cancellation only.
• MINISO X15PRO — biggest strength: up to 40 hours of total playback with the charging case, plus IPX5 waterproofing and an app-based translation feature covering 165 languages.
• MINISO X15PRO — biggest trade-off: it's an open-ear hook design, so it deliberately doesn't seal your ear canal and offers no noise control at all — meaning background sound comes in.
• Who Medocis is for: sleepers, side-sleepers, and anyone who wants a discreet in-ear bud for quiet listening in bed or at a desk.
• Who MINISO X15PRO is for: runners, gym-goers, commuters, travellers and language learners who want long runtime and to stay aware of their surroundings.
The Medocis Sleep Earbuds are built around one very specific design decision: the asymmetric chamber. Instead of a symmetric bud that presses into your ear when you roll onto your side, the housing is shaped to sit flatter, with geometric channels that let air move through. That airflow detail matters more than it sounds. A lot of in-ear buds get uncomfortable not because they're heavy but because heat and pressure build up against the ear. Medocis addresses that directly, and it's the reason this is one of the few in-ear designs I'd genuinely describe as sleep-oriented.
The rest of the spec sheet supports the same story. The buds are a micro form factor with a 6 mm dynamic driver and a polymer diaphragm, and the enclosure is listed as frosted white polymer. The carrying case is small and light — roughly 2.17 inches square, under an inch thick, about 1.1 ounces — and it opens with a slide mechanism rather than a flip lid, with an LED digital display on the case to show battery status. Bluetooth 5.4 handles the connection with a 10-meter range, there's a built-in mic for calls, and controls are touch-based. Impedance is 32 ohm with a 20Hz–20,000Hz range.
Where it asks you to compromise is runtime and noise. Battery life is rated at 4 hours, and a full charge takes about an hour. Noise control is passive only, meaning the fit itself does the blocking rather than any active cancellation. So if you want a bud you can wear for eight hours straight or use to drown out a plane cabin, this isn't that product.
Who should buy it: side sleepers, people who listen to podcasts or quiet music in bed, and anyone who wants a small, light in-ear bud with a modern case and touch controls. Who should skip it: long-haul travellers, marathon listeners, and anyone who needs active noise cancellation or all-day battery.
The MINISO X15PRO goes the opposite direction. It's an open-ear hook design, which means the bud rests outside your ear canal rather than inside it. Nothing plugs your ear, so you keep hearing traffic, gym noise, announcements and the people around you. The ergonomic earhook is described as ultra-light with a zero-pressure feel, designed to stay put during running, sports and commuting. The housing is black ABS plastic, and the package includes the charging case, a lanyard, a USB-C charging cable and a manual.
The headline number here is battery: up to 40 hours of total playback with the case, supported by fast charging. That's a completely different class of runtime from the Medocis. It also carries an IPX5 waterproof and sweatproof rating, which makes it a realistic option for running, gym sessions, hiking and light rain. On the audio side, MINISO lists a dynamic driver with 16 ohm impedance, described as HiFi stereo for music and calls, and the buds use Bluetooth 6.0 for pairing, with a 10-meter range. Controls are touch-based. Notably, noise control is listed as none — that's the open-ear trade-off, and it's worth being clear about it.
Then there's the feature that makes this product unusual: AI translation. Through the dedicated SayMi app, the X15PRO supports two-way online translation across up to 165 languages, with no subscription and no hidden fees. The important caveat, straight from the product's own notes, is that it requires the app plus a Wi-Fi or cellular connection — there's no offline translation — and it's intended for casual daily conversations, not professional high-precision interpreting.
Who should buy it: runners, gym users, cyclists, commuters, frequent travellers and casual language learners who want long battery life and ambient awareness. Who should skip it: anyone who wants isolation, deep bass from a sealed fit, or reliable translation in a professional or offline setting.
• Best for sleeping on your side → Medocis Sleep Earbuds. The asymmetric chamber and airflow channels exist for exactly this; the X15PRO's earhook is not designed to be pressed against a pillow.
• Best for battery life → MINISO X15PRO. Up to 40 hours with the case versus roughly 4 hours per charge on the Medocis.
• Best for workouts and sweat → MINISO X15PRO. IPX5 waterproof and sweatproof, with an earhook that's built to stay on while you move.
• Best for staying aware of your surroundings → MINISO X15PRO. Open-ear means no canal blockage, so traffic and conversation come through.
• Best for quiet, isolated listening → Medocis Sleep Earbuds. Passive noise cancellation plus an in-ear seal does more blocking than an open-ear hook ever will.
• Best for travel and language learning → MINISO X15PRO. The SayMi app translation across 165 languages is a real differentiator for trips — just remember it needs a live connection.
• Best for a discreet, low-profile fit → Medocis Sleep Earbuds. A micro in-ear bud with a compact slide-open case is far less visible than an earhook.
• Best for charging convenience → Medocis Sleep Earbuds. The LED digital display on the case tells you the battery state at a glance, which the X15PRO doesn't offer.
If I had to pick one, I'd buy the MINISO X15PRO — because it covers more of everyday life. Forty hours of playback with the case, IPX5 protection, an earhook that stays put during runs, and a translation feature you'll actually use on a trip add up to a more versatile product for most people. In my opinion, the Medocis Sleep Earbuds are the better choice only if sleep is your specific goal: if you're a side sleeper who wants a small in-ear bud that doesn't press into your ear at night, that asymmetric chamber is the reason to choose it. Buy for the job you actually need done. And since neither product's value depends on specs alone, check the current price on Amazon before you commit.
FAQ
Not really. It's an open-ear earhook design meant for sports, commuting and travel. The hook shape isn't built to lie flat against a pillow, so side sleepers will likely find the Medocis design more comfortable.
They use passive noise cancellation, which means the in-ear fit physically blocks some sound rather than using active electronics. There's no active ANC mode. The MINISO X15PRO lists no noise control at all.
No. Translation requires the SayMi app, a paired phone and a Wi-Fi or cellular connection — there's no offline mode. It's designed for casual daily conversations, not professional interpreting, and there's no subscription fee to use it.
The MINISO X15PRO, clearly. It's rated up to 40 hours of total playback with the charging case, while the Medocis Sleep Earbuds are rated around 4 hours of battery life with an approximately 1-hour charge time.
