If you want to protect a pair of Oladance OWS Pro open-ear earbuds you already own, choose DAYJOY Soft Silicone Protective; if you need a set of open-wear earbuds that translates 144 languages in real time, choose Merryking AI Language Translator.
• DAYJOY Soft Silicone Protective — biggest strength: a soft silicone skin sleeve built specifically for the Oladance OWS Pro, with a charging cutout, an anti-lost carabiner and a lanyard for outdoor carry.
• DAYJOY Soft Silicone Protective — biggest trade-off: it is a case only. There is no electronics inside, it is not water resistant, and it fits the OWS Pro alone — not the OWS 1 or OWS 2.
• Merryking AI Language Translator — biggest strength: a 3-in-1 open-wear earbud that does real-time two-way translation across 144 languages and accents, plus music and calls, with 8 languages working offline for free.
• Merryking AI Language Translator — biggest trade-off: the other 136 languages need a connection or an in-app purchase, and listening time is listed at up to 4 hours per charge.
• Who each pick is for: DAYJOY is for an existing Oladance OWS Pro owner who wants drop protection and a way to clip the earbuds to a bag. Merryking is for a traveler, student or business user who wants translation in their ears rather than in a separate handheld device.
This is a protective sleeve, not a gadget. The DAYJOY case is made of soft silicone and the brand describes it as scratch proof, shock proof, anti-skidding and durable, which is exactly what you want around a pair of open-ear earbuds that live in a bag or get tossed into a jacket pocket. The material is soft rather than rigid, so it flexes instead of cracking, and the surface grip matters more than it sounds: open-ear earbuds are worn on the ear rather than pushed into the canal, so they get set down on tables and benches constantly. A grippy skin reduces the odds of them sliding off an edge.
The practical details are the reason I'd point an OWS Pro owner here. There is a cutout in the bottom of the sleeve, so you can charge the earbuds without peeling the cover off every time. That single design decision is the difference between a case you actually keep on and one that ends up in a drawer. The package includes the silicone protective case, a carabiner and a lanyard, so you get two carry options out of the box: clip it to a backpack loop or handbag strap with the carabiner, or wear it on the lanyard. For running, hiking and general outdoor sport, that carabiner clip is the feature doing the real work.
Merryking AI Language Translator: Who It's For
The Merryking translator is a genuinely different category of product. It is a set of open-wear earbuds with a 3-in-1 job: translation, music playback and phone calls. The headline number is 144 languages and accents with real-time two-way translation, and the brand is specific about how that splits. Eight key languages — Chinese, English, Japanese, Korean, Russian, German, French and Spanish — are free and work offline. The remaining 136 are available online, or offline through an in-app purchase. That distinction is the single most important thing to understand before buying, because it determines whether this device is useful to you on a plane with no Wi-Fi or only when you have a signal.
The modes are broader than plain conversation. Merryking lists free talk mode, offline mode, audio transcription and photo translation, which covers a few real situations: a face-to-face chat, a menu or sign you photograph, and a meeting or lecture you want transcribed. The brand also frames offline mode as a privacy feature, since nothing leaves the device, and says online translations use end-to-end encryption. That is a reasonable design argument for business users who do not want client conversations routed through a network.
Wear and battery are the other two things to weigh. The earbuds use an ergonomic ear-hanging design with soft silicone ear hooks, and the brand states the open-ear shape does not go inside the ear and is glasses-friendly — a real consideration if you wear frames all day. Battery is listed at up to 4 hours of listening time with a 10-meter Bluetooth range, and the charging compartment extends total use to 16 hours with fast charging that gives about an hour of use from 15 minutes plugged in. Comfortable for long sessions, but if you need all-day continuous audio, 4 hours per charge is the number to plan around.
Side-by-Side: Which Should You Choose?
• Best for protecting earbuds you already own → DAYJOY Soft Silicone Protective. It exists purely to shield an Oladance OWS Pro from scratches, drops and slips.
• Best for travel and business use → Merryking. Free talk mode, offline mode, audio transcription and photo translation map directly onto airports, meetings and menus.
• Best for outdoor sports and running → DAYJOY. The anti-lost carabiner clips to a handbag or backpack, and the silicone is anti-skidding by design.
• Best for long listening sessions → Merryking on comfort, with a caveat. The ear-hanging design with soft silicone hooks is built for extended wear, though listening time is listed at up to 4 hours per charge.
• Best for charging convenience → DAYJOY. The bottom cutout means you charge the earbuds without removing the cover.
• Best for privacy-conscious users → Merryking. Offline mode keeps built-in-language conversations on the device.
• Skip DAYJOY if → you own Oladance OWS 1 or OWS 2, since it is not compatible with those models, or you need water resistance.
These two products do not compete — they solve different problems, so my pick depends entirely on what you already have. If you own Oladance OWS Pro earbuds, I would buy the DAYJOY Soft Silicone Protective case: the charging cutout, the grippy soft silicone and the carabiner-and-lanyard bundle make it the more immediately useful purchase, and there is nothing else it needs to do. If you do not own OWS Pro earbuds and you want translation in your ears, the DAYJOY case is irrelevant to you. In my opinion, the Merryking AI Language Translator is the better buy for anyone whose actual goal is communicating across languages, especially with 8 languages working offline for free. Buy the one that matches the job. Check the current price on Amazon before you commit.
how to wear ows earbuds
Open-wear earbuds sit on the outside of your ear rather than inside the canal. The Merryking translator uses an ergonomic ear-hanging design with soft silicone ear hooks that rest over the ear and are described as glasses-friendly, while the DAYJOY case is a sleeve for the Oladance OWS Pro, which is worn the same open-ear way.
how to use ows earbuds
Use them like any Bluetooth earbud for music and calls, and use the companion app for the extra features. On the Merryking translator, that means choosing a mode — free talk, offline, audio transcription or photo translation — and picking your language pair. The 8 built-in languages work offline; the other 136 need a connection or an in-app purchase.
how to connect tws earbuds
Pairing is the standard Bluetooth process: put the earbuds in pairing mode, open your phone's Bluetooth settings and select the device. The Merryking translator is a true wireless set with a listed Bluetooth range of 10 meters, so keep your phone within that distance for a stable connection.
how to pair ows earbuds
Same routine as any TWS set — power them on, enter pairing mode, and confirm the device name in your phone's Bluetooth list. If a pair is already bonded to another phone nearby, disconnect that one first. Within a 10-meter range you should hold a steady link on the Merryking translator.
