How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want real-time AI translation in an open-ear design you can wear all day while staying aware of your surroundings, choose ERAZERL AI Translation Earbuds; if you need translation plus a phone-free control screen and a built-in finder for misplaced buds, choose MINISO MS109.
• ERAZERL AI Translation Earbuds biggest strength: a true open-ear (OWS) fit with pressure-free comfort, Bluetooth 6.0, ANC, and 135-language real-time translation at under 0.5 seconds delay — built for all-day wear while you stay aware of traffic, announcements, and conversations around you.
• ERAZERL AI Translation Earbuds biggest trade-off: setup is a two-step process — pair the headset to your phone first, then connect it to the companion app — and there's no on-board screen, so every control runs through touch gestures or your phone.
• MINISO MS109 biggest strength: an LCD touchscreen on the charging case puts 15+ functions (music, EQ, voice commands, alarm, stopwatch, remote camera) at your fingertips without touching your phone, plus a "Find My Earbuds" tracker for misplaced buds.
• MINISO MS109 biggest trade-off: it's an in-ear design, not open-ear — so while it seals in sound and blocks noise, it also seals you off from your surroundings, and translation requires downloading the Auralntelli app.
• Who each pick is for: ERAZERL for open-ear comfort and ambient awareness during travel and long wear; MINISO for users who want screen-based control and a lost-earbud safety net.
The ERAZERL AI Translation Earbuds are a 3-in-1 package: real-time AI translation, clear phone calls, and high-fidelity music. Translation covers 135 languages — Spanish, Chinese, English, Japanese, Korean, German, French, and more — with a delay under 0.5 seconds and accuracy up to 98%, and it works with both iOS and Android. There's also an integrated AI assistant that answers questions on demand. The standout spec, though, is the design: the NE20 is an open-ear (OWS) earbud, meaning it rests outside your ear canal instead of plugging it.
That open-ear shape is the whole point of this model, and it's what I'd build my buying decision around. Pressure-free open-ear buds are made for extended wear — flights, long workdays, walking tours, conference halls — because nothing is jammed into your ear canal. More importantly, you keep your ambient awareness. You can hear a gate announcement, a barista calling your name, or traffic behind you while translation or music keeps running. The spec sheet backs this up with Active Noise Cancellation, Bluetooth 6.0 with a 10-meter wireless range, a 1.5-hour charge time, and up to 50 hours of average battery life.
Buy the ERAZERL if you want one pair that handles travel, business meetings, language learning, and everyday listening without ever blocking your ears. The multi-scenario modes cover a lot of ground: hands-free real-time communication, dual-ear click control, live photo translation via camera, AI conversation mode, conference mode for multilingual meetings, a dual mode that runs music and translation in parallel, and voice memos with automatic transcription.
MINISO MS109: Who It's For
The MINISO MS109 is a 4-in-1 translator earbud: real-time translation, video calls, phone calls, and high-fidelity music. Translation lands at the same headline numbers as the ERAZERL — 135 languages, under 0.5 seconds delay, up to 98% accuracy, iPhone and Android compatible — with the same AI assistant answering questions after you ask. It also shares the same seven translation modes: hands-free, dual-ear control, live photo translation, AI conversation, conference mode, dual mode, and voice memos.
Where the MS109 separates itself is control. An intuitive LCD touchscreen on the case gives you 15+ functions without reaching for your phone: music playback, EQ settings, voice commands, and handy tools like an alarm, stopwatch, and remote camera shutter. That's a genuinely different way to live with a pair of earbuds — you can adjust EQ or fire off a voice command straight from the case. It also packs "Find My Earbuds," which shows the last known location through the companion app and triggers an audible alert so you can pinpoint a stray bud at home, at work, or outdoors. Battery is a 1.5-hour charge for up to 50 hours of average life, same as the ERAZERL.
The trade-off is the fit. The MS109 is an in-ear design, not open-ear. That means a seal in your ear canal, which is great for isolation and immersive listening in noisy places, but it also means you're cut off from what's happening around you — the opposite of the open-ear experience. If you've ever wanted earbuds that disappear into your ears and let you tune the world out, that's a feature. If you need to hear your surroundings, it's a limitation.
Buy the MS109 if you want screen-driven control, a lost-earbud tracker, and in-ear noise isolation. Skip it if ambient awareness is your priority or you dislike anything sitting inside your ear canal. One setup note: translation features require downloading the free Auralntelli app, and no subscription is needed.
Side-by-Side: Which Should You Choose?
• Best for staying aware of your surroundings → ERAZERL AI Translation Earbuds. Nothing blocks your ear canal, so announcements, traffic, and conversations come through.
• Best for phone-free control → MINISO MS109. The LCD touchscreen handles 15+ functions, including EQ and voice commands, without your phone.
• Best for never losing a bud → MINISO MS109. Find My Earbuds shows the last known location and plays an audible alert.
• Best for noise isolation and immersive listening → MINISO MS109. The in-ear seal plus ANC is built for tuning out busy environments.
• Best for translation reach → a tie. Both cover 135 languages, under 0.5 seconds delay, and up to 98% accuracy across the same seven modes.
• Best for battery life → a tie. Both charge in 1.5 hours and average 50 hours of life.
• Best for business and conference use → ERAZERL AI Translation Earbuds. Conference mode pairs with an open-ear fit that lets you hear the room while translating.
I'd buy the ERAZERL AI Translation Earbuds. The OWS open-ear design is the reason: it's the one spec that changes how you actually live with these things day to day, and it's the only one of the two that gives you translation without cutting you off from the world. The 135-language coverage, sub-0.5-second delay, Bluetooth 6.0, ANC, and 50-hour battery make it a complete travel and business companion. The MS109 is the better pick if you want a screen on the case and a finder for lost buds — but in my opinion, comfort and awareness win. Check the current price on Amazon before you decide.
how to wear ows earbuds
Open-ear (OWS) earbuds like the ERAZERL rest outside your ear canal rather than inside it, usually hooking over or around the ear so the driver sits near — not in — the opening. The pressure-free fit is designed for extended wear without discomfort. Position them so you hear both your audio and your surroundings.
how to connect tws earbuds
For the ERAZERL, the brand's own note gives the order: connect the headset to your phone first, then connect it to the app on your phone. Both models here use Bluetooth, and the ERAZERL spec lists Bluetooth 6.0 with a 10-meter range. The MS109 requires the free Auralntelli app for translation features.
how to pair ows earbuds
Pairing follows the same Bluetooth steps as any wireless earbud: put the buds in pairing mode, then select them from your phone's Bluetooth list. The ERAZERL adds a second step — after the phone connection, link the headset to its companion app so translation and the AI assistant work. Do the phone pairing first.

Once paired, you control the ERAZERL by touch — there's no screen, so gestures handle playback, calls, and mode switching. Translation runs through the app across seven modes, including hands-free, photo translation, conference mode, and voice memos. The MS109 does the same modes but lets you manage many functions from its LCD touchscreen instead.
