How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want an open-ear design that keeps you aware of traffic, coworkers and announcements while you run or ride, choose Anker Soundcore V30i; if you need in-ear buds with a sealed fit, a battery meter you can actually read, and a translation app built in, choose Rulbovs Earbuds.
• Anker Soundcore V30i — biggest strength: Open-ear hooks that sit outside your ear canal, so nothing plugs you up and you stay aware of your surroundings. 12 hours per charge, 36 hours with the case, Bluetooth 5.3, app EQ control, IPX5.
• Anker Soundcore V30i — biggest trade-off: Open-ear means no noise isolation at all (the spec sheet lists noise control as "None"), so loud environments fight your music. It's also a renewed unit, not new stock.
• Rulbovs Earbuds — biggest strength: In-ear buds with dual 14.2mm drivers, ENC call noise reduction, Bluetooth 6.0, IP7 waterproofing, up to 60 hours total, and a built-in 164-language translation app with no subscription.
• Rulbovs Earbuds — biggest trade-off: The features are dense and the product identity is muddled — the listing itself mixes NE79 and NE70 model names, the warranty field says "no," and the translation/AI claims are the kind you want to verify in the app before relying on them.
• Pick Anker Soundcore V30i if you run, cycle, drive or work in an office and want your ears left open.
• Pick Rulbovs Earbuds if you want conventional sealed earbuds, long battery, loud call clarity, and translation as a bonus tool.
The V30i is a hook-style open-ear headphone — the driver sits outside your ear canal and fires sound toward it. The payoff is situational awareness. The listing calls this out directly: you can still hear transit announcements, oncoming cars and the people around you. If you've ever pulled an earbud out at a crosswalk or missed your stop because you were sealed off, that's the exact problem this design solves.
Under the hood it's a 14.2mm bio-material diaphragm driver, 20 Hz–20 kHz, 11 ohm impedance, Bluetooth 5.3, and an IPX5 rating with a nano-coating and sealed chamber over the chipset and battery. Battery life is 12 hours per charge, 36 hours with the case, and a 10-minute top-up gives you 3 hours — genuinely useful if you forget to charge before a commute. The soundcore app adds custom EQs, a volume boost and a reading mode.
Who should buy it: runners, cyclists, delivery and warehouse workers, drivers, and anyone in an open office who needs to hear a colleague say their name. Who should skip it: anyone who wants to disappear into music on a plane, train or noisy gym — with no noise control and an open design, you'll be turning the volume up and still hearing everything. Also skip it if you specifically want brand-new retail packaging, since this version is listed as renewed.
The Rulbovs Earbuds are a completely different animal: traditional in-ear buds that seal into your canal. That seal is why they can claim the bass and isolation the V30i can't. The sheet lists dual 14.2mm composite dynamic drivers with AAC/SBC support, adaptive noise cancellation, and ENC microphones that the listing says cut background noise by up to 90% on calls.
Battery is the headline number: 6–8 hours per charge and up to 60 hours with the case, recharged over USB-C in about 1.5 hours. There's a digital LED display on the case showing the remaining level of the case and each bud separately — a small thing that matters a lot when you're leaving the house. Bluetooth 6.0, a stated 15-meter range, and touch controls for play/pause, track skipping, volume, calls and voice assistant round it out. IP7 waterproofing is the highest rating of the two here and the most reassuring for sweaty workouts or rain.
The wildcard is translation: real-time two-way translation across 164 languages through a companion app, with the listing citing up to 98% accuracy and no subscription fees. It also mentions an AI assistant inside that app. Who should buy it: commuters, gym-goers, call-heavy workers, frequent travelers, and anyone curious about translation earbuds. Who should skip it: open-ear loyalists, and cautious buyers — the model naming is inconsistent (NE79 in the title, NE70 in the box contents), and the warranty field reads "no," so factor that in before committing.
Side-by-Side: Which Should You Choose?
• Best for staying aware of traffic and surroundings → Anker Soundcore V30i (open-ear by design, noise control listed as None).
• Best for loud, clear phone calls → Rulbovs Earbuds (ENC mics, dual drivers, sealed fit).
• Best for all-day comfort without ear fatigue → Anker Soundcore V30i (lightweight hooks, nothing inserted in the canal).
• Best for sweaty workouts and rain → Rulbovs Earbuds (IP7 vs IPX5), assuming the seal stays put.
• Best for bass you can feel → Rulbovs Earbuds — sealed in-ear delivery plus dual 14.2mm drivers is the physics-favored setup; the V30i's 14.2mm driver is tuned for balance, not thump.
• Best for tuning your own sound → Anker Soundcore V30i via the soundcore app's EQ, volume boost and reading mode.
• Best for travel and language barriers → Rulbovs Earbuds with its 164-language translation app and no subscription requirement.
In my opinion, the right pick here depends entirely on one question: do you want your ears open or sealed? If you run, ride, drive or work around people, I'd buy the Anker Soundcore V30i — the hook design, 12-hour single-charge battery, app EQ and IPX5 rating are a coherent, well-defined package from a brand that's been doing audio for years. If you want classic in-ear buds with big battery, strong call handling and a translation tool built in, I'd buy the Rulbovs Earbuds, while accepting that the feature list is ambitious and the documentation is messier. My personal pick for most people is the V30i, purely because it does one thing clearly and well.
Both can work, but they're built differently for it. The V30i's hooks keep you aware of cars and people, which I'd want on roads. The Rulbovs' IP7 rating and sealed fit suit treadmill or gym work where awareness matters less.
That's what the listing states, and it says there are no subscription fees — you download the app and pair the buds. Treat it as a bonus feature rather than the main reason to buy, and confirm the language list in the app before you depend on it abroad.
The Rulbovs Earbuds. They list adaptive noise cancellation plus ENC call noise reduction, and the in-ear seal blocks sound passively too. The Anker Soundcore V30i lists noise control as None — that's the deliberate trade-off for open-ear awareness.
It means you're getting refurbished rather than new retail stock. The listing backs it with an 18-month warranty, so the coverage is there. If sealed retail packaging matters to you, that's the one reason to look elsewhere. As for cost, check the current price on Amazon using the button on this page before deciding.
