How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a pair of earbuds that translates speech on the fly and doubles as a normal Bluetooth headset, choose Vikye B28; if you need a compact, water-resistant carry case that keeps a set of JBL Endurance Peak earbuds and their charging cable organized and protected, choose Alltravel TWS Earbuds Case. These two listings look like they belong in the same search results, but they solve completely different problems — one is a piece of electronics, the other is a piece of luggage. That mismatch is exactly why this comparison is worth reading before you buy the wrong thing.
• Vikye B28 — biggest strength: it is an actual working device. Bluetooth 5.0 audio plus four translation modes, coverage of 74 languages and 70 accents, and a claimed 97% translation accuracy across four translation engines.
• Vikye B28 — biggest trade-off: battery life is modest for a gadget this ambitious — 4 hours of continuous use per charge and up to 120 hours of standby, so heavy travel days will need charging breaks.
• Alltravel TWS Earbuds Case — biggest strength: purpose-built protection. A semi-hard PEVA shell with a matching-size base, an elastic strap for the device and a mesh pocket for the cable, plus a carabiner for clipping it to a bag.
• Alltravel TWS Earbuds Case — biggest trade-off: it contains no electronics at all. It is a case only, made specifically for JBL Endurance Peak 3, Peak 2 and Peak True Wireless models, so it is useless if you own anything else.
• Who Vikye B28 is for: travelers, language learners and anyone who talks to people across a language barrier.
• Who Alltravel TWS Earbuds Case is for: JBL Endurance Peak owners who want their earbuds and cable protected in one tidy, pocketable bundle.
The Vikye B28 is a translator first and an earbud second. The headline spec is language coverage: 74 languages and 70 accents, which the listing frames as reaching more than 90% of the world's population. Behind that sits a stack of four translation engines and a network of 15 servers, which the brand says delivers roughly 0.5-second latency and about 97% accuracy. Those are manufacturer figures, not something I can verify here, but the architecture they describe — multiple engines plus distributed servers — is the sensible way to build this kind of tool.
What I like more than the raw numbers is the mode structure. You get touch mode, external mode, speak mode and offline mode. In practice that means you can pick the interaction style that suits the situation: handing a bud over or passing a phone around for a face-to-face exchange, speaking into it yourself, or falling back on offline mode when you have no reliable data connection. Offline support is the detail that makes this genuinely useful on a trip rather than just at a desk.
It is also a normal Bluetooth 5.0 headset. There are speakers built in, so it works for music and phone calls, and the listing mentions a digital display on the charging case. The earbuds themselves are described as ergonomic and compact, and the weight is listed at 2.89 ounces for the package. Battery is the honest weak point: 40mAh in each bud plus a 350mAh charging compartment, quoted as 4 hours of continuous work and 120 hours of standby. Four hours is a session, not a day.
Buy it if you regularly need to communicate across languages — business travel, study, hosting visitors, or family conversations — and you want one gadget that also plays music and takes calls. Skip it if you just want cheap everyday earbuds for the gym, or if you need all-day battery without topping up.
Now the other half of this comparison, and it is a completely different product category. The Alltravel TWS Earbuds Case is a protective shell for JBL Endurance Peak 3, Peak 2 and Peak True Wireless earbuds. That compatibility list is the whole story: if you do not own one of those models, this case has no job to do. It is not a universal pouch and it is not sized to fit the Vikye B28.
Where it earns its place is organization. You get a palm-sized compact case with a base molded to match the device, an elastic strap that holds the charging case down, and a mesh pocket for the charging cord and small accessories. That last part matters more than it sounds — throwing a cable loose into a bag is how you end up with scratched plastic and a tangled mess, and the mesh pocket solves that directly.
Buy it if you own JBL Endurance Peak 3, Peak 2 or Peak True earbuds and you want them, plus the cable, kept together and protected. Skip it if you own any other earbuds, or if you were hoping this listing included a device.
Side-by-Side: Which Should You Choose?
• Best for actual audio and calls → Vikye B28. It is a Bluetooth 5.0 headset with built-in speakers; the Alltravel case makes no sound at all.
• Best for language translation → Vikye B28. Four modes, 74 languages and 70 accents, four translation engines and an offline option. Nothing in the Alltravel listing competes here.
• Best for protecting JBL Endurance Peak earbuds → Alltravel TWS Earbuds Case. Molded fit, elastic strap, mesh cable pocket, semi-hard water-resistant PEVA shell.
• Best for travel organization → Alltravel TWS Earbuds Case. Palm-sized, 1.8 ounces, with a carabiner to clip onto a bag.
• Best for long sessions away from a charger → neither, honestly. Vikye B28 runs about 4 hours per charge; the Alltravel case has no battery because it has no electronics. If runtime is your priority, keep looking.
• Best for everyday carry weight → Alltravel TWS Earbuds Case. At 1.8 ounces it is lighter than the 2.89-ounce Vikye package.
• Best for a gift with obvious utility → depends on the recipient. Vikye B28 suits a traveler or language learner; Alltravel suits someone who already owns JBL Endurance Peak earbuds.
• Best if you own non-JBL earbuds → Vikye B28. The Alltravel case fits only the three listed JBL models.
My Verdict
what is tws earbuds
TWS stands for "true wireless stereo" — earbuds that connect to each other and your phone over Bluetooth with no wire between them. The "TWS Earbuds Case" in the Alltravel name refers to a carry case for that type of earbud, not to the earbuds themselves.

It means the two earbuds are fully independent and wireless, syncing to each other rather than joined by a cable. In this comparison, the Vikye B28 is the actual TWS device; the Alltravel product is only the protective case for one.
how to tws earbuds
Pair them by turning on Bluetooth on your phone and connecting to the earbud from the device list. The Vikye B28 pairs as a Bluetooth 5.0 headset, and you then pick one of its four modes — touch, external, speak or offline — depending on whether you want translation or ordinary audio.
