If you want open-ear-style awareness is not essential and you want Bluetooth 5.3, up to four hours of playback, and waterproof construction for work, choose VIVIDUS Air 31; if you need newer Bluetooth 5.4, a dual-microphone noise-cancelling call system, and a case display that reports charge for both the case and earbuds, choose Vvikizy LED Display Noise.
For desk tasks, commuting, and calls, the deciding difference is less about the display and more about battery details, fit, and call-focused features.
Neither is actually an open-ear or bone-conduction design: both are in-ear earbuds.
• VIVIDUS Air 31’s strength: Up to four hours of continuous playback, Bluetooth 5.3 with a stated range of up to 33 feet, and waterproof construction. Trade-off: Its listed playback time is four hours, and its noise control is passive isolation rather than active noise cancellation.
• Vvikizy LED Display Noise’s strength: Bluetooth 5.4, dual microphones with noise-cancellation technology for calls, and a case screen showing charge for the case and earbuds. Trade-off: It lists up to three hours of playback per charge, one hour less than the VIVIDUS.
• VIVIDUS fits people who want in-ear earbuds for work and exercise, with a longer stated single-charge playback window and a waterproof design.
• Vvikizy fits people who put call-focused noise filtering, battery visibility, and a purple color option ahead of the extra hour of listed playback.
The VIVIDUS Air 31 is a straightforward choice for someone who wants true wireless in-ear earbuds that can move between work and active use. Bluetooth 5.3 is listed with a wireless range of up to 33 feet, which gives you some room to move away from a paired device without immediately leaving its stated connection range. The earbuds also include touch controls and a built-in microphone for managing playback and hands-free calls.
Its battery advantage is specific and useful: the listed continuous playback time is up to four hours, with a stated charging time of 1.5 hours. The LED on the case shows battery status, so you can check power without guessing. For a workday made up of shorter meetings, listening sessions, and breaks, that combination makes charging status and playback capacity easy to compare. The case is listed at 3.5 by 2.5 by 1.5 inches, a detail worth considering if you want to carry it in a small bag or pocket.
How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
Updated: 2026-10-20 · 8 min read · Independent comparison
Skip it if your main priority is a stated dual-microphone noise-cancelling call system: the VIVIDUS sheet lists a built-in microphone and passive noise isolation, not that dual-microphone feature.
Vvikizy LED Display Noise is the more call-oriented pick on paper. Its feature list describes a dual-microphone system with noise-cancellation technology intended to filter ambient sound during calls. That makes it a natural candidate for someone who often takes calls in a gym, during a commute, or in another busy environment. The product also lists one-touch controls for music and calls, along with voice-assistant activation.
Bluetooth 5.4 is the newer version specified in this comparison, and the listed wireless range is up to 15 meters. The charging case’s LED screen reports battery status for both the case and the earbuds, which gives a more detailed view than a display that only indicates general case power. The listed single-charge playback or talk time is up to three hours, and a full recharge is stated to take 1.5 hours. The case is described as having a 230 mAh battery, though the sheet does not state a total combined playback time with the case.
The earbuds are listed as in-ear, purple, and 4.8 grams each. Their design is described as a lightweight clamp-on fit intended to stay secure during running and workouts. The total weight is given as 40.4 g. Those details may appeal to someone who wants a secure-feeling option for movement and prefers purple over the VIVIDUS’s listed black title color, though the product information also contains conflicting color fields for VIVIDUS.
Skip it if you want the longer stated playback time per charge: Vvikizy lists up to three hours, compared with up to four for VIVIDUS Air 31.
• Best for longer stated playback on one charge → VIVIDUS Air 31. Its listed maximum is up to four hours; Vvikizy lists up to three.
• Best for a call-focused microphone setup → Vvikizy LED Display Noise. It specifically lists dual microphones and noise-cancellation technology for calls.
• Best for a stated waterproof design → VIVIDUS Air 31. Its product details call the construction waterproof, making it the more suitable fit on paper for sweat or light rain.
• Best for newer Bluetooth specification → Vvikizy LED Display Noise. It lists Bluetooth 5.4, while VIVIDUS lists Bluetooth 5.3.
• Best for checking separate case and earbud battery status → Vvikizy LED Display Noise. Its display is described as showing charge for both.
• Best for a specified connection distance → VIVIDUS Air 31. Its stated range is up to 33 feet; Vvikizy’s is up to 15 meters.
• Best for video or gaming latency details → VIVIDUS Air 31. It lists 40 ms audio latency, a useful specification to compare if lip-sync timing matters to you.
• Best for secure-fit exercise details → Vvikizy LED Display Noise. Its listing describes a clamp-on fit designed to stay put during running and workouts.
First, decide whether your work use is mainly listening or talking. VIVIDUS offers the longer stated playback window, while Vvikizy gives a more specific call-focused feature set with dual microphones and noise-cancellation technology. That is a meaningful distinction for someone who spends long stretches in calls, but it does not establish how either model will sound in a particular room. The product details are specifications, not a guarantee of call quality in every setting.
Next, think about how much isolation you want. Both products are in-ear, so neither should be treated as an open-ear pair that leaves the ear canal unobstructed. VIVIDUS explicitly lists passive noise isolation. Vvikizy describes noise cancellation in connection with its microphones and calls, but the available information does not clearly establish active noise cancellation for listening to music. If hearing nearby coworkers is important, neither product’s listed features are a substitute for an open-ear design.
Battery claims also need a careful read. VIVIDUS states up to four hours of continuous playback and a 1.5-hour charge time. Vvikizy states up to three hours of music playback or talk time per charge and the same 1.5-hour recharge time. Vvikizy’s 230 mAh case battery is specified, but no combined playback figure is provided. I would compare the single-charge figures first rather than assume how many extra hours the case will add.
Finally, make sure the physical fit and controls suit your routine. Both models use touch or one-touch controls, which can be handy when your phone is put away, but the sheets do not spell out every control gesture. VIVIDUS gives a case size, while Vvikizy gives individual earbud and total weights and describes a clamp-on fit. Those are different kinds of fit information, not a direct comfort comparison. If the current price matters to your decision, check the current price on Amazon; I can’t determine value without relying on current pricing.
For work, I would choose VIVIDUS Air 31 if I wanted the longer stated playback time, a clearly specified waterproof design, and a listed 40 ms latency figure for video or gaming.
I would choose Vvikizy instead if my workday depended more on calls in noisy surroundings and I valued its dual-microphone call feature and separate case-and-earbud battery display.
Neither is the pick for someone specifically searching for open ear earbuds for work or the best bone conduction headphones for work; both are in-ear models.
My preference is VIVIDUS for a more versatile mix of work listening and active use, while Vvikizy has the more clearly described call-focused feature set.
Vvikizy lists a dual-microphone system with noise-cancellation technology for calls, giving it the more explicitly call-focused feature set. VIVIDUS lists a built-in microphone and hands-free calling, but not a dual-microphone system.
VIVIDUS lists passive noise isolation. Vvikizy describes noise cancellation in its dual-microphone call feature, but its product details do not clearly confirm active noise cancellation for listening to music.
VIVIDUS lists up to four hours of continuous playback per charge. Vvikizy lists up to three hours of music playback or talk time per charge; both list a 1.5-hour recharge time.
No. Both are described as in-ear earbuds. Someone who specifically needs an open-ear or bone-conduction design should compare products built around that fit rather than assume either of these leaves the ear open.
