If you want a feature-packed pair with a smart LED power display, a case that doubles as a power bank, and proper active noise cancellation, choose VOLT PLUS TECH Pro Earbuds; if you need a lightweight, simple everyday set with a large-capacity case that can top up your phone, choose Tomantery Earbuds.
• VOLT PLUS TECH Pro Earbuds — biggest strength: A genuinely loaded spec sheet: Bluetooth 5.3, quad microphones with CVC 8.1 noise reduction, IPX4 water resistance, 8D bass, and a 2,000 mAh case that can recharge the buds or act as a power bank.
• VOLT PLUS TECH Pro Earbuds — biggest trade-off: More to manage. Touch controls with volume and track switching, a digital display, and a separate power-bank function mean a busier learning curve than a plain pair of buds.
• Tomantery Earbuds — biggest strength: A clean, no-fuss design with an LED display you can read without opening the lid, a composite diaphragm for crisp highs, and a 1,200 mAh case that can also charge your phone.
• Tomantery Earbuds — biggest trade-off: Fewer headline features. Its noise control is passive isolation only, and the spec sheet doesn't list active noise cancellation or a stated IP water-resistance rating.
• Who each pick is for: Choose VOLT PLUS TECH for calls, workouts, gaming and travel where noise reduction and battery flexibility matter. Choose Tomantery for straightforward music, running and everyday listening where simplicity wins.
The VOLT PLUS TECH Pro Earbuds are built for people who want their earbuds to do more than play music. The headline spec is Bluetooth 5.3, the newer generation of the wireless standard, which tends to mean steadier pairing and better efficiency than older chips. Around that sit four microphones — two per earbud — paired with CVC 8.1 noise reduction, which the spec sheet says cuts noise by up to 30 dB. In practice that matters most on calls: the person on the other end hears less of the street, the gym or the train.
The case is where this pair really separates itself. It packs a 2,000 mAh battery and can recharge the buds for up to 36 hours, or work as a power bank for your phone. A digital LED display shows the exact power level of both the case and the buds, so you're never guessing. The buds themselves stream for over five hours, with the case pushing total listening toward the 25-hour mark. Audio latency is listed at just 9 milliseconds, which is a strong number for gaming and video, where lag is the thing that ruins the experience.
On the fit and durability side, you get three tip sizes (S, M, L), an in-ear design with 26 mm dynamic drivers, IPX4 water and sweat resistance, and 8D stereo surround sound. Touch controls handle track skipping and volume. There's a one-year manufacturer's limited warranty too.
Who should skip it? If you want the absolute simplest possible earbud — pair, play, done — the extra features and touch gestures may feel like more than you need. And note the listing states the charging case itself is not waterproof, so don't leave it out in the rain.
The Tomantery Earbuds take a different approach: keep it simple, keep it comfortable, and make the case useful. The build is ABS plastic, and the in-ear shape is aimed squarely at all-day wear. The spec sheet calls out comfort directly, which tells you the design priority here — something you can leave in through a run, a commute or a work session without thinking about it.
Sound is handled by a dynamic driver with a composite diaphragm. That's the part that shapes the highs: a lighter, faster-moving diaphragm tends to reproduce high frequencies with more detail, so vocals and cymbals come through cleanly rather than muddy. For calls, a dual-core microphone is designed to hold up in noisy environments, so game chat and voice calls stay intelligible.
The case is the standout. It carries a 1,200 mAh battery and, like the VOLT PLUS TECH, can charge your phone as well as the buds — a genuinely handy trick when your handset is dying and there's no outlet in sight. The LED display lets you check remaining power without opening the lid, and the buds themselves run on 50 mAh batteries each. Bluetooth range is listed at roughly 10 meters (about 32.8 feet).
Side-by-Side: Which Should You Choose?
• Best for battery flexibility → VOLT PLUS TECH Pro Earbuds. Its 2,000 mAh case offers up to 36 hours of recharging and doubles as a power bank.
• Best for calls in noise → VOLT PLUS TECH Pro Earbuds. Quad mics plus CVC 8.1 noise reduction rated to cut noise by up to 30 dB.
• Best for gaming and video → VOLT PLUS TECH Pro Earbuds. A listed 9 ms latency keeps audio and picture in sync.
• Best for workouts and rain → VOLT PLUS TECH Pro Earbuds. IPX4 water and sweat resistance covers gym sessions and wet weather.
• Best for comfort-first everyday wear → Tomantery Earbuds. The in-ear design is explicitly built around a comfortable fit for long sessions.
• Best for detailed highs → Tomantery Earbuds. The composite diaphragm is tuned to bring out richer high-frequency detail.
• Best for a no-fuss setup → Tomantery Earbuds. Fewer features means less to learn and less to fiddle with.
• Best for topping up your phone → Tomantery Earbuds. Its 1,200 mAh case charges your handset as well as the buds.
My Verdict
Yes. They use four microphones with CVC 8.1 noise reduction, which the spec sheet rates to reduce noise by up to 30 dB. That's designed to keep your voice clear in busy or windy places.
They have passive noise cancellation, which relies on the in-ear seal to block outside sound. There's no active noise cancellation listed, so don't expect electronic noise blocking.
The VOLT PLUS TECH case holds 2,000 mAh and can recharge the buds for up to 36 hours, with total listening around 25 hours. The Tomantery case is 1,200 mAh with 50 mAh per bud, so it trails on raw capacity.
Yes — both cases can act as a power bank. The VOLT PLUS TECH case is the larger of the two at 2,000 mAh, while the Tomantery case is 1,200 mAh.
