If you want a lighter, simpler set of earbuds with a bigger driver and a familiar auto-reconnect routine, choose SGNICS Sonim XP5plus; if you need a charging case with a visible power display, more total playback and a power-bank-style battery, choose VOLT PLUS TECH PRO. Both are budget-friendly Bluetooth 5.3 earbuds with touch controls and an IPX4-type water-resistance claim, so the real decision comes down to how you use them: short daily sessions versus long days away from a wall outlet.
• SGNICS Sonim XP5plus — biggest strength: the 13mm compound diaphragm dynamic driver, which the data sheet says is tuned to make music sound fuller and more detailed, plus a genuinely light 3.8g in-ear build.
• SGNICS Sonim XP5plus — biggest trade-off: battery life is rated at 7 hours per charge and 31 hours total with the case, which is solid but not class-leading, and it leaves out extras like a digital power display or active noise cancellation.
• VOLT PLUS TECH PRO — biggest strength: the 2,000mAh recharge case with an LED screen that shows the exact power level of both the case and the earbuds, backed by a 36-hour total playback figure.
• VOLT PLUS TECH PRO — biggest trade-off: the spec sheet is messier — it lists both IPX4 and IPX3 waterproofing, and it carries noticeably more weight at 4 ounces for the whole package.
• Who each pick is for: the SGNICS is for listeners who want a light, no-fuss daily earbud with a large driver; the VOLT PLUS TECH PRO is for people who want to see their battery level and stretch playback across a long trip, gym week or work stretch.
The SGNICS Sonim XP5plus is built around one clear idea: put a large 13mm compound diaphragm dynamic speaker in each bud, then keep the whole thing light. At 3.8g per earbud with an in-ear fit, these are designed to disappear in your ears during a commute, a walk or a couple of hours at a desk. The data sheet describes the sound as "full and rich in details," which is the kind of language you'd expect from a bigger driver — and 13mm is genuinely large for this category, where many rivals run smaller drivers.
Battery is rated at 7 hours per single charge, with the case able to top the buds up roughly three to four times for a total of 31 hours when both earbuds are in use. That's a comfortable rhythm for most people: charge the case once or twice a week, wear the buds for a workday, drop them back in. The Bluetooth 5.3 chip is pitched as lower-power and more stable, with a stated range of about 12 meters, which covers the usual "phone on the counter, buds in the next room" scenario.
VOLT PLUS TECH PRO: Who It's For
The VOLT PLUS TECH PRO takes the opposite approach: it leans hard into battery and information. The headline item is a 2,000mAh recharge case that the data sheet says delivers up to 8 charges and a total of 36 hours of playback, with each earbud streaming beyond 5 hours per charge. Whether you're on a long flight, a weekend camping trip or just chronically bad at remembering to charge things, the point is that you're carrying a small power reserve in your pocket.
The feature I find most practical is the LED screen. It shows the power level of both the charging case and the earbuds, so you never have to guess whether you're at 80% or 8%. That single display changes how you use earbuds day to day — you can plan a charge instead of discovering an empty battery mid-call. The case also does double duty as a portable storage box, and the package includes two sizes of ear tips (small and large), a USB-C charging cable and a user manual.
On audio and calls, the sheet lists Bluetooth 5.3 with CVC 8.0 intelligent noise reduction, claimed to cut noise by up to 25 dB, plus an "8D stereo surround" tuning and a frequency response figure that runs very high on paper. The design uses an in-ear separation layout so you can run one bud or both, and the touch controls cover track skipping, volume and wake-up. One thing to watch: the listing text is inconsistent on water resistance, describing IPX4 in the title and IPX3 nano-coating in the description, and it explicitly warns that the charging box itself is not waterproof. Buy the VOLT PLUS TECH PRO if battery anxiety is your main problem and you want to see your power level at a glance. Skip it if you want the lightest possible bud or you need a case you can get wet.
• Best for sound detail from a big driver → SGNICS Sonim XP5plus. The 13mm compound diaphragm driver is the larger, more deliberate audio spec of the two.
• Best for total battery life → VOLT PLUS TECH PRO. 36 hours total versus 31 hours, plus a 2,000mAh case that the sheet says can recharge the buds up to 8 times.
• Best for knowing your battery level → VOLT PLUS TECH PRO. The LED display shows the charge of both the case and the earbuds; the SGNICS has no equivalent readout in its data.
• Best for lightweight wear → SGNICS Sonim XP5plus. 3.8g per earbud is a genuinely light figure, and the overall package is far lighter than the 4-ounce VOLT PLUS TECH PRO kit.
• Best for call clarity in noisy places → VOLT PLUS TECH PRO on paper. It lists CVC 8.0 noise reduction with a stated reduction of up to 25 dB; the SGNICS lists ENC for its mic but no comparable figure.
• Best for a simple, familiar routine → SGNICS Sonim XP5plus. Open the case, auto-reconnect, touch to control — minimal setup, minimal fiddling.
• Best for gym and outdoor sweat → either, with a caveat. Both claim IPX4-level protection, but the VOLT PLUS TECH PRO sheet also mentions IPX3 and warns the case isn't waterproof, so keep the box dry.
• Best for travel and long days away from power → VOLT PLUS TECH PRO. The power-bank-style case is built for exactly that.
In my opinion, the VOLT PLUS TECH PRO is the better buy for most people, because the two things that actually ruin a day with cheap earbuds are dead batteries and not knowing how much charge is left — and this model solves both with a 36-hour total figure and an LED display that shows the exact level. I'd pick it for travel, long workdays and anyone who hates guessing. That said, if you value a lighter bud and a bigger 13mm driver over raw battery, the SGNICS Sonim XP5plus is the smarter pick and the simpler one to live with. Check the current price on Amazon before you decide — both sit in the budget tier, but the gap between them can swing your choice.
Yes, based on the specs. The VOLT PLUS TECH PRO lists 36 hours of total playback with a 2,000mAh case, while the SGNICS lists 31 hours total with 7 hours per single charge. The difference is modest, but the LED display on the VOLT PLUS TECH PRO makes that battery easier to manage.
The SGNICS Sonim XP5plus lists a 13mm compound diaphragm dynamic driver, which is a large driver for this price bracket and is described as producing fuller, more detailed sound. The VOLT PLUS TECH PRO leans on "8D stereo surround" and CVC 8.0 tuning instead. Without listening tests I can't declare a winner, but on paper the SGNICS has the more concrete audio hardware claim.
Both claim IPX4-level water resistance, which covers sweat and light rain. Be careful with the VOLT PLUS TECH PRO, though: its own description also mentions IPX3 and states the charging case is not waterproof. Wipe both sets dry before they go back in the case.
Both use standard Bluetooth 5.3, so they pair with Android and iOS devices, including the Galaxy A35 that the VOLT PLUS TECH PRO listing names. The SGNICS supports Siri wake-up, and both reconnect automatically to the last paired device once you've paired them the first time.
