• Kelazola's biggest strength: CVC8.0 dual-mic noise cancelling paired with a 500mAh battery rated for 110 hours of play time, 100 hours of talking and 90 days of standby — the longest endurance figure in this comparison by a wide margin.
• Kelazola's biggest trade-off: It's a plastic hook-style earpiece with passive noise cancellation only, and it charges over about 3 hours with no charging case in the box.
• New Bee's biggest strength: A 500mAh charging case that tops the earpiece up on the go, plus Type-C direct charging as a backup — so a dead case never strands you.
• New Bee's biggest trade-off: Shorter endurance per charge and per case cycle (72 hours of total talk time), and its 15g body weight is listed at 5 g in the item details, so the fit feel is a genuinely different animal from Kelazola's hook design.
• Who each pick is for: Kelazola for long-shift talkers who want one charge to last days; New Bee for people who move around and want a pocketable power bank built into the product.
Kelazola's whole pitch is call endurance. The 500mAh battery is rated for 110 hours of play time, 100 hours of talking and 90 days of standby, with a roughly 3-hour recharge. If you take calls all day — dispatch, remote work, long drives — that's the number that matters, because it means you're charging on a weekly rhythm rather than a daily one.
The audio side leans on CVC8.0 noise cancelling with two built-in HD microphones, a proprietary DSP layer and high-quality speakers. In practice that combination is aimed at the person taking calls from a loud place: a busy street, a warehouse floor, the cab of a truck. Kelazola also supports pairing two Bluetooth devices at once, so a call coming into either your phone or your laptop gets picked up on the same earpiece. Range is listed at 33 feet / 10 meters.
Who should buy it: heavy call users who want the longest possible time between charges, like the dual-device pairing, and prefer a physical mute button they can find by feel.
Who should skip it: anyone who wants a charging case, active noise cancellation, or a lighter, less hook-heavy fit. Kelazola uses passive noise cancellation, and there's no case in the box — just the cable, eartips and manual.
New Bee Headset V5.1: Who It's For
New Bee solves a different problem: running out of power away from a wall. The earpiece comes with a 500mAh charging case, and total talk time is rated at 72 hours. A full Type-C charge takes about 1.5 hours, and there's an LED power display so you can see the battery level without guessing. The clever part is the two charging paths — drop the earpiece in the case, or plug the Type-C cable straight into the earpiece if the case itself is flat. That redundancy is the single most practical thing about this headset.
The mic setup is dual-microphone with a lengthened main mic boom, which is designed to keep your voice focused during calls. New Bee's materials also list Active Noise Cancellation rather than passive, plus ENC noise cancellation in the feature set, and the driver is a 13mm dynamic unit with 32 ohm impedance and a stated 40ms audio latency. That latency figure matters if you're using it for anything beyond voice — it's low enough to keep audio and video reasonably in step.
Fit-wise, New Bee gives you a 270° rotating mic boom and a 180° swiveling ear hook, so it works on either ear, and S/M/L ear tips let you dial in the seal. The design is blue with a black case, plastic and silicone construction, and the item weight is listed at just 5 g. It pairs with two devices at once over Qualcomm's QCC3020 Bluetooth 5.1 chip, with a 15-meter range, and plays nicely with iOS, Android, PC and laptops.
Who should buy it: drivers, warehouse and shift workers, and anyone who wants a pocketable case, a visible battery readout and a second way to charge.
Who should skip it: people who need the absolute longest single-charge runtime, or who dislike in-ear tips and prefer a hook that sits further off the ear canal. Also note the Type-C cable ships without an AC adapter.
Side-by-Side: Which Should You Choose?
• Best for charging convenience → New Bee Headset V5.1. The 500mAh case plus direct Type-C charging means two ways to stay powered, and a 1.5-hour top-up.
• Best for noise handling on paper → New Bee Headset V5.1. It lists Active Noise Cancellation and ENC, while Kelazola relies on passive noise cancellation plus CVC8.0 mic processing.
• Best for heavy all-day talkers → Kelazola Headset V5.1. Fewer charging interruptions across a long week.
• Best for on-the-go and driving use → New Bee Headset V5.1. Pocketable case, LED battery display, lightweight build and a 270° boom.
• Best for fit customization → a tie, with a caveat. Kelazola gives six earplugs in three sizes plus a rotatable hook and boom; New Bee gives S/M/L tips with a 180° swivel and 270° boom. Both cover left and right ear wear.
• Best for two-device switching → a tie. Both pair with two Bluetooth devices simultaneously; Kelazola states 33 ft range, New Bee states 15 m (roughly 49 ft).
• Best for privacy on calls → a tie. Both give you a mute control, which is the feature I'd want in any shared office or open-plan setting.
In my opinion, Kelazola Headset V5.1 is the one I'd buy if calls are your job and charging is your annoyance — 100 hours of talk time and 90 days of standby is the kind of headroom that changes how you use a headset. I'd pick New Bee Headset V5.1 instead if I were driving, moving between sites, or wanted a case I could throw in a bag with a battery readout I can actually see. Kelazola wins on endurance; New Bee wins on portability and power flexibility. If you're genuinely torn, buy the one whose weak point you can live with — running to a charger, or carrying a case.
FAQ
how to bluetooth headset to pc
how to bluetooth headset to ps5
The PS5 doesn't accept standard Bluetooth audio headsets directly, so a USB Bluetooth transmitter is the usual workaround. Both of these are Bluetooth 5.1 single-ear call headsets with 3.5mm-free wireless connectivity — Kelazola has no headphone jack at all, while New Bee lists a 3.5 mm jack. Even so, neither is marketed as a gaming headset.
how to bluetooth headset to xbox series s
Xbox consoles also block direct Bluetooth audio pairing, so you'd need a transmitter or a controller-side adapter. These headsets are built for calls — Kelazola for office and driving, New Bee for driving, business calls and laptops — so treat console use as a workaround, not a designed feature.
how to bluetooth headset to xbox
Same situation as the Series S: Xbox doesn't pair with Bluetooth headsets natively. Pair them with a phone, PC or laptop instead, where both work out of the box over Bluetooth 5.1. If console audio is your main goal, these two aren't the right tools for it.
If you're ready to compare them properly, check the current price on Amazon for each and match it against the feature you actually care about — runtime with Kelazola, or the charging case with New Bee.
