If you want marathon battery life and a charging case that doubles as a backup power bank, choose VleenVl Headphones; if you need a lighter, simpler sports earbud with physical buttons and four sizes of ear tips for a locked-in fit, choose KALOC Headphones.
• VleenVl Headphones biggest strength: A 2000mAh charging case that the brand says can refill the buds about 25 times, plus a claimed 40 hours of playtime per cycle and even emergency phone top-ups.
• VleenVl Headphones biggest trade-off: Touch controls only, and a bulkier case that exists mainly to carry that big battery.
• KALOC Headphones biggest strength: A lightweight in-ear sports design with physical button controls, four ear tip sizes (XS/S/M/L) and active noise cancellation.
• KALOC Headphones biggest trade-off: Shorter battery life — 12 hours of listening per charge, 250 hours standby, and a 2-hour charge time — with no charging case mentioned.
• Who VleenVl is for: Anyone who hates charging, travels a lot, or wants the case itself to be useful.
• Who KALOC is for: Runners and gym-goers who want a secure fit, real buttons, and don't mind charging more often.
The VleenVl YX-01 is built around one idea: never think about charging. The earbuds themselves are rated for up to 40 hours of playtime, and the included 2000mAh case can reportedly recharge them roughly 25 times over. That case also works as an emergency power source for your phone, which is an unusual trick for a set of budget in-ear buds. If you're the type who throws earbuds in a bag and forgets about them for a week, this is the design that forgives you.
Audio and connection specs are straightforward: a Bluetooth 5.0 chip for a stable link with less transmission loss, and CVC8.0 noise reduction that the brand says intelligently filters environmental noise. In practice that's call-focused noise handling rather than full active noise cancellation, so don't expect the world to go silent — expect your voice to come through more clearly on calls in noisy places. The IPX7 rating is the real headline for active use: sweat-proof and rain-proof, and the brand lists running, biking, driving, camping and climbing as intended scenarios.
Controls are touch-based — play/pause, Siri activation, and call answer/end with a tap. Pairing is genuinely simple: pull both buds from the case, they link to each other, then you tap "TWS" once in your phone's Bluetooth list. In the box you get the two earbuds, the case, a Type-C cable, three pairs of silicone earplugs (one already on the buds) and a manual.
Who should skip it: anyone who specifically wants active noise cancellation, physical buttons, or a choice of ear tip sizes — none of those are part of this package.
KALOC Headphones: Who It's For
The KALOC U8 takes the opposite approach. Instead of a giant battery, it leans on fit and usability. The buds are described as lightweight and flexible, shaped to sit in the ear without falling out during vigorous exercise, and KALOC ships four ear tip sizes — XS, S, M and L — specifically so long listening sessions don't turn painful. That sizing range matters more than people admit; a bad seal ruins bass and makes buds pop loose mid-run.
Sound and connection are handled by a dynamic driver for what KALOC calls HiFi bass stereo, paired with Bluetooth 5.0 and a stated 10-meter range. Noise handling is where this one pulls ahead of the VleenVl on paper: it lists active noise cancellation as a noise control feature, plus CVC 6.0 noise reduction for call clarity. So you get two layers — ANC to quiet your surroundings, and voice processing to clean up your mic.
The controls are physical buttons on the headset: volume up/down, next/previous track, play/pause, and call answer/end. No tapping, no guessing, and buttons work reliably with sweaty or gloved hands, which is exactly why runners tend to prefer them. The IPX7 rating is backed by what KALOC describes as nano-layer technology to resist sweat and rain penetration.
Battery is the clear compromise: up to 12 hours of listening and 250 hours of standby, with a 2-hour charge time. There's no charging case mentioned — the included accessories are a cable, an earphone bag and earplugs. The color is green.
Who should buy it: runners, gym users, and anyone who wants active noise cancellation, tactile buttons and a genuinely adjustable fit.
Who should skip it: frequent travelers, people who want a case that recharges the buds on the go, and anyone who needs more than roughly 12 hours between charges.
• Best for battery life → VleenVl Headphones. Up to 40 hours per cycle plus a case rated for about 25 recharges is a different category of endurance than 12 hours.
• Best for travel and emergencies → VleenVl Headphones. The 2000mAh case can top up your phone, which no other feature here replicates.
• Best for noise cancellation → KALOC Headphones. It explicitly lists active noise cancellation; the VleenVl relies on CVC8.0 call noise reduction instead.
• Best for running and gym work → KALOC Headphones. Lightweight flexible build, four ear tip sizes, and a stated no-slip fit during vigorous exercise.
• Best for controls you can feel → KALOC Headphones. Physical buttons for volume, tracks and calls beat touch taps when your hands are wet or moving.
• Best for fit customization → KALOC Headphones. XS/S/M/L tips versus the VleenVl's three pairs of silicone earplugs.
• Best for call clarity in noisy places → a tie, with different methods. CVC8.0 (VleenVl) and CVC6.0 (KALOC) both target environmental noise on calls.
• Best for charging convenience → depends on your habits. VleenVl gives you a case that recharges on the move; KALOC gives you a 2-hour charge and no case to carry.
In my opinion, the VleenVl Headphones are the smarter buy for most people, because the 2000mAh case and 40-hour rating solve the problem that actually annoys earbud owners — remembering to charge. The phone top-up feature is a genuinely useful bonus for travel and camping.
That said, if you're a runner who wants active noise cancellation and buttons you can press without looking, I'd point you to the KALOC Headphones instead. Just go in knowing you'll charge more often and you won't get a charging case. Check the current price on Amazon for both before deciding — the value math shifts a lot depending on what each is going for when you buy.
FAQ
Yes — KALOC lists active noise cancellation as a noise control feature, along with CVC 6.0 noise reduction for calls. The VleenVl Headphones don't list ANC; they use CVC8.0 noise reduction, which targets call clarity rather than blocking background sound.
VleenVl claims up to 40 hours of playtime, and its 2000mAh case can reportedly recharge the buds about 25 times. KALOC claims up to 12 hours of listening and 250 hours of standby, with a 2-hour charge time and no charging case mentioned.
That's personal preference. VleenVl uses touch controls for playback, Siri and calls. KALOC uses physical buttons for volume, tracks, play/pause and calls. Buttons are easier to use with gloves or sweaty hands; touch is cleaner-looking and needs no pressure.
I can't quote prices here, and honestly the answer depends on what each costs when you're shopping. If the VleenVl is close in price, its battery case is the stronger long-term feature. If the KALOC is notably cheaper, its ANC and button controls make it a solid sports pick. Check the current price on Amazon for both.
