If you want a no-fuss pair of IPX7 waterproof earbuds with a big charging case and a proven fit for running and workouts, choose Jectse Earbuds; if you need newer Bluetooth, a clearer call setup, and a visible battery readout for long sport sessions, choose STECEi Earbuds.
• Jectse Earbuds — biggest strength: IPX7 waterproofing plus an ergonomic in-ear sports design and a 1200mAh charging case that keeps the buds topped up on the go.
• Jectse Earbuds — biggest trade-off: Bluetooth 5.1 (an older version than the STECEi pair) and roughly 4 hours of talking time per charge, with no noise control at all.
• STECEi Earbuds — biggest strength: Bluetooth 5.3, 13mm dynamic drivers with triple-layer composite diaphragms, and an ENC noise-cancelling mic for calls.
• STECEi Earbuds — biggest trade-off: The datasheet lists it as a Red, in-ear model with push-button controls and no charging-case capacity figure, so you're trusting the buds themselves rather than a stated case battery.
• Who Jectse fits: Anyone who wants a simple, sweat-and-rain-proof sports earbud with a large included charging compartment.
• Who STECEi fits: Anyone who cares more about call clarity, newer Bluetooth, and on-screen battery info than about case capacity.
The Jectse Earbuds are built around one clear idea: keep them on your head while you move, and keep them charged without thinking about it. The IPX7 rating means they're protected from sweat and rain, which is the single most useful spec for anyone who runs, lifts, or trains outdoors. The ergonomic in-ear shape is designed for that same active use, and the transmission distance of about 10 meters gives you normal room-to-room freedom from your phone or laptop.
The charging setup is the other standout. The included compartment holds a built-in 1200mAh battery and is described as giving 24 hours of use on a single charge, with the buds charging automatically every time you drop them back in. Each earbud carries a 50mAh battery and delivers about 4 hours of talking time, and a full charge takes roughly 1.5 hours. Because the buds refill themselves in the case, the 4-hour figure matters less in practice than it looks on paper.
I'd point a gym-goer, a casual runner, or someone who wants one pair for commuting and workouts at this one. I'd steer away anyone who spends hours on calls, wants active noise cancellation, or cares about having the newest Bluetooth version.
STECEi Earbuds: Who It's For
The STECEi Earbuds lean toward audio and call quality rather than raw battery specs. The headline feature is the 13mm dynamic driver paired with triple-layer composite diaphragms, which the datasheet says is tuned for enhanced bass and treble. That's a bigger driver than you typically see in small sport buds, and it's the reason I'd expect these to sound fuller than their size suggests.
The second differentiator is the ENC noise-cancelling microphone. Environmental Noise Cancellation works on the mic side — it reduces background noise on your end of the call so the person you're talking to hears you more clearly. That's a genuinely useful thing for anyone taking calls while walking, cycling, or in a noisy gym, and it's the feature the Jectse pair simply doesn't offer.
You also get Bluetooth 5.3, which is a newer generation than 5.1 and generally means a more efficient, more stable link. The earbuds are in-ear with a Red finish, weigh 100g as a package, and use push-button controls rather than touch — a detail some people prefer because buttons don't misfire when you adjust the bud. There's an LED display on the case for battery status, which removes the guesswork about how much charge is left. The datasheet also lists a 2-year warranty description, and there's no headphone jack, as you'd expect from a wireless set.
Skip these if you specifically want a documented large-capacity charging compartment or if you prefer touch controls. Buy them if clear calls, stronger bass, and modern Bluetooth matter more to you than a stated case battery number.
• Best for waterproof sport use → both, honestly. Both carry an IPX7 rating for the earbuds themselves, so sweat and rain are covered either way.
• Best for call clarity → STECEi Earbuds. The ENC noise-cancelling mic is a dedicated call feature; Jectse lists no noise control.
• Best for battery confidence on the go → Jectse Earbuds. A 1200mAh charging compartment rated for 24 hours of use is the more generous setup on paper.
• Best for newer connectivity → STECEi Earbuds. Bluetooth 5.3 versus Bluetooth 5.1.
• Best for sound hardware → STECEi Earbuds. 13mm dynamic drivers with triple-layer composite diaphragms.
• Best for control style → depends on taste: Jectse gives you a wake-up voice assistant and simple pairing; STECEi gives you physical push buttons that won't trigger by accident.
• Best for battery visibility → STECEi Earbuds. The LED display shows status at a glance.
• Best for warranty coverage → STECEi Earbuds, which lists a 2-year warranty description.
In my opinion, the STECEi Earbuds are the better pick for most people. Bluetooth 5.3, 13mm drivers, an ENC mic for calls, an LED battery display, push-button controls, and a listed 2-year warranty description add up to a more complete everyday package — and they still carry the IPX7 waterproofing that makes either pair viable for sport. I'd only choose the Jectse Earbuds if the large 1200mAh charging case and its 24-hour claim are the thing you care about most. Check the current price on Amazon before deciding, since that's the one variable neither datasheet settles.
are headphones waterproof
Not as a category — it depends on the rating. Both the Jectse Earbuds and the STECEi Earbuds are rated IPX7 for the earbuds themselves, meaning they're protected from sweat and rain. Note that the Jectse charging case is specifically stated as not waterproof, so keep the case dry even though the buds can take moisture.
Many are, and IPX7 is a step beyond basic water resistance — it covers sweat, rain, and brief immersion for the earbuds. Both pairs here use IPX7, so for running, gym work, or wet-weather commuting, either one is designed to hold up. Just don't treat the charging case as water resistant unless the datasheet says so.
Do I need to worry about battery life with the Jectse Earbuds?
The buds themselves give about 4 hours of talking time and take about 1.5 hours to charge. The 1200mAh charging compartment is rated for 24 hours of use on a single charge and recharges the buds automatically when you put them back in, so the practical runtime is longer than the per-bud figure suggests.
Based on the specs, the STECEi Earbuds. They include a built-in ENC noise-reduction mic for call noise cancellation, while the Jectse Earbuds list no noise control feature. If clear calls in noisy places matter to you, that's the deciding spec.
