If you want maximum battery life, a secure in-ear sport fit and water protection you can sweat through, choose sprtoybat Earbuds; if you need open-ear awareness, a fit that never enters your ear canal and a design that works for both adults and kids, choose Yeforu Semi Open Ear.
• sprtoybat Earbuds biggest strength: a huge 68-hour total playtime with a charging case, IPX7 water protection and Bluetooth 5.4 — built for long, sweaty training blocks.
• sprtoybat Earbuds biggest trade-off: they sit inside your ear canal, so you stay sealed off from traffic, training partners and ambient sound.
• Yeforu Semi Open Ear biggest strength: an open, wraparound hook design that keeps your ear canal clear, so you hear your surroundings while you listen.
• Yeforu Semi Open Ear biggest trade-off: 5–7 hours per charge, 35 extra hours in the case, and no stated waterproof rating — it asks more charging discipline and more care.
• Pick sprtoybat Earbuds if you run, lift or ride and want one charge to cover a whole week of workouts.
• Pick Yeforu Semi Open Ear if you prioritise hearing protection, situational awareness, or want a headphone you can share with a kid.
The sprtoybat Earbuds are a classic sport earbud built around endurance. The headline number is 68 hours: 8 hours on a single charge, with the portable case topping the buds up 8–9 times. Ten minutes of Type-C charging buys you 2 hours of music, and a full charge takes about 2 hours. If you're the kind of person who forgets to charge things, that maths matters more than any spec sheet buzzword.
Sound is handled by 14.2mm dual-layer graphene drivers, with a frequency range of 20Hz–20,000Hz and a dynamic driver setup. That's a bass-forward, full-range tuning on paper — the kind of profile that suits gym playlists and podcasts rather than critical listening. The built-in ENC microphone is rated to cut background noise by 75%, which is the difference between a call your colleagues understand and one they don't.
Who should buy it? Runners, cyclists, gym regulars and anyone who wants one pair to cover work calls, commutes and training. Who should skip it? Anyone who needs to hear traffic or a coach's voice, and anyone who finds in-ear tips uncomfortable over long sessions. The hook helps, but the nozzle still goes in your ear.
Yeforu Semi Open Ear: Who It's For
The Yeforu Semi Open Ear takes the opposite approach. The speaker unit hangs near your ear without entering the canal at all, held by 360° wraparound hooks that the brand says are shaped to suit different ear sizes — including children's. That's the whole point of the design: air and sound get in, so your ear stays breathable and you stay aware of what's around you.
The awareness angle is the real selling point. Yeforu explicitly frames this as hearing protection, arguing that because nothing is jammed into the canal, the buds help prevent excessive volume damage and deliver a more natural listen. If you run on roads, ride a bike, or want to hear a car, a dog or a teammate coming, an open design is the safer choice. Yeforu also says the suspended speaker produces clearer, louder sound while reducing leakage — a common weak spot for open designs, so that claim is worth testing against your own expectations.
Battery is where it gives ground. You get 5–7 hours per charge, with the case adding 35 hours, and the case fully recharges in about an hour. For a single long session that's fine. For a week of daily two-hour workouts, you'll be reaching for the cable more often than with the sprtoybat pair.
Two other things to plan for. First, Yeforu states plainly that you should spend 10–30 seconds adjusting the angle to lock the fit, and that a short adaptation period is normal for first-time open-ear users. Second, the model is listed as K18-Multi and the brand notes patterns on printed styles are randomly assigned, so what arrives may not match the photo exactly. The manufacturer lists the age range as Adult and Kid, though it stresses it isn't suitable for very young children. Water resistance is described as sweatproof and waterproof in the marketing copy, but unlike the sprtoybat's IPX7, there's no formal rating to lean on — so treat heavy rain with some caution.
• Best for battery life → sprtoybat Earbuds. 68 hours total versus 35 hours in the case plus 5–7 per charge.
• Best for hearing protection and awareness → Yeforu Semi Open Ear. Nothing enters the ear canal, so you hear your surroundings.
• Best for intense sweat and rain → sprtoybat Earbuds. IPX7 is an actual rating; Yeforu's water protection is claimed without a stated grade.
• Best for kids or shared use → Yeforu Semi Open Ear. Listed for adults and kids with wraparound hooks sized for varied ears; the sprtoybat is listed for adults.
• Best for long training blocks → sprtoybat Earbuds. 8 hours per charge and a 10-minute top-up for 2 hours of playback.
• Best for calls in noisy places → sprtoybat Earbuds. The ENC mic is rated to reduce background noise by 75%.
• Best for a first open-ear experiment → Yeforu Semi Open Ear. Budget the 10–30 seconds of angle adjustment and a short adaptation period.
• Best for wireless freedom and range → sprtoybat Earbuds. Bluetooth 5.4 with a stated 15-metre range and touch controls.
In my opinion, the sprtoybat Earbuds are the better buy for most people shopping this category. The reason is simple: 68 hours of total playback, IPX7 water protection and Bluetooth 5.4 cover the two things that actually break sport earbuds — running out of power and dying from sweat. The Yeforu Semi Open Ear does one job brilliantly, and if you cycle in traffic, run on open roads or want a pair a child can use, that one job is worth more than every spec above. But if you just want a tough, long-lasting pair for the gym, I'd take the sprtoybat. Check the current price on Amazon before you commit.
For sweat and battery, yes — sprtoybat offers IPX7 protection and 68 hours of total playtime. For road running where you need to hear traffic, the Yeforu's open design is the safer pick.
Yeforu uses 360° wraparound hooks designed for different ear shapes and says they hold securely. The brand does note you should spend 10–30 seconds adjusting the angle and allow a short adaptation period, so expect a bit of fiddling at first.
sprtoybat gives 8 hours per charge with 68 hours total via the case. Yeforu gives 5–7 hours per charge with 35 extra hours in the case, which recharges in about an hour.
Yes — Yeforu lists the age range as Adult and Kid, and the open-ear design is pitched partly as hearing protection. The brand does state it isn't suitable for very young children, so supervise younger users.
