If you want an open-ear clip design that keeps you aware of traffic and your surroundings, choose Ugreen HiTune S3; if you need marathon battery life and a charging case that can top up your phone, choose hadbleng Ear Buds.
• Ugreen HiTune S3 — biggest strength: an open-ear C-shape clip that weighs just 5.3g per bud, so nothing plugs your ear canal and you stay aware of cars, bikes and people around you.
• Ugreen HiTune S3 — biggest trade-off: the clip tops out at a maximum size of 2.5 cm, and Ugreen itself warns these may not fit larger ears. The open design also means less passive isolation, and there is no companion app.
• hadbleng Ear Buds — biggest strength: a 2600 mAh charging case that pushes total listening toward 120–128 hours, plus a digital display showing exactly how much power is left.
• hadbleng Ear Buds — biggest trade-off: these are over-ear hook buds that seal into the canal, so you lose the awareness an open design gives you — and they are a bulkier thing to carry.
• Who each pick is for: the Ugreen HiTune S3 suits runners, cyclists and drivers who want to hear the world; the hadbleng Ear Buds suit long-shift workers, travellers and anyone who hates hunting for a charger.
The HiTune S3 is built around one idea: keep your ears open. Each bud weighs 5.3g and uses a C-shape clip that hooks onto the edge of your ear rather than sealing the canal. That single design choice drives everything else about it — you get 12mm drivers pumping sound toward your ear from the outside, and because nothing is jammed in your ear, you stay fully aware of traffic, footsteps and conversation. For cyclists, hikers and anyone running near roads, that is the whole point. It is also why Ugreen builds in nano-coated components and an IPX5 rating, so sweat and rain are not an immediate problem.
The spec sheet shows Bluetooth 5.4, a 10-metre wireless range, and a Game Mode with 0.08s low delay for people who care about audio sync. Calls lean on AI noise cancelling and environmental noise cancellation, with Ugreen claiming a 98% reduction in sound leakage — useful if you take podcasts or meetings in shared spaces. Battery is 7.5 hours per charge and 30 hours total, and a 15-minute USB-C top-up buys roughly 120 minutes of playback. Controls are touch only, there is no app, and the buds ship with a USB-C cable, a manual and a 2-year manufacturer warranty.
So who should buy it? In my opinion, this is the pick for someone whose priority is safety and lightness: runners on open roads, cyclists in traffic, drivers who want audio without blocking a horn, and people who find in-ear tips uncomfortable after an hour. Who should skip it? Anyone with larger ears — Ugreen's own reminder says the 2.5 cm maximum may not fit — and anyone who wants deep isolation on a noisy train or a plane. This design deliberately lets the outside world in.
The hadbleng Q22 goes the opposite direction: it wants to be the last pair you charge for a week. The headline is battery — 8 hours in the buds, a 2600 mAh charging case, and up to 120 hours of total playback, with the case itself rated at 128 hours in the spec sheet. That is an enormous reserve, and hadbleng pairs it with a dual LED digital display that shows remaining case power and bud charging status, so you never guess. Fully charged, that same case can also push more than 30% charge into a phone in an emergency — a genuinely useful trick if you travel or work long days away from an outlet.
Audio hardware is a 13mm dual-layer graphene diaphragm driver with bass-enhancement algorithms, plus hybrid ENC noise cancelling and a mic that hadbleng says passively eliminates 90% of background noise. Connectivity is Bluetooth 5.3 with a 15-metre range and one-step auto-pairing once the first connection is made. The fit is over-ear hooks with three sizes of silicone tips (S/M/L), 6g per bud, and an IPX7 waterproof rating — a step above splash resistance, which matters for heavy sweat and rain. Controls are touch, with voice-assistant support.
Who should buy it? In my opinion, the Q22 fits shift workers, delivery riders, gym-goers, students and frequent travellers — anyone who wants to leave the charger at home and still have power left over for their phone. Who should skip it? Cyclists and road runners who specifically want to hear their surroundings. Passive noise cancellation plus a sealed ear canal means the world gets muffled, and the hook-plus-tips fit is more hardware on your head than a 5.3g clip. The case is also a 2600 mAh brick rather than a pocket-friendly pebble.
• Best for situational awareness → Ugreen HiTune S3. Open-ear clip, nothing in the canal, aural awareness is the design goal.
• Best for total battery life → hadbleng Ear Buds. 120 hours of playback and a 128-hour case versus 30 hours total on the Ugreen.
• Best for charging convenience → hadbleng Ear Buds. The digital display plus emergency phone charging make the case a power bank.
• Best for all-day lightness → Ugreen HiTune S3. 5.3g per bud with a 2.5 cm maximum clip size — light, but check your ear size first.
• Best for water and sweat exposure → hadbleng Ear Buds. IPX7 versus IPX5; both handle sweat, but IPX7 goes further.
• Best for calls in shared spaces → Ugreen HiTune S3. AI noise cancelling for voice pickup plus a claimed 98% reduction in sound leakage.
• Best for synced audio and gaming → Ugreen HiTune S3. Bluetooth 5.4 and a 0.08s low-delay Game Mode.
• Best for wireless freedom around the house → hadbleng Ear Buds. A 15-metre range versus 10 metres on the Ugreen.
I would buy the Ugreen HiTune S3. The reason is simple: the open-ear clip solves a problem that matters to me more than battery numbers — hearing what is happening around me while I run, ride or walk. It is lighter, it leaks less sound, and Bluetooth 5.4 with a low-delay Game Mode is the more modern connection. I would only switch to the hadbleng Ear Buds if battery anxiety is my real enemy, I want a case that can rescue my phone, and I do not mind sealing my ears. Check the current price on Amazon for both before deciding — the value gap is the one thing specs cannot tell you.
FAQ
Not universally. The HiTune S3 wins on openness, weight and low-latency Bluetooth 5.4. The hadbleng Q22 wins on battery life, water resistance and a charging case that doubles as a power bank. Pick by use case, not by brand.
The spec sheet lists 8 hours per charge, a 2600 mAh case, 120 hours of total playback and a 128-hour case rating. Real time depends on volume, so treat those as maximum figures.
Yes — that is their purpose. The 5.3g clip and IPX5 rating suit running and cycling, and the open design keeps you aware of traffic. Just confirm the 2.5 cm maximum clip fits your ears.
Both claim noise-cancelling mics. The Ugreen uses AI noise cancelling plus environmental noise cancellation and reduced leakage; the hadbleng uses hybrid ENC with a mic that cuts background noise. For quiet-room clarity, I would lean Ugreen; for loud environments, either is a reasonable bet.
