If you want an open-ear headset built for all-day office work and video calls, choose YOLAXGA Open Ear; if you need marathon battery life and a charging case that doubles as a power bank, choose hadbleng Earbuds 128hrs. These two earbuds sit at opposite ends of the "earbuds with long battery" conversation, and which one wins depends entirely on how you plan to wear them.
• YOLAXGA Open Ear — biggest strength: A 180° rotating single earbud that clips outside your ear, so you keep full awareness of your surroundings while staying on calls. It's rated for up to 30 hours of playback or talk time on a single charge.
• YOLAXGA Open Ear — biggest trade-off: It's a single-ear, open-ear design. If you want stereo music immersion or a sealed-in fit, this isn't that product.
• hadbleng Earbuds 128hrs — biggest strength: A 2600 mAh charging case that pushes total playtime to roughly 120 hours, with an 8-hour single-charge rating and enough reserve to top up your phone in a pinch.
• hadbleng Earbuds 128hrs — biggest trade-off: It's a bulkier over-ear-hook sport bud with a large case. That extra capacity has to live somewhere.
• Who each pick is for: Choose YOLAXGA if your day is meetings, calls and quiet focused work; choose hadbleng if your day is running, workouts, travel and long stretches away from a charger.
The YOLAXGA Open Ear is a single-ear headset, not a pair of stereo earbuds, and that single fact explains almost everything about it. The speaker arm rotates a full 180 degrees, so you can wear it on your left or right ear depending on which side you prefer or which ear is free. It weighs just 27 grams, and because it rests outside your ear rather than plugging into the canal, there's no in-ear pressure building up over a long day. For anyone who has ever pulled an earbud out after a three-hour block of back-to-back calls because their ear felt sore, that design choice is the whole point.
It runs Bluetooth 5.0 with a 10-meter range and connects to Android, iOS and laptops, and the on-ear touch controls handle calls, volume and playback without reaching for your phone. The 200 mAh battery is rated for up to 30 hours of playback or talk time and charges in about an hour. Audio is handled by a dynamic driver with a stated frequency range of 20 Hz to 2000 Hz and 8-ohm impedance, and the listing includes adaptive noise cancellation for calls. In practice, this is a headset tuned for speech clarity in home offices, corporate workplaces and other quiet settings rather than a music-first product.
So who should buy it? If you work from a desk, live in video conferences, or want to hear a colleague walk up behind you while you're listening to something, this is the fit. It's also a sensible pick for driving, cycling or running where staying aware of traffic matters. Who should skip it? Anyone who wants two earbuds, deep bass for music, or a sealed fit that blocks out a noisy open-plan office. This is an awareness-first tool, not a noise-isolating one.
The hadbleng Earbuds 128hrs are built around one number: battery. The buds themselves are rated for 8 hours of playtime, and the 2600 mAh charging case extends that to roughly 120 hours of total playback. A dual LED display on the case shows both the remaining case power and each bud's charging status, which takes the guesswork out of when to plug in. The case recharges over USB-C in about 2 hours.
There's a genuinely clever extra here: that 2600 mAh case can also charge your phone, tablet or other devices in an emergency, and the listing claims it can push more than 30% into a phone when fully charged. If you've ever been stranded with a dead phone and no outlet, that's a real-world feature, not a spec-sheet curiosity.
On the audio side, hadbleng uses 13 mm dual-layer graphene diaphragm drivers with bass-enhancement tuning, plus hybrid ENC noise cancellation on the mic that the listing says passively cuts about 90% of background noise. Connectivity is Bluetooth 5.3 with a 15-meter range and one-step auto-pairing after the first connection. The buds weigh 6 grams each, use flexible earhooks and ship with three sizes of silicone tips, and they carry an IPX7 waterproof rating — enough to shrug off rain and sweat. Smart touch controls cover tracks, volume, calls and a voice assistant.
Who should buy these? Runners, gym-goers, cyclists and travelers who want long sessions without hunting for a charger, plus anyone who likes the idea of a case that can bail out their phone. Who should skip them? If you specifically want an open-ear design that keeps your ear canal clear and your surroundings audible, these seal into the canal and sit over the ear with hooks — a different experience entirely.
Side-by-Side: Which Should You Choose?
• Best for battery life → hadbleng Earbuds 128hrs. An 8-hour single-charge rating plus a 2600 mAh case for roughly 120 hours total is the longer runway by a wide margin.
• Best for workouts, running and rain → hadbleng Earbuds 128hrs. IPX7 waterproofing plus flexible earhooks and three tip sizes make it the sport-oriented pick.
• Best for staying aware of your surroundings → YOLAXGA Open Ear. The clip-on open-ear design lets you hear colleagues and traffic while audio plays.
• Best for music depth → hadbleng Earbuds 128hrs. Dual 13 mm graphene drivers with bass enhancement are aimed at immersive listening; YOLAXGA is tuned for voice.
• Best for travel and emergencies → hadbleng Earbuds 128hrs. The case can recharge your phone when you're away from an outlet.
• Best for a single-ear, low-pressure fit → YOLAXGA Open Ear. Nothing enters your ear canal, so there's no in-ear fatigue over long stretches.
• Best for stereo calls and media on the move → hadbleng Earbuds 128hrs. Two buds, Bluetooth 5.3 and a 15-meter range give you more freedom and fuller sound.
In my opinion, most people shopping the phrase "earbuds with long battery" want exactly what the hadbleng Earbuds 128hrs deliver: an 8-hour single charge, a 2600 mAh case that stretches total playtime to around 120 hours, IPX7 durability and a case that can rescue your phone. That combination covers workouts, commutes and travel without anxiety. I'd pick the YOLAXGA Open Ear only if my priority were open-ear awareness and a single, pressure-free bud for calls and office work — which it does very well, but for a narrower job. For the broadest everyday use, I'd buy the hadbleng.
how long earbuds battery last
It varies widely by design. The hadbleng Earbuds 128hrs are rated for 8 hours per charge with roughly 120 hours total via the 2600 mAh case. The YOLAXGA Open Ear is rated for up to 30 hours of playback or talk time on its 200 mAh battery. Always match the rating to how you actually use them.

Look for a high single-charge rating plus a large charging case. The hadbleng Earbuds 128hrs pair an 8-hour bud rating with a 2600 mAh case for about 120 hours total. The YOLAXGA Open Ear takes a different route, offering up to 30 hours in a single lightweight bud with no case needed.
