• hadbleng Ear buds — biggest strength: A 2600 mAh charging case that pushes total listening time to roughly 128 hours and can top up your phone in a pinch.
• hadbleng Ear buds — biggest trade-off: They sit in your ear canal with silicone tips and earhooks, so they block outside sound — not ideal if you want full awareness of traffic or training partners.
• DECHOYECHO Open Ear Headphones — biggest strength: An open-ear, air-conduction design that leaves your ear canal completely unobstructed and is explicitly built for people who wear glasses.
• DECHOYECHO Open Ear Headphones — biggest trade-off: Battery life is a single-charge affair at 12 hours, with no charging case to extend it.
• Pick hadbleng if long gym sessions, travel days and dead-phone emergencies are your reality.
• Pick DECHOYECHO if you run, cycle or hike near traffic and want to hear what's around you.
The hadbleng Q22 is a sport earbud built around one idea: never run out of power. The case packs a 2600 mAh battery, and combined with the buds themselves that works out to a claimed 128 hours of total playback — the buds alone are rated at 8 hours per charge, with about 120 hours coming from the case. A dual LED display on the case shows remaining power and charging status, so you're not guessing. Charging is over USB-C and takes about two hours for the case.
The 2600 mAh cell isn't just for the earbuds. It can also charge your phone, tablet or another device in an emergency, and the brand claims a full case can push a phone past 30%. That's a genuinely useful trick if you're the kind of person who's always at 4% on the train home.
Fit is the classic earhook-plus-silicone-tip setup. Each bud weighs 6 grams, three sizes of ear caps are included, and the whole thing is IPX7 waterproof — rated to handle splashes and rain. Touch controls cover track skipping, volume, calls and a voice assistant.
Who should buy it: Gym-goers, runners, commuters and travelers who want long battery, a secure over-ear hook, real bass and passive noise isolation. Who should skip it: Anyone who needs to hear ambient sound for safety, or who dislikes the sealed-in-ear feel.
DECHOYECHO Open Ear Headphones: Who It's For
The DECHOYECHO O2 takes the opposite approach. Instead of sealing your ear canal, it uses air-conduction technology to direct sound toward your ear while leaving the canal open. That's the whole point of an open-ear design: you get your music, but you also get the world around you. If you've ever pulled an earbud out at a crosswalk to check for cars, this is the category that solves that problem.
The O2 is specifically pitched at glasses wearers, which makes sense — an open-ear hook doesn't fight with a temple arm the way a bulky in-ear or over-ear headphone can.
Battery is 12 hours of continuous music and calls on a single charge, with 150 hours of standby. There's no charging case, but there is magnetic fast charging: 10 minutes gets you about an hour of playback. For a long hike or a marathon, that's a real convenience.
The drivers are 15 mm dynamic drivers — larger than the 13 mm in the hadbleng — and the brand claims richer bass and clearer highs from the bigger diaphragm. Bluetooth 5.3 handles the connection with a range of about 33 feet, and the O2 can pair to two devices simultaneously and switch between them, which is handy if you're moving between a phone and a laptop.
Controls are physical buttons rather than touch, which cuts down on accidental taps when you're sweaty or wearing gloves. There's a built-in mic for calls, but no active noise cancellation.
Side-by-Side: Which Should You Choose?
• Best battery life overall → hadbleng Ear buds. Roughly 128 hours total with the case versus 12 hours on a single charge for the DECHOYECHO.
• Best for hearing your surroundings → DECHOYECHO Open Ear Headphones. The open-ear, air-conduction design keeps your canal clear.
• Best for glasses wearers → DECHOYECHO Open Ear Headphones. It's built with that fit in mind.
• Best for noise isolation → hadbleng Ear buds. Sealed silicone tips plus hybrid ENC for calls.
• Best for emergency phone charging → hadbleng Ear buds. The 2600 mAh case doubles as a power bank.
• Best for dual-device switching → DECHOYECHO Open Ear Headphones. It pairs with two Bluetooth devices at once.
• Best for larger drivers → DECHOYECHO Open Ear Headphones. 15 mm dynamic drivers versus 13 mm.
• Best for button controls over touch → DECHOYECHO Open Ear Headphones. Fewer accidental taps mid-workout.
• Best for water resistance → hadbleng Ear buds. IPX7 rated for splashes and rain.
In my opinion, the hadbleng Ear buds are the better all-round buy for most people. The 128-hour total battery, the charging case that can rescue your phone, the IPX7 rating and the ENC call handling give you more capability across more situations — gym, commute, travel, calls. The DECHOYECHO O2 is the smarter choice if safety and awareness come first, or if you wear glasses and want a fit that doesn't fight them. If you're outdoors near traffic, go DECHOYECHO. Otherwise, I'd take the hadbleng.
Both are built for running. hadbleng gives you a secure earhook, IPX7 water resistance and far more battery. DECHOYECHO gives you open-ear awareness, which many outdoor runners prefer near roads.
No. They're open-ear by design with no noise cancellation, so ambient sound comes through. The hadbleng buds sit in your ear canal and isolate more.
hadbleng, by a wide margin. Its case takes total playback to about 128 hours, while DECHOYECHO runs 12 hours per charge with no case.
