• Keenso Earbuds — biggest strength: a 1200mAh charging case that recharges the buds six to eight times, can top up your phone, and hides a built-in flashlight with an LED power display on the front.
• Keenso Earbuds — biggest trade-off: no touch controls, no noise-canceling mic, and no stated working time per charge, so it's a utility-first pick rather than a call-quality pick.
• Jiawu HiFi — biggest strength: 10mm drivers, a noise-canceling mic, and full touch control (playback, calls, volume, tracks, voice assistant) in a 6–8 hour package.
• Jiawu HiFi — biggest trade-off: a 300mAh case and 35mAh per bud means far less reserve power, and there's no flashlight or phone-charging trick.
• Who each pick is for: Keenso for commuters, campers and anyone who wants a backup battery in their pocket; Jiawu HiFi for runners, cyclists and people who take a lot of calls.
The Keenso story is really the case, not the buds. That case packs a 1200mAh lithium-ion battery, which the specs say is enough to charge the earbuds six to eight times over. Each bud carries a 50mAh cell, so the case is doing the heavy lifting here. There's also a Type-C port for fast recharging, and a front-facing flashlight you switch on with a long press — a genuinely useful extra if you're unlocking a door at night or digging through a bag in a dark parking lot.
The LED digital display is the other headline feature. Instead of guessing whether you have juice left, you get a number on the case. That sounds small until you've been caught with dead buds on a long trip. Keenso also auto-reconnects after the first pairing, so you pull them out and they hook back up to your phone without menu-diving. Wireless range is listed at roughly 10 meters (32.8 feet), which is standard for Bluetooth earbuds.
On sound, Keenso describes a soft composite diaphragm tuned for "rich stereo" with bass that isn't stuffy and a layered midrange. That's a warm, easy-listening tuning rather than a detail-chasing one. I'd buy Keenso if your priority is endurance, a visible battery readout, and a case that can rescue your phone mid-day. I'd skip it if you live on calls, want touch gestures, or need a noise-canceling mic — none of that is in the spec sheet.
Jiawu HiFi goes the other direction: it's built around the listening and calling experience. The 10mm drivers are the largest piece of hardware in either spec sheet, and Jiawu tunes them for powerful bass, warm mids and clear highs. Bigger drivers generally move more air, which usually means fuller low end — and that lines up with what the brand claims here.
The noise-canceling mic is the feature that separates it most from the Keenso. For calls, meetings or voice notes, a mic that suppresses background noise does more for you than any driver size. Jiawu also supports AAC, a codec that tends to make streamed music sound better than the basic SBC fallback on a lot of budget buds.
Then there's the control scheme. Touch-sensitive controls handle playback, calls, volume, track skipping and your voice assistant — all without reaching for your phone. If you run or cycle, that matters: you keep your hands where they are. The fit is described as secure and comfortable for extended wear, which is exactly the brief for running and outdoor sports. Battery is listed at 6–8 hours of working time per charge, with a 300mAh case and 35mAh per bud. I'd buy Jiawu HiFi if you take calls, want touch control, or need buds that stay put through a workout. I'd skip it if you want a case that can also charge your phone or a battery readout you can read at a glance.
Side-by-Side: Which Should You Choose?
• Best for battery reserve → Keenso Earbuds. A 1200mAh case that recharges the buds 6–8 times is in a different class from a 300mAh case.
• Best for call quality → Jiawu HiFi. The noise-canceling mic is the deciding feature if you talk on your buds.
• Best for sound hardware → Jiawu HiFi. 10mm drivers plus AAC support versus Keenso's soft-diaphragm stereo tuning.
• Best for travel and emergencies → Keenso Earbuds. The flashlight and phone-charging case are things no other spec here offers.
• Best for hands-free control → Jiawu HiFi. Volume, tracks, calls and voice assistant all live on the touch surface.
• Best for knowing your battery level → Keenso Earbuds. The LED digital display gives you a number instead of a guess.
• Best for fuss-free reconnecting → Keenso Earbuds. Automatic pairing after the first connection is spelled out clearly in the specs.
In my opinion, Jiawu HiFi is the better buy for most people — and it comes down to the two things you use every single day: how the buds sound and how they handle a phone call. The 10mm drivers, AAC support and noise-canceling mic cover both, and the touch controls make the whole thing feel less like a chore. The Keenso Earbuds win on pure utility: that LED display, the flashlight and the phone-charging case are genuinely clever, and the bigger battery reserve is real. If your buds mostly sit in a bag until you need them — travel, camping, a backup pair — I'd take the Keenso. For everything else, go Jiawu.
For running, yes — in my opinion. Jiawu lists a secure fit for extended wear, touch controls you can use mid-stride, and a stated 6–8 hours of working time. Keenso doesn't list touch controls or a per-charge working time, so it's harder to plan a long session around.
It depends on what you mean. Jiawu states 6–8 hours of working time per charge, which Keenso doesn't state at all. But Keenso's 1200mAh case recharges the buds 6–8 times and can charge your phone, against Jiawu's 300mAh case — so Keenso wins on total reserve.
Nothing in the Keenso spec sheet mentions a mic or call handling. Jiawu HiFi explicitly lists a noise-canceling mic for clear calls. If calls matter to you, that's the deciding spec.
Check the current price on Amazon for both before deciding — I don't quote prices here. Spec-wise, Jiawu gives you more everyday features (touch control, AAC, noise-canceling mic); Keenso gives you more hardware in the case (1200mAh, flashlight, LED display). Pick based on which of those you'll actually use.
