How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want one device that covers your wrist, your calls and your music in a single wearable, choose Tuanzi X9; if you need earbuds that stay locked on your head through long, sweaty training sessions and keep going for days between charges, choose hadbleng Earbuds Sport 128H.
These two products look like they compete for the same buyer, but they don't really. One is a smartwatch that happens to hide a pair of earbuds inside it. The other is a dedicated set of sport earbuds built around an enormous battery case. The right pick comes down to what you actually do all day, not which one sounds fancier on paper.
• Tuanzi X9 biggest strength: true 2-in-1 design — a 1.85-inch smartwatch with a 240mAh body that recharges the TWS earbuds stored inside for 2–3 cycles, plus health monitoring, multi-sport tracking and NFC.
• Tuanzi X9 biggest trade-off: the earbuds are single-ear units at roughly 2.45g each and the watch is a chunky 145g on the wrist, so you trade audiophile sound and light weight for convenience.
• hadbleng Earbuds Sport 128H biggest strength: marathon battery life — 8 hours per charge, a 2600mAh case good for up to 128 hours, and that same case can top up your phone in an emergency.
• hadbleng Earbuds Sport 128H biggest trade-off: it's earbuds only. No screen, no health tracking, no watch functions — every feature serves listening and calls.
• Who each pick is for: Tuanzi X9 for someone who wants one gadget for fitness tracking, notifications and casual listening; hadbleng for the runner, gym-goer or cyclist who wants secure earhooks and near-endless playtime.
The Tuanzi X9 is a wearable that refuses to pick a lane. It's a rectangular smartwatch with a glass lens and a zinc-aluminum alloy frame, CNC-machined with a metal decorative ring, and it also works as a Bluetooth speaker and a Bluetooth headset. The earbuds live inside the main body, and that body doubles as their charging case — according to the specs, it can push 2–3 full recharge cycles into them. So you leave the house with one thing on your wrist and you've got music, calls and a speaker in one.
What I like about it: this is the pick for someone who hates carrying two things. Students, commuters, parents juggling a watch and earbuds — you get both, plus a speaker for a kitchen counter or a hotel room. The IP67 rating means it handles hand-washing and sweat without drama, and the silicone strap keeps it comfortable for all-day wear.
Who should skip it: if sound quality is your priority, this isn't the tool. The earbuds are compact singles built for convenience, not for deep bass or hybrid noise cancellation. And if you want featherweight earbuds for sprint intervals, the 145g watch body and inset earbuds aren't a sport-earbud replacement. It's a convenience-first device, and it's honest about that.
hadbleng Earbuds Sport 128H: Who It's For
The hadbleng Sport 128H (model Q22) is built around one idea: you should almost never think about charging. Each earbud runs 8 hours, and the 2600mAh charging case extends that to a claimed 120 hours of music playback, with the case itself rated up to 128 hours. A dual LED digital display on the case shows both the remaining case power and each earbud's charging status, so you're not guessing. Charging is over Type-C and takes about 2 hours for the buds and 2 hours for the case.
Sound is handled by 13mm dual-layer graphene diaphragm drivers with a bass-enhancement algorithm, covering a 20Hz–20,000Hz range. There's hybrid ENC noise cancellation on the mic side, and the spec sheet claims it passively removes around 90% of background noise on calls — useful if you take meetings outdoors or in a busy gym. Bluetooth 5.3 is on board with a 15-meter range, and after the first pairing the buds auto-connect when you pull them from the case.
The sports part is where it earns its name. Each earbud weighs about 6 grams, uses flexible earhooks plus over-ear placement, and ships with three sizes of silicone tips. That combination is designed so the buds don't shift during running, cycling or lifting. The rating is IPX7, which handles rain and heavy sweat. Controls are touch-based, covering track skipping, volume, calls and a voice assistant. And the case doubles as an emergency power bank — it can push more than 30% charge into a phone when you're stuck.
Side-by-Side: Which Should You Choose?
• Best for battery life → hadbleng Earbuds Sport 128H. 8 hours per bud plus a 2600mAh case rated up to 128 hours is in a different league from earbuds that live inside a watch.
• Best for all-in-one convenience → Tuanzi X9. Watch, earbuds and speaker in one 145g unit, with the body recharging the buds for 2–3 cycles.
• Best for running and high-sweat workouts → hadbleng Earbuds Sport 128H. Earhooks, over-ear fit, 6g per bud and IPX7 are purpose-built for movement.
• Best for fitness tracking and health monitoring → Tuanzi X9. Heart rate chip, multi-sport modes, pedometer, calories and mileage are all built in.
• Best for calls in noisy places → hadbleng Earbuds Sport 128H. Hybrid ENC with a noise-cancelling mic is a more focused calling setup than a watch-based headset.
• Best for notifications and daily reminders → Tuanzi X9. SMS, WeChat, WhatsApp, Facebook and more land on your wrist, plus calls can be answered or rejected there.
• Best for emergencies and travel → hadbleng Earbuds Sport 128H. The case can charge your phone by more than 30% when you're away from an outlet.
• Best for a first smartwatch that also plays music → Tuanzi X9. It covers the wearable basics and hands you earbuds as a bonus.
My Verdict
In my opinion, most people reading this should buy the hadbleng Earbuds Sport 128H — but only if they already own a watch or genuinely don't want one. It does the one job it was designed for extremely well: long-lasting, secure, sweat-proof listening with a case that can rescue your phone. If, on the other hand, you want a single device that tracks your heart rate, shows your messages and gives you earbuds in the same package, I'd pick the Tuanzi X9 instead. Decide which problem you actually have, and the choice makes itself. Either way, check the current price on Amazon before you commit — the button on this page will take you there.
The specs list 8 hours of playtime per charge and a 2600mAh case rated for up to 120 hours of playback, with the case itself at up to 128 hours. Charging takes about 2 hours for both the buds and the case.
Yes, in practice the earbuds are separate Bluetooth 5.0 units that pair on their own. The watch body works as their charging case, giving them 2–3 recharge cycles, but you don't need the watch functions to listen.
That's worth checking yourself, since pricing shifts constantly. Compare the current price on Amazon for both, and weigh it against what you need: a wearable with tracking, or sport earbuds with a huge battery case.
