These two products get compared a lot because both put "wireless earbuds" in the title, but they solve completely different problems. The iPhanmis X17 is a smartwatch that happens to store and charge a pair of earbuds. The Acjohtin Earbuds are a dedicated set of sport earbuds with no watch attached. Once you see that split, the decision usually makes itself.
• iPhanmis X17 — biggest strength: a 1.27-inch round AMOLED watch and a pair of earbuds in one, with the watch able to recharge the buds for 2–3 cycles.
• iPhanmis X17 — biggest trade-off: short music time (around 3.5 hours per earbud charge) and Bluetooth 4.0 on the watch side, which is older technology.
• Acjohtin Earbuds — biggest strength: up to 90 hours of total playtime with the case, 8 hours from a single charge, and Bluetooth 6.1 with four ENC microphones.
• Acjohtin Earbuds — biggest trade-off: it's earbuds only. No screen, no health tracking, no watch functions at all.
• Who the iPhanmis X17 is for: someone who wants to wear one thing on the wrist and still take calls and track health, and who likes the idea of the watch doubling as a charging case.
• Who the Acjohtin Earbuds are for: runners, gym-goers and commuters who want earbuds that stay locked in place and last through a long week of workouts.
The X17 is a 43mm round watch with a 1.27-inch AMOLED touch display at 360×360 resolution, a glass lens and a zinc aluminum alloy shell. It comes in Gold and is clearly aimed at a women's and youth audience — that's not my assumption, it's the positioning in the product data. If you like round watch faces over square ones, this is the shape you want.
The interesting part is the design trick: the earbuds live inside the watch. The watch battery is 205mAh and each earbud carries a 25mAh cell, and the watch can charge the earbuds for 2–3 cycles. So you're not hunting for a separate charging case — the thing on your wrist is the case. The earbuds themselves are deliberately short and low-grip, which the spec sheet frames as reducing long-term wear pressure. That's a real design intent, not marketing fluff: shorter stems and lighter shells generally mean less fatigue over a long day.
Who should buy it: someone who wants one device on the wrist that handles calls, health tracking and music, and who values not carrying a separate earbud case. Also a good fit if you want a round AMOLED watch and you'd rather not buy two products. It's IP67 waterproof, so splashes and handwashing are fine.
Who should skip it: if your priority is marathon listening sessions, the roughly 3.5-hour music time per earbud charge is the limiting factor. And if you're on a newer phone and care about the latest Bluetooth efficiency, the watch runs Bluetooth 4.0 while the earbuds run Bluetooth 5.0 — functional, but not cutting-edge. If you want the earbuds to be the star of the show, this isn't that product.
Acjohtin Earbuds: Who It's For
The Acjohtin Earbuds are the opposite philosophy: strip away everything except the listening experience and make that part excellent. The headline numbers are a 16.2mm dynamic driver, Bluetooth 6.1, four HD microphones with ENC noise reduction, up to 90 hours of total playtime with the case, 8 hours from a single charge, and IPX7 waterproofing.
Let's talk about that 16.2mm driver first, because it's the number most people skip past. Most everyday earbuds use noticeably smaller drivers. A 16.2mm unit moves more air, which is why the spec sheet talks about deep bass, clear treble and balanced mids. In practice, that means workout playlists and podcasts have body to them instead of sounding thin. If you've ever put in cheap buds and felt like the kick drum disappeared, this is the spec that fixes it.
The second thing that matters is Bluetooth 6.1. The data explicitly claims faster pairing, a steady 33ft range and ultra-low latency, and positions it above Bluetooth 5.4. Low latency matters more than people think — it's the difference between lip-sync being right and being slightly off during video, and between game audio landing on time or trailing behind. The four microphones with ENC blocking up to 45dB of background noise are aimed squarely at calls taken on a busy street or in a noisy gym.
Then there's the fit. These are over-ear hook earbuds with soft silicone hooks and S/M/L interchangeable tips. The hooks are the reason they stay put during running and cycling — the tip seals the ear, and the hook anchors it. Combined with IPX7, that's a product built for sweat, splashes and light rain. The LED digital display on the case shows real-time battery for both the buds and the case, which is a genuinely useful touch when you're heading out and don't want to guess.
Who should buy it: runners, cyclists, gym regulars, commuters and anyone whose day involves a lot of calls in imperfect environments. The 2-year warranty description is also worth noting for people who are hard on their gear.
Who should skip it: if you wanted a watch, this gives you nothing — no screen, no health metrics, no step counting. And if you dislike over-ear hooks and prefer a bare in-ear fit, the hook design is a feature you'd be paying for and not using.
• Best for battery life → Acjohtin Earbuds. 90H total with the case and 8H per charge beats roughly 3.5H of music time on the X17.
• Best for health tracking → iPhanmis X17. Heart rate, SpO2, sleep, female cycle, steps, calories and multi-sport modes are all built in.
• Best for calls in noisy places → Acjohtin Earbuds. Four mics with ENC rated to cut up to 45dB of background noise.
• Best for staying put during hard workouts → Acjohtin Earbuds. Over-ear hooks plus IPX7 versus IP67 on the watch.
• Best for carrying less stuff → iPhanmis X17. The watch is the charging case, so there's one item on your body instead of two.
• Best for sound hardware on paper → Acjohtin Earbuds. A 16.2mm driver is a bigger audio engine than what's implied for the X17's compact buds.
• Best for newer connectivity → Acjohtin Earbuds. Bluetooth 6.1 versus Bluetooth 5.0 on the X17 buds and 4.0 on the watch.
• Best for a round-screen wearable look → iPhanmis X17. 1.27-inch AMOLED, 360×360, 43mm, gold finish.
If I had to pick one, I'd buy the Acjohtin Earbuds. The reason is simple: earbuds are used more often and more intensely than a watch for most people, and the Acjohtin set wins on the things that actually annoy you day to day — battery anxiety, buds falling out mid-run, muddy bass and callers who can't hear you. Bluetooth 6.1, 90H total playtime, 16.2mm drivers, over-ear hooks and IPX7 cover the fundamentals properly.
That said, the X17 is the smarter buy if you specifically want a watch with built-in earbuds and health tracking, and you're fine with shorter listening sessions. It's a clever two-in-one, not a compromise product. Just decide which job matters more before you spend.
The Acjohtin Earbuds last far longer for listening — up to 90 hours total with the case and 8 hours per charge. The X17's earbuds run about 3.5 hours of music time per charge, though the watch can recharge them 2–3 times.
Yes, that's exactly what they're designed for. Over-ear silicone hooks plus S/M/L tips keep them locked in, and IPX7 handles sweat, splashes and light rain.
Yes. It supports Android 4.4 and above and iOS 8.0 and above through the FitCloudPro app, and it handles Bluetooth calls, notifications and health tracking on both platforms.
It depends on what you need, so check the current price on Amazon before deciding. If you want earbuds only, the Acjohtin set packs more audio and battery hardware. If you want a watch and earbuds in one purchase, the X17 covers two jobs at once.
