If you want straightforward wireless earbuds for teens, choose Spracht Zum Truly; if you need a smartwatch and earbuds combined for teens, choose Tuanzi JM03. Spracht is the more focused pick for listening, with up to 14 hours of music playback and sweat resistance. Tuanzi adds activity tracking, alerts, and calls in a watch, but its earbuds play for about 2.5 hours continuously.
Spracht Zum Truly vs Tuanzi JM03 at a Glance
• Tuanzi JM03’s biggest strength: a 1.28-inch touchscreen watch paired with earbuds, plus activity records, alerts, and health-monitoring features. Trade-off: the earbuds play continuously for about 2.5 hours and are not waterproof.
• Spracht Zum Truly is for: teens who mainly want wireless earbuds for music, calls, and workouts.
• Tuanzi JM03 is for: teens who want a wearable with notifications and activity features as well as earbuds.
Spracht Zum Truly is the more direct choice if the main job is listening. It pairs with Bluetooth devices such as smartphones and tablets, and it can connect to as many as two devices. That makes it useful for someone who switches between a phone and a tablet without wanting earbuds that do only one thing. It also supports stereo listening or using each bud separately, including separate use by two people.
Its up-to-14-hour music playback figure gives it a practical advantage for a long school day, travel, or a stretch of listening between charges. The stated recharge time is about 1.5 hours, and the case charges wirelessly. Those are useful details for a teen who wants a dedicated earbud set rather than a wearable with a shorter earbud listening window. The earbuds are sweat resistant and described as IPX7 waterproof, with protection stated for submersion up to three feet for 30 minutes. That makes them the more suitable option here for workouts or sweaty activity.
The in-ear design uses rounded tips, with eartips included. That may appeal to someone who prefers earbuds that sit inside the ear, though fit is personal and the sheet does not specify a range of tip sizes. There is also active noise cancellation listed, but no details about how it performs or how it changes listening. Skip Spracht if you specifically want a touchscreen watch, activity records, or wrist-based alerts alongside your earbuds.

Tuanzi JM03: Who It's For
The watch includes a set of activity and health-monitoring functions: step counting, calories, mileage, multiple sport modes, heart-rate tracking, sleep tracking, blood-pressure monitoring, and sedentary reminders. It also supports message and app reminders through BrandFit. For a teen who likes seeing activity records and notifications on their wrist, that feature mix gives JM03 a role Spracht does not fill. The stated watch battery use is five to 15 days, with more than 30 days of standby when used without the earbuds. Those figures are for the watch; the earbuds have their own much shorter continuous playback figure.
Compatibility is listed for Android 6.0 and above and iOS 8.0 and above. The watch is described as life waterproof, but the earbuds are not waterproof, and the sheet advises wiping sweat off before returning them to their case. That distinction matters if the wearer plans to exercise: the watch’s water description should not be taken as protection for the earbuds. Skip Tuanzi if you want earbuds for extended listening or need water resistance for the earbuds themselves.
• Best for longer earbud listening → Spracht Zum Truly. Its stated music playback is up to 14 hours, compared with about 2.5 hours of continuous playback for Tuanzi’s earbuds.
• Best for combining earbuds and a smartwatch → Tuanzi JM03. It has a touchscreen watch, activity records, alerts, alarms, and Bluetooth calling.
• Best for workouts where sweat or water exposure matters → Spracht Zum Truly. Its earbuds are sweat resistant and described as IPX7 waterproof. Tuanzi’s earbuds are not waterproof.
• Best for tracking daily movement → Tuanzi JM03. It records steps, calories, and mileage, and offers multiple sport modes.
• Best for switching between two paired devices → Spracht Zum Truly. It supports multipoint pairing with up to two devices.
• Best for wrist-based information alerts → Tuanzi JM03. Its watch supports information and app reminders through BrandFit.
• Best for an open ear headphones gift for teens → neither is an open-ear design. Spracht is listed as in-ear, while Tuanzi’s earbuds are described as TWS; consider whether the teen specifically wants an open-ear fit before choosing.
• Best for an ear clip headphones gift for teens → neither is listed as an ear-clip style. These products should be compared as in-ear or TWS options, not as clip-on headphones.
Buying Considerations
If the watch is the reason for considering Tuanzi, think about how often the teen would use its tracking and alert features. The JM03 combines the watch and earbuds in one product, but that does not mean the earbuds inherit the watch’s water description or battery life. The watch’s stated five-to-15-day use applies to the watch; earbud playback is about 2.5 hours continuously. For activity, the wearer would need to keep the earbuds dry and wipe away sweat before putting them back in their case.
Fit and everyday preference matter too. Spracht uses an in-ear design with rounded tips. Tuanzi’s supplied details describe TWS earbuds but do not give enough fit information to make a confident comfort comparison. Neither product is identified as a comfortable wireless headset for teens in a way that guarantees fit for every wearer. If comfort is the deciding factor, consider the teen’s preferred earbud style and whether they are comfortable wearing in-ear earbuds.
Finally, compare what comes in the package and the device requirements that matter to your household. Spracht includes a charging case, USB charging cable, and eartips; its compatibility is described broadly for Bluetooth devices. Tuanzi requires an Android device running version 6.0 or later, or iOS 8.0 or later, for the listed phone compatibility. For either option, check the current price on Amazon using the page’s button rather than assuming the combination device or the dedicated earbuds are the better value.
I would choose Spracht Zum Truly for most teens because its longer earbud playback and sweat- and water-resistance details make it the more practical listening-focused option. Tuanzi JM03 is the more interesting pick for teens who genuinely want a smartwatch’s alerts and activity records, and who are comfortable with shorter earbud sessions. For an open ear headphones gift for teens, I would first confirm that an in-ear style suits the recipient; neither model is described as open-ear. My recommendation for teens who mainly want earbuds is Spracht.
Spracht Zum Truly has the longer stated music playback: up to 14 hours. Tuanzi’s earbuds are listed at about 2.5 hours of continuous playback, so they suit shorter listening stretches better.
The Tuanzi earbuds are not waterproof, and the product information says to wipe sweat off before placing them back in the case. The watch is described as life waterproof, but that description does not apply to the earbuds.
The listed functions include step, calorie, and mileage records, along with multiple sport modes. The product information does not clearly explain which features work independently or how records sync, so check those details if phone-free tracking is essential.
Choose Tuanzi JM03 if you want a touchscreen watch with activity features, alerts, and Bluetooth calling alongside earbuds. Choose Spracht if longer earbud playback, multipoint pairing, and the stated sweat resistance matter more than having a watch.
