If you want simple, lightweight wireless earbuds for jogging, choose Bloody M70; if you need earbuds built into a smartwatch with fitness features, choose Tuanzi GT55. The M70 is the more straightforward choice for listening on the move, while the GT55 combines audio with calls, activity tracking, and a wrist-worn display.
For jogging, I’d favor the M70 if the goal is simply to carry and use a pair of earbuds. Choose the GT55 if you also want a watch for workout data and everyday smart functions.
• Bloody M70 strength: compact true-wireless earbuds with a charging case and up to 22 hours of stated total playtime; trade-off: they are audio-focused, without the smartwatch features of the GT55.
• Tuanzi GT55 strength: a smartwatch with built-in TWS earbuds, sports modes, Bluetooth calling, and health-tracking features; trade-off: it is a larger, multi-function device rather than a simple earbud set.
• Bloody M70 fits: listeners who want a dedicated pair of wireless earbuds for jogging and everyday use.
• Tuanzi GT55 fits: shoppers who want earbuds and a fitness-oriented smartwatch together, and are comfortable using the Da Fit app.
The Bloody M70 is a conventional true-wireless earbud set: two in-ear earbuds, a mini charging case, and Bluetooth 5.0 connectivity. Its 6 mm hybrid diaphragm drivers are described as designed for deep bass, and the listed frequency range is 20 Hz–20 kHz. It also has touch media controls and sound isolation. Those details point to a simple listening-first design, rather than a wearable packed with notifications and fitness tools.
The stated playtime is up to 22 hours with the charging case, while the product information lists four hours of average battery life for the earbuds. The case charges the earbuds, and the listed charging time is 1.5 hours. For jogging, that makes the M70 the more focused option if you want to put on earbuds and leave the rest of your workout tools at home. It includes three sizes of sleeves, which gives you options for fitting the in-ear design.
How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.

The Tuanzi GT55 is a smartwatch with TWS earbuds stored in the watch. Its 2.01-inch touchscreen and 345 mAh battery sit alongside functions such as Bluetooth calling, music control, alarms, weather, and remote camera control. The watch is compatible with most iOS 9.0 and Android 4.4-or-higher smartphones, and it requires the Da Fit app for its functions.
For jogging, its appeal is the combination of earbuds and workout tools. The listed sports modes include running, alongside activities such as mountaineering, skiing, cycling, and basketball. The watch also offers activity tracking and heart-rate, blood-oxygen, and sleep monitoring. Those readings are for exercise reference, not medical use. The product information lists a one-meter water-resistance depth, while its description characterizes the earbuds as waterproof, sweatproof, and dustproof; that is not a reason to treat the whole watch as suitable for swimming.
The GT55 makes more sense for someone who wants a watch on the wrist as well as earbuds for listening, and who values having calls, activity data, and other tools in one device. I’d skip it if all you want is a straightforward pair of earbuds. At 160 g for the listed item weight, it is also a more substantial package than a dedicated earbud set. The data does not describe bone-conduction headphones, an ear clip, or rotatable ear cups, so those specific fit styles are not established features here.
• Best for a simple earbud setup for jogging → Bloody M70. It is a dedicated true-wireless earbud set with a charging case, rather than a watch-and-earbud combination.
• Best for a smartwatch with earbuds included → Tuanzi GT55. Its earbuds are stored in the watch, which also offers a touchscreen and smart functions.
• Best for stated total playtime → Bloody M70. Its listed total is up to 22 hours with the case; the GT55 description gives about five hours for a single earbud playback session.
• Best for workout tracking on your wrist → Tuanzi GT55. It includes multiple sports modes and activity, heart-rate, blood-oxygen, and sleep tracking.
• Best for Bluetooth calls from a watch → Tuanzi GT55. Its listed functions include answering and rejecting calls through the watch.
• Best for a compact, audio-first choice → Bloody M70. The product is centered on earbuds and a mini charging case, without the GT55’s smartwatch interface.
• Best if you want features such as weather, alarms, and remote camera control → Tuanzi GT55. These are among its supported watch functions, accessed after connecting to a phone and using Da Fit.
• Best for a specific ear-clip or bone-conduction fit → Neither based on the listed details. The M70 is described as in-ear, and the GT55’s bundled earbuds are not identified as either ear-clip or bone-conduction models.
The distinction matters for a phrase shoppers may use, such as “best with mic ear clip headphones for jogging.” The GT55 does list Bluetooth calling, but the earbuds are not specified as ear-clip headphones. Similarly, neither product is documented as the “best rotatable ear cups wireless headphones for jogging.” Neither is described as having rotatable ear cups. And if you are searching for “lightweight bone conduction headphones for jogging,” these two do not match that design based on the available product details.
My Verdict
I’d choose the Bloody M70 for jogging if my main goal were dedicated wireless earbuds with a stated 22 hours of total playtime using the case. It keeps the decision focused on listening and avoids paying attention to a watch interface I may not need.
FAQ
The M70 is the more straightforward choice if you want dedicated true-wireless earbuds. The GT55 adds a smartwatch, sports modes, activity tracking, and Bluetooth calling, so it suits someone who wants more than audio while jogging.
Yes. Running is listed among its sports modes, and the watch provides activity-tracking features. Its health data is for exercise reference and should not be treated as medical measurement.
The M70 is listed for up to 22 hours of total playtime with its charging case, and its product information lists four hours of average earbud battery life. The GT55 description says its earbuds provide about five hours of playback per single session.
Neither product is described that way. The Bloody M70 is identified as an in-ear earbud set; the GT55 includes TWS earbuds stored in a smartwatch, but the listed information does not specify an ear-clip or bone-conduction design.
