• Tuanzi GT100 biggest strength: it's a two-in-one product — a 1.43-inch round smartwatch with hidden TWS earbuds inside, plus health monitoring, a 128MB music player and IP67 protection.
• Tuanzi GT100 biggest trade-off: it's a hybrid, so neither half is as specialized as a dedicated watch or a dedicated pair of earbuds. It also weighs 240 g, which you'll notice on your wrist.
• Xmenha Touch Screen Earbuds biggest strength: an open-ear, ear-hook design aimed at small ear canals, with a touchscreen charging case that handles volume, sound modes, battery readouts, time and alarms.
• Xmenha Touch Screen Earbuds biggest trade-off: it's earbuds only — no watch, no health sensors, no on-board music storage. Everything runs through Bluetooth 5.4 and your phone.
• Who each pick is for: the Tuanzi GT100 suits someone who wants one gadget for fitness tracking, calls and music. The Xmenha Touch Screen Earbuds suit someone who mainly wants comfortable, stable earbuds for running and gym sessions and likes the idea of a smart case.
The GT100 is a genuinely unusual product. It's a round smartwatch with a 1.43-inch IPS full-touch display at 466x466 resolution, and the TWS earbuds live inside it. That single design decision shapes everything else. You get a watch on your wrist and headphones on demand, with no separate case to carry and no second device to charge. For someone who commutes, trains and takes calls, that consolidation is the whole appeal.
The specs back up the fitness angle. It's IP67 rated with 1 metre of water resistance, and Tuanzi describes it as waterproof, sweat-proof and dust-proof — the earbuds even have a hidden sweat-proof design meant to keep sweat away from the charging pins. On the health side there's heart rate, blood pressure, blood oxygen and sleep monitoring through a dedicated algorithm chip, plus a long list of sport modes. The 400mAh battery is rated for around 15 days of average life and about 3 hours to charge. Each earbud gives roughly 5 hours of play time, and the graphene drivers are the basis for the sound.
The extras are where it gets interesting for a specific buyer. There's 128MB of player memory, which Tuanzi says stores roughly 30-50 songs, plus local music playback and recording. That means you can leave your phone behind on a run and still have music. Bluetooth calling works through the watch and the earbuds, with double-click to answer or hang up, and a simple tap pattern for track skipping. You also get weather sync, raise-to-wake, alarms, a camera remote, Siri support and notifications from apps like Gmail, Facebook, LINE and WeChat. The band is silicone at 20mm wide and 26cm long, the case is aluminium, and the screen supports a range of UI styles and languages.
Who should buy it: anyone who wants a fitness watch and wireless earbuds in one package, values on-board music storage, and doesn't mind a larger, heavier watch. Who should skip it: anyone who wants featherweight earbuds, a slim everyday watch, or a dedicated audio product first and foremost. If audio quality is your top priority, a purpose-built pair of earbuds will usually serve you better.
The Xmenha earbuds solve a narrower but very real problem: finding earbuds that actually fit small ears and stay put. The design is open-ear with ear hooks and wings, and the earpieces are described as smaller and lighter than typical TWS buds, made from soft silicone. Rather than plugging deep into the ear canal, they rest in place — which is exactly what people with small or sensitive ears tend to look for.
The standout feature is the charging case. It has a touchscreen that lets you adjust volume, switch sound effect modes, check battery levels for both the buds and the case, see the time, and set alarms — all without pulling out your phone. If you've ever fumbled with a phone mid-run just to change the volume, that's the use case this is built around. It's a small thing that changes how the product feels day to day.
On audio, Xmenha cites patented speaker and acoustic cavity technology with a "whale cavity" stereo surround effect, plus reduced sound leakage for privacy. The driver is a dynamic type with a 20Hz-20,000Hz frequency range, and there's a built-in microphone with noise control and sound isolation for calls. Bluetooth is version 5.4 with roughly 10 metres of range. Charging is USB-C, and the battery is 400mAh with up to 30 hours of total listening and about 5 hours per charge. Sweatproofing is described as professional-grade for daily sweat and rain, and the ear-hook design is aimed at staying stable through running and jumping. Colour options are black and white.
Who should buy it: runners, gym-goers and anyone with small ear canals who wants open-ear comfort, a stable fit and case-side controls. Who should skip it: anyone who wants a watch, health tracking or offline music storage, or who prefers a traditional in-ear seal for maximum isolation. The open-ear fit trades some passive blocking for comfort and awareness.
• Best for fitness tracking and health monitoring → Tuanzi GT100. Heart rate, blood pressure, blood oxygen and sleep tracking are all built in; the Xmenha has none.
• Best for small ears and open-ear comfort → Xmenha Touch Screen Earbuds. The ear-hook, silicone, no-deep-insertion design is the entire point of the product.
• Best for listening without your phone → Tuanzi GT100. The 128MB player stores around 30-50 songs for local playback; the Xmenha relies on your phone over Bluetooth.
• Best for case-side controls → Xmenha Touch Screen Earbuds. Volume, sound modes, battery levels, time and alarms all sit on the charging case screen.
• Best for total listening time → Xmenha Touch Screen Earbuds. Up to 30 hours combined versus roughly 5 hours per earbud on the Tuanzi.
• Best for calls from your wrist → Tuanzi GT100. The watch can pull up a number and answer, and calls switch between watch and earbuds.
• Best for carrying less → Tuanzi GT100. One item on your wrist replaces a watch plus a separate earbud case.
• Best for lighter, more specialized audio → Xmenha Touch Screen Earbuds. Bluetooth 5.4, dynamic drivers and a 20Hz-20,000Hz range in a purpose-built earbud.
In my opinion, the Tuanzi GT100 is the more useful buy for most people, simply because it does two jobs in one device and adds health tracking, offline music and IP67 durability on top. If you want a fitness companion that covers your wrist and your ears at once, that's the pick. I'd only steer you to the Xmenha Touch Screen Earbuds if small-ear comfort and open-ear stability matter more to you than anything else — in that case the ear-hook fit and the smart charging case are genuinely compelling. Check the current price on Amazon before deciding, since that's the one factor that could tip a close call either way.
how to connect tws headphones
Open your phone's Bluetooth settings, turn the earbuds on and put them in pairing mode, then select them from the list of available devices. With the Tuanzi GT100, Tuanzi describes a single simple Bluetooth connection that links the watch and earbuds together. With the Xmenha earbuds, you pair them as standard Bluetooth 5.4 devices within roughly 10 metres.
how to pair tws headphones
Pairing is the same first-time step as connecting: enable Bluetooth on your phone, power on the buds, and choose them from the device list. The Xmenha earbuds ship with a user manual, and Xmenha advises reading it before use — worth doing, since the ear-hook design and touch controls have their own quirks. Once paired, most phones reconnect automatically the next time you take them out.
how to use tws headphones
On the Tuanzi GT100, double-click to answer or hang up and play or pause, tap the left earbud three times for the previous track and the right earbud three times for the next one. On the Xmenha earbuds, control is touch-based, and you can also adjust volume, sound modes and alarms directly on the charging case screen. Both support calls through a built-in microphone.
how to reset tws headphones
A reset usually means clearing the pairing memory and starting fresh — typically by holding the touch area or button until the indicator flashes, then re-pairing from your phone. The exact sequence differs by model, so follow the manual that comes with your earbuds. If you're resetting the Tuanzi GT100, remember the watch and earbuds are linked, so re-establish the Bluetooth connection between them as well.
