How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a wearable that doubles as your workout companion and keeps your phone out of the equation, choose Tuanzi GT100; if you need earbuds built for clear calls and all-day office work, choose Accutone Walker 30.
• Tuanzi GT100's biggest strength: It fuses a 1.43-inch 466x466 smartwatch with hidden TWS earbuds, and the watch itself plays local MP3s, tracks heart rate, blood pressure and SpO2, and handles Bluetooth calls — all in one IP67 shell.
• Tuanzi GT100's biggest trade-off: The earbuds deliver roughly 5 hours of play per charge and the design leans heavily on the watch side of the equation, so it's not a dedicated audio-first product.
• Accutone Walker 30's biggest strength: It's a purpose-built business headset with dual-mic ANC, a UAC dongle for Bluetooth-less desktops, native Teams controls, and up to 30 hours of extra case charge.
• Accutone Walker 30's biggest trade-off: It has no smartwatch functions, no local music storage, and its 10mm drivers are tuned for bass rather than flat reference listening.
• Pick Tuanzi GT100 if you want one device that covers fitness tracking, calls and casual listening on the move.
• Pick Accutone Walker 30 if you live in video meetings and need reliable mic clarity plus desktop connectivity.
The GT100 is best understood as a smartwatch that happens to have earbuds hidden inside it. The 1.43-inch IPS display runs at 466x466, which is genuinely sharp for a round watch face, and the software supports eight UI styles plus a long list of languages. Raise-to-wake works, weather syncs, and you get the usual fitness staples: calories, steps, sleep, heart rate, blood pressure and SpO2, all fed through what Tuanzi calls an innovative algorithm chip. Rounding it out are camera remote control, recording, Siri, alarms and app notifications from Gmail, Facebook, WhatsApp-adjacent services and more.
The earbuds themselves are graphene-built, sweat-resistant, and designed with a hidden charging-thimble shield so sweat doesn't corrode the contacts during training. A single play session runs about 5 hours. The nano chip handles dual-mode Bluetooth calling, so you can answer from the watch or from the buds and switch between them — that's a genuinely useful trick when your hands are busy mid-workout.
Who should skip it: if you want audiophile tuning, long solo listening sessions, or a headset that anchors your workday video calls, this isn't that product. The earbuds are a companion feature, not the main event.
Accutone Walker 30: Who It's For
The Walker 30 is aimed squarely at people who spend their day on Microsoft Teams and Zoom. Dual-microphone active noise cancelling handles voice reception by sampling background noise and cancelling it against your voice, with the system blocking up to 26dB of ambient sound. There's a one-key activation for super-quiet listening, and the company describes it as a hybrid system — ENC for the mic, ANC for the speaker.
The standout feature is the UAC dongle. Plenty of office desktops have no Bluetooth at all; plug the dongle in and the Walker 30 converts the wireless connection into USB audio. That also unlocks native MS Teams controls on desktops and laptops, not just phones. It's a small thing that removes a real daily annoyance.
Day to day, the buds run up to 6 hours per charge with 30 more hours stored in the case, which itself supports Qi wireless charging — drop the case on any wireless pad and forget about cables. Bluetooth 5.3 covers a 10-meter range, and IPX5 means light drizzle won't kill them. The pair of 10mm dynamic drivers are explicitly tuned for bass, so music sounds full rather than clinical. Touch controls handle playback and Siri, and the package includes a user manual and wireless charging case in a giftbox.
Who should buy it: hybrid and office workers, remote staff on constant calls, and anyone whose desk setup lacks Bluetooth. Who should skip it: athletes who want in-ear buds that survive heavy sweat, and buyers who want health tracking or standalone music storage.
• Best for fitness tracking → Tuanzi GT100. Heart rate, blood pressure, SpO2, sleep and steps are all built in; the Walker 30 tracks nothing.
• Best for video meetings → Accutone Walker 30. Dual-mic ANC, 26dB noise blocking and Teams controls are purpose-built for calls.
• Best for battery endurance → Accutone Walker 30. 6 hours per charge plus 30 hours in the case beats the GT100's roughly 5-hour earbud sessions.
• Best for leaving your phone behind → Tuanzi GT100. The 128MB player stores 30 to 50 songs for phone-free runs.
• Best for desktop setups without Bluetooth → Accutone Walker 30. The UAC dongle converts the connection to USB audio.
• Best for rugged outdoor use → Tuanzi GT100. IP67, sweat-proofing and shock/drop resistance outrank the Walker 30's IPX5 splash rating.
• Best for charging convenience → Accutone Walker 30. Qi wireless charging on the case is genuinely cable-free.
• Best all-in-one gadget → Tuanzi GT100. Watch, earbuds, calls and music in a single 240g package.
If I had to pick one, I'd take the Accutone Walker 30. In my opinion, it does one job properly: it makes you sound clear on calls, works on desktops without Bluetooth, and its 36-hour combined battery story is easy to live with. The Tuanzi GT100 is clever and fun, and I'd happily recommend it to a runner who wants music without a phone — but its earbuds are a bonus feature, not the reason to buy. Buy the Walker 30 for work; buy the GT100 for the gym.
how to pair tws headphones
Take both earbuds out of the case and they normally enter pairing mode automatically. On your phone, open Bluetooth settings, wait for the model name to appear, and tap it to connect. On the Tuanzi GT100 you can also pair through the watch; on the Walker 30, the UAC dongle pairs the same way for desktops.
how to connect tws headphones
Once paired, connection is automatic whenever you remove the buds from the case and Bluetooth is on nearby. The Walker 30 adds a second path: plug the UAC dongle into a computer and it connects as USB audio without any Bluetooth at all. The GT100 connects through a single simple Bluetooth link that also carries calls.
how to use tws headphones
Tap or double-tap the touch controls to play, pause and answer calls — the GT100 uses double-click for answer/hang-up and triple-click on each bud for track skipping. The Walker 30 uses touch controls plus one-key ANC activation, and supports Siri. Both handle volume and calls from the buds themselves.
how to reset tws headphones
Most TWS buds reset by holding the touch area for several seconds until the indicator flashes, then re-pairing from scratch. If that fails, clear the old entry from your phone's Bluetooth list first. For the GT100, restart the watch as well so the dual-call link re-establishes cleanly.
