Our take on the GT66 smart watch TWS Bluetooth headset 2 in1 multi sport mode heart rate sleep monitoring

The GT66 is a budget smartwatch with a pair of true wireless earbuds built into the watch body. The watch has a 1.39-inch round touchscreen at 360x360, heart rate and blood oxygen tracking, sleep and calorie tracking, multi-sport modes and NFC, and it pairs over Bluetooth LE 5.2. The earbuds use Bluetooth 5.0, work with Android and iOS, and run about 5 hours per charge from a 30mAh cell. It suits someone who wants one charger and one device for workouts and calls, but the small earbud battery and generic app support put it behind established fitness watches on accuracy and ecosystem.
