The Amazfit ZenBuds are specifically designed for plugging into your ears and blocking out outdoor noise. Besides helping you unwind, the snug fit is designed to help you sleep more peacefully. The ZenBuds come with soothing sounds built-in that help you rest and fall asleep easily. They are also equipped with sleep tracking sensors and these turn the relaxing sounds automatically when you fall asleep. Besides the sleep trackers, the Amazfit ZenBuds also feature support for heart rate monitoring and provide you with sleep data as well as suggestions for better sleep within the companion Amazfit app.
