Product Description
Monitor your heart rate as you work out with the PowerBuds True Wireless In-Ear Sport Headphones from Amazfit. PPG sensors in the earbuds provide heart rate monitor as you exercise. Set a heart rate limit in the Amazfit mobile app and the PowerBuds will give you voice notifications when you push yourself too hard. The PowerBuds sport headphones can handle even the toughest workouts with IP55-rated sweat and water resistance, and magnetic ear hooks that keep them in place.
Your favorite music and podcasts are pumped through 9mm drivers with a composite diaphragm. The PowerBuds can play audio continuously for up to 8 hours on a full charge. Snap them into the included charging case for an additional 16 hours of power. As you listen, you can engage Motion Beat mode to boost the bass or Thru Mode to increase the volume of ambient noise, such as traffic or announcements.
