The Huawei FreeBuds Pro detect ambient sounds and intelligently adjust noise cancellation to enhance your listening experience. You don't need to take the FreeBuds Pro out; a long press is enough to switch to awareness mode and interact with your surroundings again. The unique voice mode reduces background noise to highlight human voices, allowing you to follow announcements at the airport and chat with friends you meet along the way. With noise cancellation turned off, you can listen to music for up to 7 hours on a single charge, and with the charging case, up to 30 hours. You can also use your smartphone or tablet on the go to charge the charging case.
