The Huawei FreeBuds Pro Wireless Bluetooth Noise-Cancelling Earphones have intelligent active noise-cancelling, so you can enjoy your music without distractions. The buds detect and filter our background noise for the best experience, so you can block out chatter when you're in a café, or cut background hum on buses or planes. There's no need to take out your earbuds to have a conversation. Voice mode reduces ambient sounds to make voices stand out, so you won't miss your departure annoucement.
