Xiaomi has introduced a new product called the True Wireless Noise Cancelling Headphones 3 Pro today (September 27, 2021). This lengthy title covers a lot of what these new AirPod clones offer, although there is even more besides. They include IP55 ingress protection, up to 33 hours of use between charges and a new audio codec for "HiFi" sound.
