Huawei FreeBuds are wireless Bluetooth and NearLink earbuds. They were first announced and released on March 27, 2018, alongside Huawei P20 series. In addition to playing audio, the Huawei FreeBuds contains a microphone that filters out background noises as well as built-in accelerometers and optical sensors capable to detect taps and pinches (e.g. double-tap or pinch to pause audio) and placement within the ear, which enables automatic pausing of audio when they are taken out of the ear.
