The FlipBuds Pro have three microphones - one is taking in the voice of the speaker during a call, another is listening for external noise and isolating it, while the third is making sure the user’s voice isn’t accidentally muted.

This is all enabled by the QCC5151 Bluetooth chip which listens and filters environmental sounds, so the wind doesn’t get accidentally picked up, ruining the audio experience. Bluetooth 5.2 is available for connectivity and thanks to this chip the FlipBuds Pro also support aptX Adaptive Dynamic Codec Protocol.
