The FreeBuds Pro are true wireless stereo (TWS) in-ear earbuds and come with a charging case. Mermaid earbuds feature active noise cancelation (ANC), which can be activated when making voice calls or playing music. The advanced triple-microphone acoustic design combines an 11 mm-diameter dynamic driver, feedforward plus feedback (FF+FB) noise reduction, and audio transparency, and result is crystal clear sound during voice calls. Mermaid earbuds use little power and come with a charging case, so you can enjoy a long battery life. Adopting the Hybrid Active Noise Cancellation Technology, the inward-facing and outward-facing microphones detect the out-of-ear and in-ear residual noise, and then the dynamic drivers generate accurate anti-noise signals. Achieving up to 40 dB noise cancelling effect, HUAWEI FreeBuds Pro allows you to experience the tranquility and purity. No need to take off your earbuds. Just a long press, you can switch to awareness mode and reconnect with your surroundings. The unique Voice Mode reduces the ambient sounds to make human voices stand out. So you don’t miss the airport broadcasts or a quick chat with friends passing-by. The highly sensitive sensor responds accurately to your demands. With swipe, press or pinch, you can turn up or down the volume, take calls, or change your music easily. Smart interactions, easy to control. Headphone FeaturesSilicon ear pieces.
