ANC uses advanced technology to reduce ambient sounds. How it works, it detects and analyzes the sound pattern of incoming noise and then generates a mirror signal to counter it. Simply put, it's like taking +1 (noise) and producing -1 (inverted noise) to make 0 which results in a reduced level of noise.
The Beats Studio Buds have Active Noise Cancellation enabling you to listen at lower levels of volume, good for your ears as you don't need to crank up the device volume to overcome background noise.
Sony WF 1000XM4 too have ANC making both devices ideal for plane rides and rush hour commutes. Each operate with different noise cancellation modes, pick the setting that suits your travel or that enhances your chill time.
