Has Active Noise Cancellation (Noise Control)
Sony WF 1000XM4
✓
JBL Tour Pro 2 ✓
Active noise cancellation uses more advanced technology to reduce unwanted ambient sounds. How it works, it listens to the sound pattern outside and inside the earbud and after inverts the soundwaves to cancel it out. Simply put, it's like taking +1 (sound from your surrounding) then adding -1 (inverted noise) to make 0 hence "diluting" the noise.
The JBL Tour Pro 2 have ANC allowing you to listen at lower levels of volume, causing less ear fatigue since you don't have to crank up the earbuds volume to overcome background sounds.
The Sony WF 1000XM4 too have ANC which makes both earbuds ideal for plane rides and rush hour travels. Each work with different noise cancellation modes, pick the setting that suits your travel or that enhances your relaxation time.
