Has Active Noise Cancellation (Noise Control)

JBL Live Free 2 ✓
Active noise cancellation uses more advanced technology to reduce ambient sounds. How it works, it studies the sound pattern outside and inside the earbud and after inverts the soundwaves to counter it. Simply put, it's like having +1 (noise) and producing -1 (counter sound by the device) giving zero thus "diluting" the noise.
The OnePlus Buds Z2 have ANC allowing you to listen at lower volume levels, causing less ear fatigue as you don't have to crank up the device volume to overcome background sounds.
JBL Live Free 2 too have ANC which makes either of the devices ideal for flights and rush hour commutes. Each operate with different noise cancellation settings, pick the mode that suits your travel or that suites your relaxation time.
