Has Active Noise Cancellation (Noise Control)
Jabra Elite 7 Pro

JBL Live Free 2 ✓
Active noise cancellation makes use of 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. In simple terms, it's like having +1 (sound from your surrounding) then producing -1 (counter sound by the device) giving zero thus "diluting" the noise.
The Jabra Elite 7 Pro have ANC allowing you to listen at lower volume levels, good for your ears since you don't need to crank up the earbuds volume to overcome background noise.
JBL Live Free 2 too have Active Noise Cancellation which makes either of the devices ideal for flights and rush hour commutes. Each work with different noise cancellation settings, pick the mode that you prefer for commute or that enhances your relaxation time.
