All headphones offer a certain amount of isolation from noise. This is not the result of technology, but of the headphones’ design. The ear tips in the in-ear earbuds seal the ears at different levels, excluding some of the ambient noise. We call this “Passive Noise Cancelling”, as there is no technology involved. 

When the earbuds feature a technology to actively block external noises, we can talk about earbuds with “Active Noise Cancelling”. The JBL wireless earbuds feature three types of Active Noise Cancelling technology. Depending on your needs, you can choose the one that suits you best.
