What is the difference between Sound Isolating & Noise Cancelling?
The seal created by a sound isolating earphone physically blocks most frequencies of background noise. Active noise cancellation “headphones” are generally larger, heavier and battery-driven. The active cancellation process negates selected frequencies through a complex process that can even introduce unwanted artifacts into the resulting audio. The natural sound isolation properties of a properly fitted in ear earphone exceeds the performance of even the most expensive active noise cancellation alternatives.
