active noise reduction means a chip analyzes incoming frequencies and emit the same one back to cancel it out before it reaches your ear.

There is indeed a noticeable difference in noise level, with active noise reduction being slightly better.

However, there are situations where the active noise reduction gadget doesn’t work so well, such as when there are many frequencies or when frequencies shift often and irregularly.
