Can you change sound modes on Liberty Air 2?

Looking to see if you can make a noise canceling mode and or ambient.

I gave some to my mother in law but she probably does not use the reduction part.

I think it is a tap on the bud for a noise reduction as they called it. I do not think they had the ambient mode. Beside the Life NC that came out before these, it was probably one of the first with the noise reduction.

I believe that they were one of the more popular set when it came out. I do know there is about 3 iteration out there with different button controls (single tap, double tap, or single/double tap, If I remember right)
