Ten years ago I was interested in buying Bose noise cancelling headphones. Someone warned me that they had read somewhere on the internet that noise cancelling creates problems with your hearing.
At the time I couldn’t find anything on Google about this, but I still bought the headphones anyway.
Using the headphones the lingering thought of that statement bothered me. Using the headphones something didn’t feel right.
Flash forward to now, people are talking about this so I can’t find relevant info on this without the well (Google) being poisoned by armchair doctors.
I still feel noise cancelling is not healthy for ears.
