Funny that something similar swore me off another brand’s headphones. The noise cancelling would amplify mechanical vibrations of the headphones, so much so that even eating with them on would cause a deafening bass. Walking with them on was also incredibly loud.
I sent them to support with a very good description of the problem, came back the same, “cannot reproduce”.
It seems support workers for both companies just connect them to an audio source and check if sound comes out relatively alright.
