Noise Cancelling Headphones.

It has been made plain to me, that I am even less competent in understanding the complexities of modern technology than I had thought; and that is saying something.

In my innocence, I have been trying to source a pair of noise cancelling headphones, in the mistaken notion that when you wore them, they cancelled external noises and created a haven of peaceful silence within.

What I had not appreciated, was the fact that they create an internal cacophony of their own, as you have to use them to play some sounds of your choosing.

Sounds like a regime for future hearing problems.
