I have always put up with loud and busy environments, because of not knowing the reason and now that I do, next year, my faith is starting in person conventions and one day assemblies next year and the convention is 3 days worth. My husband suggested I use my descreet headphones and play some of our amazing spiritual music, but after thinking about it, it could be misjudged as inappropriate, due to the occasion, so I figure I should use obvious noise cancelling phones, but I hate silence and so, I need to know if it just lessons sound and a cheap, but affective pair?
