I understand the exchange of critical information requested about an important purchase so hope I'm not being a killjoy if I ask why, when we are all exhorted to be in the moment and alert to everything in the world around us, would anyone want to block out sounds around them - for enjoyment or safety? Is this a luxury for some societies today?
My husband wanted to be completely immersed in any music he listened to without the distraction of any other activity, although I have to admit as a much younger person I did turn up my car stereo which probably served to distract me off from some dangers.
