So pretentious.
I don't ask people for their IQ score before I spend time with them, but this has held true across the entire cross-section of society that I've personally experienced. When I was working as a dishwasher, everyone would bring small Bluetooth speakers to their area if they wanted to listen to music.
Do you think that people with a certain background / IQ score are not enlightened enough to recognize tinniness or poor sound quality?
