Bose's highly competent marketing and high prices lead many average consumers to believe that their products are high-quality. Friction can develop between people who've always heard that Bose products are great, and people who have explained many times what's wrong with them.

Despite falling for basically the same marketing but in different ways (e.g. Audio-Technica and Denon's wooden phones) within their hobby, they will often compromise every other aspect of a product (usability, comfort, etc) for perceived superiority in sound quality in comparison to mass-market-appeal products such as Bose in order to prove that they are not 'part of the herd'.
