I guess the main problem is that audiophiles either don't care that much about what they look like in the public or don't mind suffering (head clamping force, bulkyness...) to achieve better audio quality.Personally I don't see why so many so-called audiophiles or headphonophiles have such a problem with the Triports.
Besides, most people don't need closed headphones. IEMs and open headphones do the trick for most people. And there are many alternatives in these categories that can rival the TriPorts' sound quality with a lot cheaper price.
But in the closed heaphones that are good-looking, comfortable and portable -category, there isn't that much choice.
