Headphones which accurately represent the original mix of the music clearly and evenly at the broadest frequency range. They are balanced and represent the sound the same way regardless of volume.So, when someone says, 'I want headphones with really good bass,' you can tell that they probably don't know much about headphones and you will probably be able to sell them a pair of Dre Beats. They have 'good bass' that is actually not so good.
This PhD has ruined my life. I want headphones, so I formed a research question, did a literature review, did some data collection, and then made a decision about what I would buy. I swear to god, I'm not a Positivist. I'm a Pragmatist--a William James Pragmatist, not a Barack Obama pragmatist--who trusts procedural objectivity.
This accuracy bit is really a new thought to me. Good headphones let you hear the way the song was actually mixed (i.e., the way the artist has, in theory, wanted you to hear it) and if you have a headphone that skews towards the DJ smile (high lows and high highs with a depressed middle), you reinterpret the sound, perhaps to your preference, perhaps not. If you are listening to a Fleet Foxes song, you don't want to have overpowering bass: you want to hear it clearly in balance to the amazing harmonies that are happening across the frequency scale. Worse, if you enjoy some Biggie every now and then, the bass is so pronounced in the mix already that if you put on a headphone that represents the bass too powerfully, you get an unpleasant experience full of distortion. You want Biggie to kick down the door, but you don't want him to kick it down in a way that injures the person on the other side.
This is an extended metaphor: is it a story or a scenario? I suppose it's a story: it has two events--Biggie kicks down the door and injures someone.
I've always thought of Bose headphones as the best, but they aren't: they are the best for a particular category of people who have money. They want something they describe as a great headphone: comfortable and which makes the music they listen to sound good, along with a bunch of other criteria that have nothing to do with sound (portability, isolation, style).
Emic words describe the world of particular experience, not exact, precise, replicable things. The Positivist throws out the emic terms: they aren't reliable, they differ so much among people. The Positivist, however, sells no headphones because those emic terms determine who buys what. The world is a complicated place, it turns out: much more often unreliable.
For me, portability, durability, price, and isolation are also important criteria, but again, they are different questions than the sound of the headphone. I also want a headphone that's classic, not stylish. The Beats look 'great' today (if 'great' is whatever everyone else is into at the moment), break tomorrow. I also want ones that aren't going to fall apart in two years, right after the manufacturer warranty is up. And I want good sound at low levels on the underground and none of this sound-cancelling apparatus crap (who wants to carry around AAA batteries anyway). I want them to sound good at work, walking to Middlesex, on the train, and on the underground.
Now, to convince myself that they're actually worth it and I can justify the cost to myself.
