sduibek,
This is very simple and I'm sure all head-fiers abide by this.
First off, to imply that person A loves "THE MUSIC" more so than person B who likes the look of a headphone is insane. The two have nothing to do with each other.
Second, I personally love the way speakers/headphones look from the inside in addition to how they were constructed, which often can be told in the way the way they look. Simply put, I think they are works of art and it takes an artist to create them. Further more, I tend to think it's normal to look at and admire that art. Not paying attention to the design/looks of headphones is, to me, the same as ignoring the meaning and beauty of a water colour painting only to judge that painting for how talented/accurate that artist is when he/she paints a certain shape. The design is part is a small part of a whole!
Part of what goes into speaker/headphone/audio design is how the finished product will look. Of course it doesn't matter how something looks when stacking it up against sound quality. That much is a given. How a headphone looks is just one result out of many.
Lets now talk about the wood. As much as I like the way speakers/headphones look and are constructed, I equally like it when those audio products are made from wood. It just adds to an already beautiful piece of art. If I am going to spend 400+ dollars on a headphone or piece of audio equipment, then I would think that I as well as the designers put at least some thought into the way the finished product looks. Lets say I were to choose between two headphones of equal sound quality, both having two very distinct looks. One looks like one of those moded CD3k's (w/ the purple heart wood), and the other looks like two plastic squares resting on the side of your head. Which one would you choose? Which one would I choose? Does is really matter to you? And does me picking the more asthetically pleasing headphone tell you at all about how much I love music??? NOPE!! Every damn material item you have in your house has been designed to be at least somewhat pleasing to the eye. If you have a nice looking, wooden book shelf...why did you choose the nice wooden shelf over an extrtemely boring, ugly one? After all, the only purpose of that shelf is to set things on, right? And also remember that sight and visuals are just 1 out of our 5 natural senses. And the sense of sight plays a big role in how we perceive certain things. I think it is very neat to have the products that make up what my hobby is look somewhat nice and pleasing to the eye. I like to sit back sometimes and admire my HD650's for their sleek design and silver colour. Is there something wrong with that? Does that say I chose the 650 simply because they are silver and sleek?? I think you know the answer.
In closing...
I think that you'll find (and this has been done many times before already) that if you make up a poll asking how high on their priority list do looks matter to a person when purchasing a headphone, you will discover that most if not all of us rate it last or second to last behind sound quality, cost, comfort, synergy, technical specs, and a few others. Try it and your view or assessment that a lot of head-fiers care more about looks than sound quality will be pleasantly shot down.
