Just my personal opinion, but I think you can see the drivers/can design from the original Bose in a number of headphones on the market - they all tend to sound the same to me: Bose, Beats, Monster, Sol, etc. Heck, I think they're all manufactured in the same Chinese factory. So yeah, given the same driver, the variances only add up to the housings, pads, and materials used to make them.
One might say that the headphone market consists of perhaps 75% cr*p that's more or less the same, except for packaging and endorsements.
Head-Fi is here to try distinguish between that heap and audiophile phones that truly offer a different/better sound. Once you start looking/listening to headphones like that, everything is different - driver manufacturer, materials, can design, pad design, headband design, cable design, etc., etc. Most people probably can't hear those differences, but once you become accustomed to listening to many different headphones, it gets obvious.
