Much of music is created with instruments made from natural wood from a finely tuned Steinway piano or Stradivarius violin to classic Fender Stratocaster guitars. The low resonance characteristics of wood provide for efficient, clean, rich reproduction of music which is why all of the most high end home speakers are made of wood. Simply tap on something metal or plastic and then tap on something made of wood, and you will instantly hear the resonance differences between those materials. So, it is only "natural" to create quality earphones from wood. Woodees!
