I am on headphiles.org. So you can point me the threads you saw the woods from. There are 2 wood makers currently in the loop - 1 is PrawnCracker which makes 'em from mahogany wood, and Kerwinsee that uses ironwood.
If i am to convert price, the woods will be less S$100 a pair.
Headbands are also available. DIYed leather goodness. You can choose what type of leather you want too, depends on availability.
