Since I bit the bullet and pre-ordered the T1s, I now have a vested interest in the product, so...
It looks like Beyerdynamic have improved the comfort of their headband design and are currently offering a (free?) exchange of old for new - http://www.head-fi.org/forum/thread/542487/beyerdynamic-t1-s-headband-exchange
Is the stock you are getting the old or new design...and if the former, how do we go about taking advantage of this new comfort-enhancing offer?Edit
: Don't mind me - I just checked the date of the original post and had a 'duh' moment.
