Alrite just got my DT440 from Jaben yesterday...just love it.

I found out that by removing the piece of plastic behind the driver, you can make it fully open back (standard is just the size of 50cent coin in midddle)

So to all DT440 owners do try it out and let me have your feedback? I have not spend enough time with it to verify the different, but i do realize in changes of a wider sound stage.
