Going deaf full spectrum is exactly what I am after!
I have personally tried out the Sennheiser HD25's and although they sounded good, and felt okay at first, after about 45 minutes my ears started getting a bit sore so those are definitely a no-go for me. As for the Beyerdynamic DT 770 Pro's - I don't believe I have had a chance to try them on, but I have read some good reviews so I think I may have to go down to the store and see if they have one on display. A buddy of mine recomended the Audio Technica ATH-M70X's here - from what I've read it seems like they get great reviews pretty much only for personal music listening, though so I'm not really sure what to think - Do you have any experience with those? Would you still go with the Beyerdynamic's over Audio Technica? They're pretty much in the same price range it looks like, though my local shop I can probably get the M70X's for about 40$ off list price.
Thanks again for your time.
