Thank you for all your replies, I'll try to address the biggest suggestions here:
I have the PTH device, but I feel REALLY awkward talking to people, especially my manager with earphones in, I think it's a respect thing and I want to give them my full attention (and i want them to know I'm not distracted talking to them)
I tried the AD700 for a little bit, still had the same issue as the M50, eardrums got sore. not to mention the thing creaks.
Just got the AD900 today, LOVE IT. doing the burn in right now. Already my eardrums are happier than with the AD700 (maybe its a angled driver thing?). I just hope the sound bleed isnt bad at the office with low listening levels. It seems like i love the sound of open-backs, but perhaps i will resume my search for a closed headphone later down the road.
The reason why I wanted to try stick to the audio technicas, was because i like the headphone style (the double wire on top, no adjusting necessary). I'm not a fan of the folding and adjusting headphones.
I did try the SRH840, the M50 was just more comfortable at the store. I wish I would have taken it home though instead of the M50.
So, I would like to ask you all. What is a good amp to pair with an iPhone 4S w/ sendstation dock dongle, and the AD900?
I've been looking into tubes, and i don't know if thats something i want.(i want warm sound, lots of depth, easy on the ears)
edit: after 4ish hours of burn-in (switching between pink-noise and various kinds of music) the highs have really mellowed out. WOW these are amazing. Gonna keep playing rotations of music and pink noise overnight and take these to work in the morning. I think the AD900's are a winner.
