When I first burned in my DT 770's (32ohm) overnight they sounded much better, with way more bass than before burn in. I loved the deep, detailed, punchy bass. Now after about a week later with regular listening and sometimes pink noise burn in I'm noticing that the bass is weak. Is my mind playing tricks on me or did they actually lose bass after extended burn in?

There was a loss of bass. This may self correct with more use with music, but I suspect this indicates a need for better amplification. What equipment are you plugging into?

I've noticed this before with two headphones. The first time it was with my DJ100. They had a lot of bass out of the box and then it got reduced after burn-in. My k240 was also fairly bass heavy right out of the box and even had a large mid-bass hump it seemed like. Now they're just fine and the bass has gotten tamed a bit. Each time though I used a good amp.

Bass is weak? Please describe how the bass and/or bass lines sound with your favourite bassy tracks in your own words. Maybe the DT770 is less bass emphasized than you think?
 
Give it some time otherwise the DT770-32 is not what you were looking for.

teh voice coil is loosening up so teh bass will be less impactful but should behave more body is what ive experienced

I have the same feelings. I was thinking probably I've got accustomed to it as opposed to the first expression.

Hah, you won't believe this but out of curiosity I randomly turned off my fan that has been running nearly constantly for the past couple of days and noticed that the bass is stronger. So the weak bass that I've been noticing seems to be just because of background noise. I am running them out of an Audigy2ZS.

This is what I'm looking for, Thanks for your analysis!
