Heard by whom?
The usual trouble with gear rumors is that:
- many pieces of gear are simply a matter of personal taste / preference
- missing ways or methods to validate a rumour (not necessarily the case on your side)
- no clear thought about adequate usage of a specific piece of gear (dito, reg. your side)
My personal experience with studio headphones:
- wearability, durability and reliability / consistency in performance -> main, objective criteria
- compromise of money value vs. function and performance -> subjective criteria, personal decision
32 Ohms with studio headphones without - in that case inadequately - an extra headphone amp usually would be such a compromise, if you could otherwise easily use 250 Ohms or higher.
Whoever thinks that studio headphones generally won't do the job at 32 Ohms (or at an even lower impedance), should FIRST do their own A-B comparison, if possible, before giving any final judgement on a specific earphone's electro-acoustic (and musical) quality.
Some people won't be satisfied with such a compromise, others might still be delighted by the subtle and well defined impulse of that beyerdynamic 770/880/990 series.
Personally, I'm pretty much used to working with half-open AKGs (beginning with a K500 around 1992), and I've been using them for over two decades for my studio work AND listening pleasure.
Now for a while I've been using many brands and kinds, and the 250 Ohms DT-770 Pro, and they're so damn close to the neutral and "honest" sound of my studio monitors, that I'd even buy a pair of 770s in 32 Ohms.
Just for the fun of it, since, by long-term experience, I tend to trust that company as far as things can get.
Although - for mobile purposes - I'd probably have to get one of those battery driven pocket headphone amps in addition, which might help a bit.
 my apologies, initially misspelled your nick and corrected it.
 grammar. Argh!
