Came across this set of review and it's been a great help! I'm currently looking between the HFi-780s and the ATH M50s for a more travel-oriented usage.
Similar to the review, I don't expect an amp, but comfort is much more important to me. I don't care as much for bass, but all of the raving I have heard surrounding the 780's treble makes me very interested.
Considering this would be my entry into headphones outside of crummy $10 pairs, would the difference in sound make enough of a difference in the HFi 780s over the M50, or are the Ultrasones really so uncomfortable that I wouldn't be able to enjoy them during travel as much as I would the M50s? I may even use the minor sock mod to add a little comfort for the Audio Technicas. I can find them both right now for $155 new.
Hfi 780 and m50 are very different headphones. I find 780 to be a bit harsh and grating in the treble. It's too much detail IMO lol. M50s are much warmer than hfi 780. Hfi 580, though, are warmer than the 780 and have more bass, but a bit less detail overall. Hfi 580
are better than m50 IMO, but a bit less comfortable. You're choice
