Upgraded from DT1770 to T5 Gen3. Happy! Like night and day! These drivers are amazing, with EQ you can do kind of everything. Note, if standart softskin pads will be replaced to velour (as I did, took them from DT1770) - low end will be rolled off. But again, as drivers are very capable, just with EQ we can "fix" this. Im using ADI-2 DAC FS and LG V60. On both need to add from 5 to 7 dB on low end.
+1 on the EQ.
With only minor tweaks...these issues being mentioned can be cleared up with ease, leaving a super resolving headphones with impact and great soundstage.
I used to think using EQ was besides the point of getting high end gear....but there is no perfect headphone for me, only close enough. EQ fixes that.
