I add T70/T70's micro velour pads to the list.
Those are nice pads for those who like velour touch, sound is good, but tad sounds like T70s.
And official velour pads for T1(EDT990VB) won't make sense for T5p because those are made for open back headphones (T1, DT990, DT880),
and will result significant reduction of amount of bass.
EDT770 series (EDT770S, EDT770V, EDT770VB) for closed back headphones are nice match for T5p.
