I got round to trying the velour pads on my HD 250 and . . . Dreadful
Just makes them sound ordinary with no particular character or anything that makes them recognizable as a great headphone
Went back and put on the ones they came with:

These bring back a warm rich deep bass and more detailed highs. It could be too much i think with the wrong amp..?
Not sure but what is interesting having taken the pads off is:
a, they have the white donut ring on the driver
b, the pads themselves have a thin cloth on the back off them and
c, the foam tucked (inside inbetween that cloth and the plastic ring) is really thick
So it seems there is a lot of foam inbetween the driver and ones ear. Im surprised at the level of detail and clarity but then again Im no foam engineer!
Makes me wonder what the naked driver sounds like
Its weird how much difference this particular type of material pad makes in that velours work magically for my 540's ?
I can see someone might sell their 250 not realizing how good it actually cane be
Reminds me once again how you really don't your headphone until you try with different pads / foams / amps etc etc
