The pads on the t400 tends to worn out after in a year or so; they become much thinner than brand new. The good thing is the the pleather seems to be intact. I replaced mine with the pads from the 940s. Very comfortable and also solves the heat issue i had with the pleather pads. Acoustic improvement, maybe some difference with the bass control, but that is purely subjective.
