I. S.
It's a little bit thicker than the XM5's cushions, just a bit, but combined with the MUCH better foam it makes for a much better fit and slight improvement to sound. An unexpected improvement is that with the original cushions, any slight bump would impact the ANC, with these, it seems it can resist a bit more before the ANC has to calibrate. Overall, really pleased.
