it all depends on the sample he used, like @Koey mentioned.
It is possible to get the same effect through EQing alone but you might want to try to transpose your samples as well, pitch your kicks lower and your snares higher. As well as playing with the ADSR of those samples. hope that helps.
With the kick, it sounds like all the high frequencies have been cut
With the snare, it sounds the opposite, all the lows have been cut,and everything running thru Lo-fi plugins
