With some EQ you can tame the bass, if you feel the mids are too thick at default.
I wouldn't say the bass is bleeding in the mids, but the bass is quite strong.
Boomy usually means that the 100Hz - 250Hz area is a bit too enhanced, thing which can be fixed by the way I EQ 99C and 99N:
31 Hz + 3dB
62 Hz + 1dB
125 Hz 0 dB
250 Hz -3 dB
500 Hz + 3 dB
1 kHz + 3 dB
2 kHz + 3 dB
4 kHz + 3 dB
8 kHz + 0 dB
16 kHz + 18 dB
You should consider that those are quite smooth by default though, so you shouldn't have issues with the treble and such, but the bass is quite strong.
Another thing I'd like to notice is that the extreme EQ above will cause some strange shifts in the FR, so not only the treble will be changed by adding that much treble, but also the bass will change.
If you don't EQ them at all, the bass is nice, I enjoy it, but the top end is smooth, which I prefer to be a tad more energetic, especially for metal and upbeat music
