Bass heavy phones for mixing make you go for sloppy mids. And focus on treble too much. Also Quality of bass instruments will suffer greatly in character, as you cannot really work on the upper bass/lower mid content of the instruments, the fundamental will overshadow too much due to the boost. But "too little bass" only comes from newbies not referencing stuff against other pro mixes, with bass heavy cans you can also dial in the "right" amount, it is just it will sound very strong on them.
I have bass heavy cans and I use them for seeing if there is too much bass in the mix and how it impacts and which color the lowest end has... on them all other sound will drown behind the bass if it is too much. Also these cans are useful as they have shit resolution sounding veiled, so you can see what is appearant on the surface in focus of the listener. They have weak treble, so dialing in so I can hear it will make sure the very top end has enough presence.
for all other tasks I use dt880, they are the exact opposite of the bass cans. yes please mix and master on neutral cans with high resolution and certian brightness, it is like a magnifier. But they make me have a very bold mix with too much bass and mids if I solely use them without reference.
But point is any reproduction gear can be useful, just for the task the headphones are tuned to, also bass cans can have their good purpose. For mixing please use neutral cans with good stereo imaging.
Also: you know you can just develop an eq preset that will make you tune things right if you mix through it? with any cans...then it is only about resolution and stereo imaging and impulse quality of the phones.
