This is why studio monitors exist and referencing your mixes on different sources. I only use over ears or in ears mixing for quiet tracking and when I'm checking stereo imaging on a final mix. To be noted my signal is ran thru a splitter before I go to our in ear monitor rack and foh so I have two completely different mixes. Live if I can I try to dial my sound for the front of house seperate from my personal in ear mix. The sound isn't drastically different between the two mixes but it is enough to not sound ideal on either source if I don't mix them independently.
