I use hearing aids. I'm sure you know that your technician will 'tune' the balance and frequency response curve to your needs. I bought a type that allows separate left/right volume adjustments, since (as I assume is common) one ear has considerably worse hearing than the other. To explain, I am aware of another style of hearing aids where you tap one ear to increase the volume, or the other ear to decrease the volume, but BOTH ears are affected. This would not work for me.

I do not and would not mix with headphones. I only use them as one way of checking a mix. Wearing hearing aids doesn't present any problem when listening through closed headphones; just watch your gain. I used to love open headphones (unless tracking) but find the pads rubbing against the hearing aid (mine are over the ear, not in-ear) makes a bit of noise with any motion.

For live performances, since I play horns, I remove the hearing aid from the better ear, so I can better hear the ambience of how I sound in the room or hall.

I don't know if any of that helped you, but good luck.
