No problems with my Bose A20 inside a LH050. In my experience it depends how well the ear cups sit and seal in your head - in certain conditions with a poor seal you'll have low frequency feedback (drumming), but if they sit correctly it works door on or off. Easy to adjust with velcro pads.
I've had the Bose in there for about 4 years now and you couldn't pay me to go back to a passive setup.
