I have the Monarch Mk3 and it’s super comfortable for me, fits like a glove. My ears are not that big.

In comparison, I have the VE Ext (long shell) and Odyssey (large shell) and these are not so comfortable for me and cause some discomfort and pain after some time.

I'm the happy owner of the MK3 and to my regular shaped ears these are the best fitting IEM's I've ever had.
The isolation is practically perfect.
