I use various types of hearing protection depending on the situation (I too have a big melon). The simplest and cheapest option would be
soft foam ear plugs inserted correctly (Howard leight, etc), which are nice when it's hot out.

But if your preference is ear muffs, I have experience with several sets of Bose noise cancelling over the ear headphones as well as noise cancelling earbuds that I use on the ZRT or when using gas tools, but not a fan of over the ear when it's hot out & not a fan of earbuds for more than 2 hrs at a time. I wear glasses with my over the ear headphones without any issues.
When at an indoor range, I double up with foam plugs and electronic impact muffs, when shooting outdoors, just electronic muffs.
If $ isn't an issue, for overall comfort, I prefer the newer Bose Ultra noise canceling over the ear headphones, their newest offering has larger cups and more adjustment, 3 levels of noise canceling adjustment, but are pricey at close to 4 bills. They are hands down the most comfortable over the ear headphones I've ever used.
