BUT the biggest factor is the direct sound going into the canal RIGHT inside the canal. Just my opinion ofcourse. Ear buds are *probably* NOT much better. I think the safest are cans and reasonable volumes, and not for extended periods of time.
Safe listening to all.

If the ambient noise is, let's say, 85db, then just to hear your music, you will HAVE to listen to your earbuds/earphones at a minimum of 86db just to hear it. Probably louder to hear it properly.
So if you reduce the ambient noise by 25db (as many IEMs do) then you can listen at, let's say, 70db.
85db getting into your ears is 85 db getting into your ears, it doesn't matter how direct it is, it's still damaging.
There's possibly an argument on a health and hygiene basis here, but it doesn't matter how close the source is to your eardrum, it matters what the decibel level is once it hits it.
You said it best when you said 'reasonable volumes.' It doesn't matter what is making that volume, it's the volume itself that is the critical factor. The argument for IEMs is that it just makes hearing the music more likely at a lower volume than a non-isolating earphone/earbud would.
Reasonable volumes should be adhered to irrespective of what cans you use.
