I am the one who wrote that in the impressions thread (for CanJam NYC).
I am not sure what I was "doing wrong", but putting them on my head (I am not wearing glasses) - I could hear the show floor ambient noise a lot more than other better isolating headphones (such as Mr. Speakers AFC for example).
Wasn't trying to suggest you were inept, sorry if it came across that way. It does make me wonder if a pad wasn't seating correctly or something as your notes do not match any other that I have seen or my experience. When 4 of us have all chimed in that they isolate at least well enough to wear on a bus or plane and your review is in such complete disagreement, one starts looking for what is different.
