Dave,
I have just bought a pair of Harmon Kardon CL on ear headphones.
They are not the noise cancelling type as I don't really require
this facility.
They are very comfortable and have very good reproduction.
They are not the bass heavy things that are being pushed by
a lot of brands these days.
I don't know if HK do a noise cancelling version.
I can't stand those ear plug style things!!
Every set I have ever tried are very uncomfortable, fall out all
the time and generally don't sound very good.
I can recomend the HKs that I have so you should see if
they do noise cancelling ones.
This is where I got mine.
