OK it's a new challenge. I have now beaten my previous reference (for non-isolated in ear) the Sony 21's and just interested to know if anyone knows of something that can beat these.
The headphones are the Audio Technica 7 now listening to music through theses and they are great. These were suggested by a forum member so I have him/her to thank.
Note:-
I have tried the Senn MX series and they beat these.
Don't suggest the shures or Senn cx300 as these are isolated
Please don't suggest the overears like HD25, HD650, Grado 80, etc as need to be discrete
No comments about just listening to the music and be happy

I am happy for now

just interested to see what else is out there.
