sound isolated earphones or closed headphones?

["evs" onomatopoetik]

hi,
i have to buy new headphones for recording in the field.
i like the sennheiser hd25 as they really seem to seal you up from
the outer world ver well (even better than other closed headphones),
so you just hear what you are recording through the headphones and
not from the "outside"..
but my ears hurt when i wear them too long. but thats the problem
with most closed headphones..

now i thought that it would mabe a good idea to take sound isolated
earphones.
like the se210 from shure (http://www.shure.com/PersonalAudio/
Products/Earphones/SEModels/us_pa_SE210_content)

i know they are build for consumers, but they should be much more
comfortable to wear, so,
anyone have ever try sound isolated earphones?

all the best
emil
