I was in HMV yesterday for a browse as the wife bought more shoes (she has run out of shoes and needed more urgently). They had two pairs of Bose on ear phones on demonstration, the more expensive of which was just under £100. They are closed back, so should not leak too much sound, though it is hard to tell in HMV with all that noise. However, I really liked them. They have that Bose strong bass into the midrange signature, which is also my experience of hifi from the US, such as Grado. If you want to repeat the dynamics of the SR80s, find HMV or an Apple store (I am sure they have them there to listen to as well) or John Lewis (though I dont know if you can listen to any there) and try the Bose.
