Thanks for the info!
Best price I can find here in the UK (incl. EU) is £289 from an authorised dealer. Where did you get yours from (audiocubes don't list the SE530)?
And how "big" are your ears - as mine (and the missus'es) are pretty small?

At first glance the UM2's price point was very tempting but when taking customs (import by Fedex -> a given), and the extra needed accessories (you mentioned, come with SE530) into account, the advantage is almost (but for £60) gone. And I suppose the SE's would have a much better resell value, too, if ever wanted. Hmm
