Indeed I think many open may be more or less divided between fully open (leak a lot) and semi-open (leak less). I don't have the Clear yet but I understand them re. this aspect to be similar to the Utopia and Elear, belonging along the HD 800 to the fully open kind. In what I call the semi-open kind I put the following among my headphones with some impressions: AKG K812 (treble too high though not as bad as HD 800), LCD-X (too dark; attacks too smooth for me), PM-2 (too dark; attacks too smooth for me). At this point I would not go for any of those (in general they may have been outclassed by newer headphones, though they might still be great for more specific musics). I don't think the Clear would suit your requirements, being full open. If you can wait and hold for a while, then I can recommend you to wait for the coming new Focal headphones, not announced yet at this point, so secret... If you can't wait, then I can recommend you to go for the AKG K872: closed headphones with a very wide soundstage like open headphones, more neutral then the semi-open headphones which I just mentioned above, good bass, better attacks than HD 800 though not quite as much as Focal's headphones. What kinds of music will you be listening to?
