Yes the Superlux are semi open and the Samson are open. I'm not really that concerned with the sound leakage as long as it's not too excessive. It's not like as loud as if I was using speakers is it?
Yeah the 840s are way too much for me. The cheapest I see them is $180 atm. But thanks for the suggestion.
I think I'm just going to order the Superlux unless anyone thinks I shouldn't.
