Well, I've now tried all 4 sets. The Grados have gone back into the box, and the Senns barely made it out--very disappointing, almost as bad as the Wickeds. I'm pretty sure it's going to be the Etys, but I should give the iMetals another shot. The Etys definitely have the best isolation, but my ear canals still feel like they're being violated.

I am the Doctor, and THIS... is my SPOON!
