As always, a very thorough, and informative review. I have been keeping my eyes on these and it does sound like a signature I could enjoy for portable use. I am currently switching over to Sony MDR 1A for portable from my V-Moda XS. The switch has nothing to do with sound quality per say, I just get bored after about a year with a headphone and want to try another signature. I will certainly drop by my local audioshop and see if they have these on demo as I suspect they do. Thanks for the review, much appreciated.
