Hmm, do the dj cans fall under "portable"?
I'll be getting the Q40 soon, so I plan on making a comparison thread between that and the M50/SRH840 (either that or just add to another one).
I would call most DJ cans portable as they are at the very least flat-folding. I think I said a few pages ago that to make it to this thread the can has to possess at least one of the following: a flat-folding or collapsible structure, a short/thin cord, or a supra-aural design. So yeah, even my Ultrasone Pro650 is portable as far as I'm concerned.
50mm drivers. Wow!! That sounds like a fun headphone to me already. I like Denons. Looking forward to the release of this new line.
How's your review of the EM7 coming?
Yep, I believe that the current Denon D2k has 50mm drivers and that certainly falls in the 'fun' category.
EM7 review should be up tonight or tomorrow. Adding something to the thread takes me longer now than it used to with the old Head-Fi .
