My professional opinion on the matter is, a tool is a tool. Any speaker can be learned just as any headphone can be learned. Speakers are always preferred but not always an option. At that point you can't go telling a client that the mix won't be done today because my speakers aren't around. Find a headphone that sounds similar signature wise to your favorite nearfield and learn it.
This is it. *know* your tool and it won't let you down. In headphones I'd look for a nice resolving high end to really dial in the fine points in setup / micing up a drumset. Then move to monitors.
Gotta mix and reference with dr. dre beats and apple ear pods because most people are going to be listening to your mix through beats/earpods so make sure your mix sounds decent on the dre beats and earpods.
Your mix may sound good on hd600 but will sound different when some uses earpods or beats.
Just add gobs of compression at mixdown.
