I thought I would post a complete review but it does not make much sense IMHO... Basically, just check this graph above and you already know what to expect:
1) K712 Pro being significantly more bassy with slight midbass emphasis while HD800 presents bass significantly more precisely, better imaged into the space in front of you and with zero impact on other instruments (K712 Pro bass size is too much, it leaks and veils other instruments and voices). K712 Pro bass is very similar in nature to the HD800 but significantly more present (I would say artificially present but it will be just right for the majority of folks here).
2) Good mids on both but while completely neutral on HD800, quite shouty and a bit sibilant on K712 Pro, Yes, the 2khz emphasis is still present and still hearable. However, in comparison to previous x7xx headphones, the bass quite successfully masks this. Bass also gives vocals enough depth, finally (hello Q701).
3) Highs are more consistent on HD800 (more linear) but I would not recommend both headphones for very loud listening... There are better headphones for that. There is a definite 7-10khz (roughly) peak on K712 Pro making drums quite present along with their midbass emphasis. I dont see it as a bad thing - in comparison to DT880, these AKGs still sound balanced enough while Beyers are significantly unnatural (cymbals) due to this more apparent trademark peak.
HD800 have more expansive and developed soundstage, are a bit faster, better imaging and separation... Much better detail and microdetail. Also being more transparent and SIGNIFICANTLY clearer and cleaner while K712 Pro are a bit veiled due to their bass. K712 Pro also sounding rough or dull/plasticky-sounding in terms of overall sound quality (mid-fi vs high-end, you know). In comparison to HD650, they are definitely not as veiled and what's important - k712 pro are lightning fast in comparison to HD650.
HD800 significantly more comfortable - perfect pads, perfect headband, no clamping force... K712 Pro having still not completely comfortable headband, significantly higher clamping force (that memory foam is very stiff and makes the pads clamp even more) and what's the most important thing - my ears are constantly touching pads or drivers with K712 Pro! While I do not feel HD800's alcantara at all, I am always aware of K712 Pro pads' material.
Any advantages of K712 Pro? Well, they are much more compact and durable, have lighter cable connected only into one cup (more comfortable) and offer more forgiving nature as they are not as good technically as HD800. They are also a bit more versatile for the majority of people soundwise due to the significant amount of bass. Some people will prefer K712 Pro way to render drums.
The best mid-fi headphones? Very likely IMHO, they are very versatile and present very few flaws in comparison to typical mid-fi headphones... Also look into Beyerdynamic DT880 600ohm if you don't mind artificial treble and rather bad soundstaging. You could also like HE-400 but dont expect neutral frequency response.
