My HD650s definitely rank amongst my most favorite possessions. As far as accuracy goes I tend not to get too hung up on these things, all I know is that between these, several other pairs of lesser quality headphones, my djing headphones (an important reference) my car stereo, running laptop through the telly, & any other audio outputting device I can find! I get a pretty comprehensive feedback of my mixes.
If you want to stretch to the 700s or some Audeze headphones, then DO it! Do it & never look back! Treasure them & your creative time in the small hours.
