regardless of specifications and performance, headphones are way more individual sensitive than speakers.convenience, head size, shape, earshells it all matters to get a perfect headset. i get headaches and listening fatigue from overdefined HD580/HD600 bass. did not try hd650 as an example.
your best bet is either swapping them one after another by purchasing/selling or visit a good headphone shop or even audio festival to make up your decision.
