Out of the box they were pretty good but bright, then at about 30 or 40 hours the sound became so disarrayed and dull that I could not listen to them at all. At about 100 hours (or a little bit earlier) the sound was pulled back together (now minus brightness), and at 150 hours the bass became...

for letting us know about it. In my brief trial of the two (using both, Tascam as SS and Musical Fidelity X-CAN v3 as a tube amp), I also preferred HD-650 as the more involving (whatever stands behind this phenomenon) though admitted a seemingly more balanced tonality of HD-600.

Me too. In a brief comparison 650 sounded more involving to my ears compared to 600.
