Nice review; thank you. I own three pairs of headphones that I like a lot (Beyer DT880, the Audio Technica ATH AD700, and Sennheiser 595) but I keep returning to the Audio Technicas. They pair very nicely with my amp (the audio engine N-22) and the sound quality is excellent with a wide variety of music. My observations are much like yours: they sound great, the fit is good, and they do lack a bit at the low end. They are also very easy to drive and sound good even with the audio out from my laptop.

I've had mine for a year now and am finally confident enough in their abilities to push them a bit with the volume and they sound just as great as they do at low volumes but more impactful. Next to the Koss Pro-4AA these are my favorite. Hooked up to my Onkyo TX-8555 they deliever plenty of balanced bass for non-bass lovers.
Yes the Sennheiser HD-202's are more bangy and great for bass type music. Still their lack of refinement with the details makes them less immersive then the Audio-Technica Ath-AD700 which brings out every possible emotion from me. The HD-202's are more for my destructive mood indulgences such as playing real time strategy and first person shooters where i prefer not hearing foot steps since thats just not realisitc after an explosion
Thanks for the great review
