For the record, the following is what you have previously said about a Sennheiser HD 449:
I have the 449's ... So far i perceive clear detailed midrange, adequate but accurate bass (most headphones over do bass anyway) and very good highs, plus overall a natural warmish tone ... these are actually a good mix between accuracy and a little bit extra bass ... I can't really see how headphones could get much better than this to be honest
Also for the record, the following is what you have previously said about a Sennheiser HD 439:
i find these 439's to be better than all of them ... To my ear these 439's have a nice open soundstage, clear natural detailed midrange, non-hyped but still punchy bass, and nicely accurate treble range ... these seem to have more focus, immediacy and coherency, plus no exaggerated tones, and defines the whole frequency spectrum with finesse and class ... they don't appear to have any shortcomings to my mind ... and these 439's i use as monitoring headphones and i think they are very detailed and well balanced right across the spectrum with pleasingly accurate tone.
As for Sennheiser's ability to design headphones...
if a headphone is designed properly and is more accurate with all important aspects of performance presented correctly, you may find that hyped bass becomes undesirable. To my ear these 439's have a nice open soundstage, clear natural detailed midrange, non-hyped but still punchy bass, and nicely accurate treble range
Also, your opinion of Grado headphones seems to have changed:
I also tried all the Grado's, every one of them, and it seems to me that people who like them need to go listen to their preferred music on proper studio Monitor speakers, the Grado's don't give anywhere near the truth of the original sound source ... there's no way the Grados are accurate, and you will wonder where the hell is the bass and what is all that shrill treble and anorexic-sounding audio spectrum ... the Skull Candy Aviators beat the legs of any Grado headphone
one that is a no-brainer is the Shure SRH550DJ, the Shures are nigh on perfect ... The Ultrasones are about $129, and a damn good buy, the Shures can be gotten for $100, and the Skull-Candy Aviators are about $249. My pick of the three would be the Shures, i have all three of these headphones ... the Shures simply kick-ass all round, they back down to no one.
And for the record, here are some of your previous comments regarding the Audio Technica ATH-M50...
