Headphoneus Supremus
I own the DT880 (and the HD650 and I’m borrowing the K701). I just sold the K501 (after trying it for the third time). Although the K501's midrange was very clear and sweet, the lacking bass affected the entire spectrum. Not only were the deepest notes absent (which is crucial with organ and certain chamber pieces) but nearly every sound exhibited a hollow, silhouette-like effect that was intolerable. I used the K501 exclusively for 2 weeks (source is DAC1 and amp is M-cube) and this issue plagued the 'phones throughout their tenure. Their soundstage, while very wide, was not deep and also negatively affected my enjoyment of jazz and rock. The HD650 and DT880 both have narrower, but deeper soundstages, and the K701 is dearly as deep as the Beyer and Senn, while demonstrating just as wide a soundstage as its little brother. The Beyer sounds slightly colder than the DT880, but the Beyer's bass presence and overall more balanced sound is preferred, IMO (and its bass is just as clear and tight as the K501). The K701 is another matter...
