Even being on ear the Cal has the best comfort out of what you have listed. The most neutral would be the 440, but the detail revival is fantastic. Really good at the price level. The HD448 is neutral ish, not quite as Flat as the 440, a bigger soundstage, better comfort, But just a tad behind the 440 in details. still quite good tho. Haven't heard the Sony, My pick, The Cal....it is slightly V-shaped and RAWKS with Rock and Metal. I seen your music taste in the other thread, basically my playlist...the 440 coming in a close second,
Both sets are dead on with each other. The only thing keeping the 440 from being first is it can be hot on the top end with some music and the comfort is slightly worse. BUT you can buy 840 pads and they fit the 440...Much better!! If you need full over ear and neutral 440!!!
