There really is no comparison between the T1 and HE-6 to be honest. One is a heavy ortho which is pretty uncomfortable and has questionable build quality and requires a massive amp just to sound decent. The other isn't and doesn't on all accounts. The T1 wins in comfort, quality, efficiency, and sound quality in my opinion. Even though my top dog headphones are now the LCD-X and XC I have decided to keep the T1 as a lighter brighter option for days when that is what I want. The HE-6 went straight back to the factory.
