First: Stanton 2000s (still ok)
Now: Sennheiser HD25
The Stanton is ok, buth with that, everything is said. Just a nice headphone, and nothing special. I've used it for about 6 months and the headband is cracking buth still ok.
My Sennheider is like heaven, very good isolated from noice outside the headphone, much power and a clean sound. Practicly undestroyable and every single part can be replaced...
I also started to like the on-ear wearing that the HD25 has since the first moment i've tested it. No more over-the-ear headphones for me, i love my Sennie
