Still to this day, I recommend Sennheiser HD 25-II's. These things are indestructible. Plus they sound pretty good as well. When you watch any sporting event on TV or any big DJ, the majority of the time they will be using these bad boys.
I've had mine for well over 4 years now, not really looked after them very well, but they are still going strong. Every part is replaceable too.
Best of all, they are still cheaper than a pair of Beats by Dre.
