Sorry if I'm ignoring everyone's post, but I'm currently using a 3.5mm L shaped cable to 3.5mm (not the stock cable on the t50rp). I read somewhere here on the forum that plugging up the sides of the locking mechanisms will balance out the bass balance issue. It really did! The balance is off by 2-3db starting at 40hz (lowest that I can efficiently hear through the fostex t50rp's), to a mere 1-2db stopping at 120hz. I took the risk of plugging the holes with Crayola Modelling Clay.
