echelon

Hi people, I'm currently looking for a headphone that cost below $300. However I would want the headphone to sound clear with good soundstage, most importantly for vocal and instrument, I will need some bass too. I am looking at Grado SR225 and Sennheiser HD595, please recommend me anything that deserve to be considered. Also on the other hand, I would like to ask if there is custom cables available for the IE8 too, thanks.
