you have a fry's electronics around you? they usually sell the sony v6 for 80$ (at least its that much in AZ), and i know compUSA sells a couple of sennheisers; 457, 477, 497 and 500 (457 and 497 are the only decent values if you ask me...avoid the 500's...made that mistake a year ago).
150$ for triports? you could get _much_ better sound for a lot less.
edit: just noticed you mentioned bass...the 457's are a warm sounding headphone with a good, but not excessive, amount of it...excellent beginner can for a basshead. something like 50$ retail too, not near as large an investment. even after i picked up my grados and akg's, id still go back to the 457's for a little bassy fun every now and then. and although i havent tried them, from what ive read the v6 provide a good amount of not-too-bloated bass. but its all subjective, so...
anyone else with some advice?
my two cents
