sorry for absconding for sometime!
hehe....
yes, thats exactly what i said. i've tried it sometime and it works! the fm mic i bought was for 35bucks! i already had an fm headphone.. dun remember its price. but when i switched it on wid just 3V the range was pretty good. my home was at 2nd floor that time and i cud tune my car's fm tuner and listen to the music that was being played in winamp.
piece of advice: try wid 3V supply and dun go above 6V. it may wreck ur fm mic. i busted 2 mics in my quest to get clearer audio. tho more voltage may temporarily give u better output but it'll kill ur mic faster. i wudn't suggest using a 9V supply. what u cud probably do is turn off the equiliser in winamp or any other media player.
