hello i m using n6600 i want a software which produce good sound quality of my mp3s... i m already using mp3player 3.4 but its not upto that standard if u know any good software then plz help

I think that 6600 is mono sound. So, whatever is the player is always a weak sound. Try, for free, Oggplayer - free but good!

I'm afraid there's nothing you can do. OggPlayer is indeed a nice freeware player, but it doesn't come with mp3 codecs, the built in is just for ogg (not that this is a bad thing).
