I really do not like the audio quality in my w580i..It lacks loudness and mainly the megabass.

I hear some songs in Normal mode in eq..change it to megabass..Very very slight diff in the thump. I use the default in-ear phones..b4 I had w300i and the megabass i awesome.

Is thr a acoustic file which givs me the real thump for megabass and loudness??

If so can any1 name it??
