Dude,I do not like muddy bass either!
No one does actually,for example,a properly amped DT 770 or 550 PRO or HD25 will satisfy a hardcore basshead(of course someone who wants to look beyond single note bass your beloved BOSE headphones tend to produce)
Have not heard the Sony multi BA phones yet,but have heard junks like S4,that particular weird Bose offering.
They precisely define bloated muddy bass.
But I have also heard(and have)top notch iems like IE8,SM3,IE7 and W4 and they do sound like gems(and some of them do have skull rattling but precise bass,not the loose sloppy bass of S4/CX series,there is a reason an IE80/8 costs 10-15 times more than a CX300)
But you need to hear some middle tier stuff first to appreciate them.
And of course a crappy ipod headphone out or a heavily coloured BBE processed signal wont do any good to the top of the line universal iems.
PS:In case you have not heard the mentioned names,google 'em and if you want to audition them,you are more than welcome!
