5800 is good only with inears but with cans the volume is insufficient. N91 is probably the loudest phone i've ever heard. SQ is good but very far from being flat; bass is highly boosted treble is somewhat grainy but u'll not notice the graininess much with cans. Also n91 hisses a lot with inears.
As for other mobiles i've owned se 810i, k750,w550i,nokia5300,5310 &se k790i.Out of these only k750i sounded decent(only with older firmware). 810i was good but had very low volume.But still finally none of the mobiles come any close to stand alone players.In case if you want best possible good sounding phone get either k790i or k810i & flash them with different sound drivers(available on esato.com) using 'far manager'. U'll at least get a 'nano' sound.I did edit my w810i & was very pleased with the outcome; it had better bass than my touch 2g!!.
As for nokia offerings ,they sound pretty imbalanced & smudgy(the express series)
In case u want good\ok sound right out of the box get a w980i.
