Which of the headphones listed in the title should I buy? I want good SQ with a very slightly exxagerated bass. I also want comfortable, noise isolating (not noise cancelling, as I've heard it makes the SQ worse) headphonss that don't require an amp (just driven by an iPhone 5 with dongs in the regular bit rate). Prefferably, the headphones should be portable, but that is mot my main concern, just an extra bonus. I want headphones that also have a good build quality and will last several years. Which headhones should I buy?

Also, the sennheiser hd518, hd558, and hd598 are options. Thanks for the help!

I forgot, I also want a relatively good soundstage.

Argghhhhhh!!!!!! I keep forgetting to type the stuff. I would also want little sound leakage.

The Sennheiser HD5XX line might not fit your needs as they require an amp to sound good and also they're open back, which means sound leakage and no isolation.
 
The M50s are always a solid and very common recommendation for everyone in a similar to your situation.

M50 has rubbish soundstage
HD5-- line has rubbish isolation

isolation and soundstage don't normally go together, 
but a good choice would be the Beyerdynamic DT770
since it has okay isolation and okay soundstage
