As I'm sure you know, quality headphones make all the difference in the world. With hi-fidelity headphones, you can listen to music at a lot lower volume with less ear fatigue, and you'll notice parts of the songs that you've never heard before. It is assumed you're not listening to mp3's, as the compression kills most dynamics.
A while back I was searching for the right headphones for my listening enjoyment and for my recording studio. My buddies suggested some beyerdynamic DT770 Pros.

Unlike the beats, these headphones are meant to mimic exactly the way the music was recorded. The beats try to "enhance" the recorded sound by emphasizing certain frequencies (particularly the bass). If you think the big beats sound good, these are even more crystal clear. I was not impressed at all with these headphones for the first 2 months. I was told that they need to "break-in" and that they sound better with time. I stuck with 'em, and now they're my absolute favorite headphones I've listened to. They keep sounding better with age. After 2 years and countless hours of listening through them (I average 6 hours a day), I am beyond impressed. Now that I own them, I notice them in all the studios I go to, and in lots of live/studio videos of my favorite recording artists. If you want headphones that recreate the exact sound the sound engineer mixed them for, you can't go wrong with these.
If you want something that rattles your head with bass, check out the darth beyers (modded beyerdynamics):

When I first got my beyers I thought about sending them in to this guy, but I decided to let them break in. Now that they're broken in I couldn't be more pleased with them. You're welcome to try mine out sometime if you care enough to swing by and borrow them.
Then there's always the beyerdynamic T1:

I have to really restrain myself to not dump buckets of money down the drain with audio equipment. I'd rather have a $5000 stereo with a $500 TV than the other way around. I know I'm weird, but quality audio is definitely my weakness. I have to force myself not to read up on the internet or I'll be dissatisfied with my current speaker/amp selection.
Regarding those on your list, I don't have experience with the headphones themselves, but I do have experience with Audio Technica microphones. Bang for the buck, I have been blown away by the sound quality for the price I paid. I have definitely heard and used better microphones, but they cost 3x the price of my audio technicas.
