Hi, I've been visiting these forums a lot these past few days, and figured now was as good a time as any to make a post about this. Sorry if this is in the wrong section, but it seemed like it was the right one.
 
At any rate I am looking for headphones with an approximate budget of ~$150, but I would be willing to go up to $200 if is needed. This is my first time getting a 'nice' pair of headphones, so I am a bit lost to some of the nuances that other people seem to pick up about them.
 
What I am looking for:
 

1. Closed
2. Over the ear (ideally)
3. Detachable cord
4. Good quality sound (if that wasn't implied)

 
Now I have narrowed my search down to these headphones at the moment:
 
Brainwavz HM5s
NVX XPT100
Shure SRH840
 
I also really liked the V-Moda Crossfade LP2's, as they have a detachable, braided cable as well as a very nice carrying case. However from my research it seems like they are bass heavy, which I would prefer not to have.
 
Additionally if anyone knows of any other headphones that I should be looking at I would appreciate information about them as well. The one thing on my list of 'requirements' that I really don't want to compromise is the detachable cable, as if I am spending this much money on a set of headphones I would like to be able to easily replace the cord if something happens to it.
 
Thanks!
