I use the Apple in-ear headphones(the $79 ones)

I wouldn't buy them for retail, they aren't that good. I'm lucky I got mine for free.
 
B&W P5, just the cable is sooo thin and delicate! i cnt believe how good the quality of the headset is only to be let down by the quality of the cable.
 
I use a pair of Ultimate Ears Superfi 5vi. It's noise isolating. It works great for me.
 
I use Sony's "Sweet Little Buds".

They sound awesome and don't come out. I leave one in my ear while I am working and never have an issue...the apple headphones sound great but fit terrible. I wish they would fix this.

I have also spend sooooo much $$$$ on trying to find the perfect headphones. ;)
 
I'm a headphone junkie! I alternate between the following:

-Westone es3x customs (I use these obviously when I'm wanting to get the absolute best sound quality)
-Sennheiser IE-8's
-Shure 530's (gym use)
-Klipsch s4's (gym/running use)
