I use the Audio Technica ATH-M50[1]

I have a pair of noise isolating earbuds but you have to hit over the head to get my attention if I have the music above a whisper when I wear them

The M50's are over ear and seal very well so if you are listening at a reasonable volume you can't hear any office noise or people talking unless they are right next to you.

It's a nice balance between complete isolation and people being able to get your attention without waving something in front of you.

They sound great too.

If you're looking for noise isolating then the Etymotic Research HF5's[2] are great. They are earbuds that sound amazing and easily portable.

Both come with appropriate carrying cases.

I use and like the next model down at 1/3 of the cost, the Audio Technica ATH-M30[1]. They block loads of background noise because of the closed back, and sound great as well... and fit my cheapskate tendencies. The 11' cable is nifty too for when I'm using them at home to monitor while playing guitar into my DAW...
