I sometimes work on conference calls from noisy coffee shops.  Would like to get a somewhat portable headphone that has a really good microphone so that people on the conference call don't hear alot of ambient noise.  Would prefer a headphone that isn't too huge and will fit in a messenger bag and doesn't look like I'm in a sound studio.
 
Please let me know your top 3 suggestions...
 
Thanks,
Chris
