I have a pair of Ultrasone Pro 900 and they are closed but still leak a considerable amount, and thus not suited for office use.
 
Has anyone hear come across a quality pair of headphones which leak surprisingly little (or perhaps no) sound?

I use T5p in the office and no one complains. Dunno if they are the least leaking HP, but they do the job.

The Audio-Technica M50x seem like a good closed type of headphone. Open headphones will disturbed other people, specially in the office. I'm considering to buy a pair of the M50x for use at the office or places where people may get disturb.
