What do you mean by “noise reducing”? Do you mean headphones that actually are noise canceling, or are you looking for headphones that are very isolated?
There are a number of headphones that are built into ear protectors like those used by airport workers and on weapons ranges, but they are on the pricey side.
If you don’t like the Sone MDR-7506 you may want to check out the Sennheiser HD 380s; about US$130.
Peace,
