Title: SNH5500
Review: I agree with Researcher. This is a great buy for the frugel buyer. They are great office headphones and reduce a lot of the hum of the air conditioning units and the air moving through the buildings. Though, they do not cancel all noise, they are practical. I recommend them as a great buy.
