Sennheiser PXC 250 Consumer Headphones

I work in a typical corporate cube with one side open to a lot of foot traffic. My cube neighbors across from me run a fan and air cleaner all day. Needless to say, this cause me a lot of irritation.

I picked up a pair of these headphones and I can honestly say that it effectively blocks out 100% of the noise. Couple that with my Gigabeat and I can't hear anything.

They fold into a supplied bag so they are nice to transport. I'd be careful with them though. Treat them gently and I'm sure they will last a long time.
