Portable audio takes on fresh life with quality headphones, and Sennheiser's folding, lightweight, closed-ear PXC 250 is designed to keep outside noises out and headphone sound in--perfect for use in busses and libraries alike.

lncrease the peace! The PXC 250 features a noise reduction unit that cancels out background noise.

When engaged, NoiseGard active noise reduction drops steady-state low-frequency noise (from about 500 Hz and below) by 15 dB--which the human ear perceives as more than halving the noise--thus enhancing the clarity of your music. The noise reduction circuit requires 2 AAA batteries (not included), but the headphones work fine without the circuit engaged.

Sennheiser's fold and flip design lets you turn the ear pieces 90 degrees and fold the headphones closed. Their ported design lets them move more air for greater bass response.

What's in The Box
6-foot Kevlar-reinforced cord, .25-inch stereo adapter, airline adapter, belt pouch.

Buyer's feedback: - * Better than expected. ...
I take public transit daily which includes a bus and train ride. These headphones work great to cut out the background noise from both. They are comfortable and sound great for the price. My only hang up are the cords.

Buyer's feedback: - Can't handle office interference
I tried these out in a local HiFi store and found them to be very nice headphones. The sound was quite 'tinny' with the noise-cancelling circuit off, but a very rich and beautiful sound with the circuit engaged.

However, I ended up having to return them. It turns out that the circuit wasn't shielded against 2.4GHz spectrum, and in the office it suffered an incessant humm from the 2.4GHz devices. Most disappointing and I had expected more from a product designed to cancel noise in the office (I had purchased with the intent being to use them in the office, and for travel).

I would buy them again in a flash if they produced a model that was shielded from interference.

Buyer's feedback: - * These healphones a OK but not great ...
I looked at a variety of active noise cancellation headphones. The BOSE high-end ones were far an away the best in terms of eliminating external sound and sound quality. They are also very expensive and I just couldn't justify the price. I found the Sennheiser's to be the best under $100 so I went with them. They are reasonably comfortable, the sound isn't as bright as I would hope and the external deadening is very obvious but not as great a it should be faced with variations like people talking. If you are price sensitive then they are not a bad pick. If not then move to the next level or be disappointed.

Buyer's feedback: - Good for travel
I bought two pair of these for an oversees flight. The batteries easily last for the 9 hour flight. They were comfortable, not too hot and had good sound dampening cutting out most of the engine noise. They had good range for music and in-flight entertainment. No where near as good as the bose, but for less than 1/3 the price, I'd recommend them to a friend. Folded up easily for storage.

Buyer's feedback: - * Sennheiser PXC 250 Active Noise Canceling Headphones ...
They are okay, not too comfortable for wearing for a long time but good value for money. I'm not sure these types of headphones do anything more than cancel out aircraft noise because when used under other continuous background noise scenarios, like with a lawnmower, they seem to block only the same frequency as for aircraft noise.
