The Sennheiser PXC 250 noise-canceling headphones create a quiet space in which to enjoy your favorite music, or you can use them to simply turn off the noise and bustle of the world around you.

The PXC 250 headphones cancel out ambient noise in two ways. The comfortable earpads are the first layer of defense, producing a physical barrier that blocks outside sound. Unlike many other noise-suppressing and noise-canceling models, the PXC 250 headphones fit on top of your ears but do not completely surround them. The other half of the equation is the NoiseGard electronic noise-canceling technology that actively eliminates ambient sound. The PXC 250 headphones are most effective at reducing low-frequency noises such as aircraft engines and highway rumble.

Sennheiser makes some of the best-sounding headphones in the business, and the PXC 250 headphones follow that trend. They produce accurate highs and natural midrange tones, but their small size causes a reduced bass response. This is not to be unexpected, as bass is not a strongpoint in most headphones.

The PXC 250 headphones have an external battery pack that is attached to the headphone cable. A pair of AAA batteries is required for the active noise reduction, but the headphones can still be used without the batteries. However, the battery pack is not detachable, so it will always be there even if the batteries aren't.

The PXC 250 headphones are foldable for portability, and they come with a belt pouch. The 1.8-meter cable has a miniplug jack, and the package includes adapters for 1/4-inch plugs airline-type double-mono jacks.

With a price that the noise-canceling competition can't touch, the Sennheiser PXC 250 headphones do an effective job reducing noise and a great job reproducing your music.

Pros: Good price, effective noise cancellation, relatively compact
Cons: Poor bass, non-removable external battery pack
