Review title: Don't waste your money
Product review: After extensive research, I chose Sennheiser PXC 250 Noise Canceling Headphones to block base music played by noisy neighbors. As the undesired noise is not unlike that of an airplane's deep humming, this particular model seemed to be the best choice based on other reviews. Wrong! The headphones actually magnified the sound! Also, even when tested in a fairly quiet environment, the headphones magnify other random noises. Besides being ineffective in canceling noise, they created a very uncomfortable vacuum sensation in my ears, resulting in dizziness and head discomfort. Others who sampled the headphones experienced the same effects. I haven't tried another brand as of yet, but I can say that this particular model of Sennheiser headphones is vastly overrated.
