Tired of taking your CD or MP3 player onto a plane only to hear the guy next to you better than the music itself? Do away with the problem for good with the MDR-NC40 noise-canceling headphones, which reduce ambient sound by a dramatic 10 dB so you can enjoy your favorite music distraction-free. The headphones work by synthesizing ambient sound with the noise-canceling circuit, thus reducing the commotion before it reaches your ears. In the meantime, the MDR-NC40's neodymium magnets deliver a wide-ranging frequency response and clear, rich tones whether you're listening to delicate arias or ear-busting metal. The headphones serve other purposes as well, such as blocking at sound while you're trying to nap or honing in on hard-to-understand passages of a voice recording. Appropriately for a travel unit, the headphones fold compactly for easy storage in a carry-on or backpack. They also fit comfortably over the ears thanks to the soft ear pads, which listeners can wear for hours with no ill effects. The MDR-NC40 also includes a plug adapter for connecting to a stereo or, alternatively, an airline dual jack for enjoying in-flight music services.
